4+ year old video and you're still helping fellas like me out! ordered the capacitors off Amazon, followed your instruction and fixed my TV for $6.03. Thanks very much Tampatc!

Awesome set of videos- Very easy to follow and I sorted my 44" TV that had been sat in my garage for a year. Cost me 59 pence for a new 1000uF capacitor and 40 minutes work. Awesome. Cannot thank you enough.Just awesome.

Hi mate it's good to see your videos again, it's a while since I repaired plasma tvs and it's great to get a refresh on doing it again, so thanks a million for your videos and great work and help. 👍

You saved me 1,000 bucks. My better half was all set to buy a 60 inch Sony before I fixed our 52" for $5 in capacitors. Well done, good job.

Sub'd..great video. I have electronic s tech degree that I never get to use and live in an upper scale apartment complex where people just leave their TV's by the dumpster if they either move or have an issue with them. I think I'm up to around 4 TV's so far this year. The latest has this same issue.

Really great and informative video! I woke up to my tv clicking on and off. I was able to sort it out, at least for now, by unplugging it for a couple minutes. Still, I wanted to see if this is a common issue and plan ahead just in case. Thanks so much for a how-to that isn’t obnoxious, overly technical or boring.

excellent job showing what your doing and what the problems can be. And please don't be mad about Samsung and capacitors, most do not have this problem, and many don't have it for a very long time. Plus its easy to fix. I've had my current tv for a good 5+ years, and only recently has it had this problem, and currently its an easy problem because without even replacing stuff you can simply blow a hair dryer in the vent of the tv to heat up the capacitors fast for the tv to work fine, The more capacitors that fail the longer the tv clicks/to warm up and come on. If you know of a local repair shop you can just take the board to them they can soder in/out new capacitors for cheap.

I love all your repair stuff.I archive you and a couple of others.It is a great reference for trouble shooting. Thank you.

These how to videos are awesome!!! Now, as an electronics engineer with over 30 years experience in several industries including consumer video electronics, I’ll point out a very key missing point regarding the caps. The failure mode is outgassing due to overheating hence the swelling and bulging - no surprise as most know. And, true, replacement caps are easily available. But here’s what I want everyone to know and it is not being mentioned on these how to sites. The problem with the caps as you might imagine are that they are cheap, Chinese supplier go figure. The reason these caps overheat is they are as this video explains, are used to filter fluctuations on switching power supplies. so what occurs is what we call ripple currents. I will simplify Ohm’s Law by restating that voltage equals current times resistance, but what is that play in these failures is the fact that there are time varying currents i.e., the ripple currents flowing continuously through the capacitors due to the switching mode operation of the power supplies. so, now the problem with this. no electrical component has ideal properties in the real world. let’s keep it to the discussion of capacitors. capacitors have what’s called equivalent series resistance. as with the operation of space heaters we know that resistance with current flooring through it will result in heat. so overtime this ripple current flowing through the parasitic ESR of the capacitors will continuously generate heat which in turn causes the electrolytic material to outgas and eventually bulges the capacitor and it loses its capacitance characteristics. in the complement industry for electro lytic capacitors there are specialize capacitors they cost a bit more but they have very low ESR. in safety critical applications Mike automotive and dustrial and avionics it is absolutely important to select low ESR electrolytic capacitors. so, after seeing these how to saying go out and get replacement capacitors I have waited long enough to hear someone mention that the selection should be to get low ESR electrolytic capacitors. to put it in real terms I repaired our Sam song back in 2009 with low ESR electrolytic capacitors and have not had a problem since. A friend of mine did he is independent of consulting me and he had to go back in and replace them after about three years. by that time I got wind of his reoccurrence and got him some low ESR electrolytic capacitors. so my suggestion to the creators of all how to videos for this problem is to please guide people toward low ESR electrolytic capacitors and not just a garden-variety replacement. good luck off.

THANK YOU!!!!!! Your video helped me fix my Samsung Plasma TV after a power surge. Your instructions - especially testing the standby voltage - helped me isolate the problem to the main logic board with all the inputs. Found part for $80 on ebay, installed it, and our television is now working like before! GREAT VIDEO!

You are very good at sharing/teaching this level of info. Thx!

Thank you for what you do and everything you have done and your contribution to KZfaq and thank you for sharing your knowledge.

Your video is the BOMB. I bought a small kit that had a plethora of capacitors.I replaced 2 defective capacitors. Put TV back cover on, works perfect.Thank you for the very informative video.

Great video, clear step by step explanations.

Thank you for this helpful tutorial. I'm having this exact problem with a Samsung TV right now. I'll try changing the capacitors first.

Excellent video!

Thank you for this very helpful video. I’m not very handy when it comes to things like this. But I’m going to give it a try. I just had one question that I’m hoping you could answer that may narrow down the cause of my on/off issue. My set does not click on/off immediately. I’ve been timing it and it seems to turn off than back on every 4-5 minutes. In your experience does that lead you to think it’s one issue over another? Thanks again for your helpful video!

Question for u, I have Panasonic TH-50PX60U Plasma TV. It has no picture but the sound is fine. Do you think it has the same problem as Samsung TV Y-sustain board went bad? Thanks ahead of time.....

Thanks again for sharing!

Excellent repair tutorial!

Love your videos Sir all information with no bull

Hi m8 thank you I looked at your video and ordered a replacement power board. All working after replacement.

Thank you so much for sharing!

Thanks for the reply, I wonder if it is worth replacing the sustain boards, and I was confused to find a Tcon board on a plasma TV, I was not aware they had them now. It is an October 2009 unit. I guess if the sustain boards are cheap enough, it might be worth the expense. the TV was free. Any words of wisdom or videos that would pertain to this unit or one very much like it to help me a little to verify which sustain board it might be. I am a notice at testing components on boards. HELP

Thank you for the information that I needed, because I have 2 CRT widescreen TVs that has the same problem, both TVs switch on and off randomly because they are 30 years old as in tripping, and I understood your logic because you spoke in English, that's my language, I have googled other videos about the same CRT widescreen TVs and they were foreign. The make of 2 TVs are Beko and Akura two different TVs but the same models.

thanks ; i like your videos , very interesting

Thanks Tampa Tec your a good man

I am following your video to repair my 32" TV , it is OK . thank you very much !!!!

i will try this method on my tv... tnxz for making this video...

Great video! No drinks near the electronics!!

video was great so I have 1 question you know sometimes you can go back with a capacitor that is larger than the one that comes out. how do you decide what is to large for that capacitor before it starts to damage the board?thanks

Thanks for this tutorial it as been real helpful to me

Awesome instructions....thank you so much.

Tampatec very much enjoy your vids. I have a Samsung TV 50" I think it is 50". I will not be using it as a tv. The black screen was broken. The tv was left here when we bought the house. I took out the black screen and will be using it as a light for my electronics bench in the garage. It turns on and in about 15 seconds it will turn off. Would this be the same issue you described in the video? Any help would be great. Oh it does not power on and off. When I turn it on in 15 seconds it turns off.

Great job sir...

Hey hey! :-). I have a Samsung Smart 3D tv model un46f6400 that power cycles, won't stay turned on. Power supply when unplugged from mainboard, works fine, lights up backlights n all. Plug mainboard back in, cycles with 5 flashes. T-con, plugged or unplugged makes no difference. I did check the cable that runs from the power supply to the mainboard and it's fine. In my head, this all tells me it's the mainboard? Or is that too obvious and it can still be something else?

Great video: Have similar problem on a Samsung PS59D555. Clicking noise no picture. Disconnected Y and X board, still clicking... Attached Y and X and measured STB as you suggest. Should be 5.1 V. When I measure it to 5.3 V the clicking stops and the TV "boots" and the start image appears on the screen. When I remove the multimeter from then pin the picture disapear, and the clicking starts again. Suggestions? Is it mostl likely the Power supply or the Main board?

i love your channel

Nicely explained, thanks for sharing!

I loved your video! Is is safe to assume that this info is applicable to Samsung Plasma C7000 series?

Awesome thanks!

I never had this issued when I had a LCD, but now I am having a power cycling issue with my newer LED, which was bought less than two years ago. Would the fix for the LCD be similar for the LED?

Awesome!!!

You are Great 😮

This is a great channel for the DIYers. I'm currently trying to figure out what's wrong with my 60 inch Samsung that'll work fine for a while but then turns off and on,just before it turns off it get pixelated. Wondering if anyone else has the same problem

Tampatec, I'm replacing my capacitors however I have a capacitor 35v/1500uF but my capacitor kit that was delivered doesn't have 1500uF can I up the uF?

I have a similar issue with our philips tv's, many of them all doing the same thing as this but with some differences. I wonder if it would still be the same diagnosis, I will use these tips to troubleshoot, thanks. The problem is the tv stays on just fine until you change the channel, then it freezes, picture goes into static horizontal lines for a sec then shuts down and restarts. What do you think about this.

I have a TCL LE55FHDF3300ZTAAA My TV started turning itself off from time to time, then more frequenlty sometimes it would sit a hour or so and then it would work again, then recently a day or so and it would work for a while. when it turns off standby light always comes on. When it does work the picture is always clear no lines or distortion. I've seen this model TV also in a Sanyo with the same boards. Any help if it is the T-con or the mainboard? or at least which one I can try 1st

Check your link for parts for my Samsung UN40FH6030, but all parts were out of stock. Do you have another source I could check?

Do you have a good source for capacitor kits? The kits on eBay don't include the one I need. Seems crazy to pay for shipping from Digikey for a single part, and in any event, they don't even seem to have the one I need 450v, 470uf, 35mm diameter max, 26mm high max, radial lead, electrolytic.

hello!I have a Samsung plasma ps60e6500.do the same as in your clip. Rarely starts and stops after 1 minute. Then do the same as the clip. of can u help me pls. Hear back three blasts in succession and then LED lights blinking.thx!!!

Really appreciate your videos. I need help. I opened up my Samsung expecting to see bad capacitors, but they are fine. problems first started with the dvd player not working using the side inlets, then it didn't work pluging them in the back. All of a sudden we had to deal with a loud, long ringing beep with static for a picture before it would clear to normal. Then it started turning off and on, with the noise and static. I still have a standby light so I am hoping it is fixable. please help.

Did you check the capacitors with a capacitance checker ? Just wondering

think your video is very informative

Mate could you tell me if i measure voltage on power supply board and in the information shows me 5v and I've got 5.35 v is it correct? The same is on 13v . I've got 12.76v. Does it mean that I've got to change power supply board? Please

Hello Good Day. I have this kind of issue, but has a little bit difference. It has a loud sound in a Samsung UA65NU model here in the philippines but only when i turn off the tv. I already tried to replace the Power supply but the sound is still present. I also tried to replace the Main Board but still has a cracking sound. Is there a chance that the cracking sound is coming from the display itself?

and this switch on and off awesome

good video

THANK YOU! Video and Website solved it! Put in the new power board and good to go. Probably could have changed the capacitors for cheaper, but the board was easier!

Good work

WHAT do I need for Samsung model-LN40A500T1FXZA...line thru middle with inverted picture( as above so below) so to speak..a light tap used to fix it!! Is there a replacement board from shop Jimmy for this?? I really appreciate your videos!! I have a video out as well- VW42LFHDTV1OA hummed then went completely out! Plus HDMI port out! Any help appreciated!

hell ya man you saved my tv

great videos now I have a question for you I have a 55 inch samsung 4k curve is a 3 years old and when I turning on just click and have no picture and sound do you have any idea what is the problem I really appreciate

What do you look for if there is no stb or standby indication? Just a list of 13v , grd ( which seem to be ground) , od on/off, ps on/off and blue on/off.

Hey Tampatec. Love the Videos, very informative. I have a Samsung UN46D6500vfxzc TV here that is doing something similar. The TV is rebooting it's self, after about 5 minutes or so. 2 things to note. 1. Before it happens, the remote stops working, as do the input keys, sometimes 30+ seconds before it reboots, ( IR and input board is connected off the main board), and 2, the clicking is cumming from the power supply relay, That maintains 5v. Everything else goes to 0 when it reboots. This tells me that something is 'telling' the TV to reboot. From what i have read, this is a very common problem with these Samsung smart TV's. There are no bulged capacitors on the PSU. Do you have any recommendations, short of replacing the PSU? Thanks !

Great explanation and advice, thanks!!!

So if you’re getting clicking coming from the power board but a fairly steady standby voltage then it is likely the logic board and definitely not the power board?

Great in informative video👍 my standby light is on so I think it's a capacitors like you said, and I was wanting to know if you have a video to change out/replace the WiFi ,as mine isn't seeing the router? Thank you

You should make clear whether you are talking about STDBY voltage OFF or STDBY voltage ON as I have steady voltage when the TV is off which you seem to be showing but that voltage fluctuates when ON so now this video has confused me about whether I should be focusing on the Main board or power board. By this video, it would seem that only OFF is the test for steady STDBY voltage then you automatically move to replace the Main board. Is that the correct take away from this?

Hello first I would like to say great video. I have a LG model 60px950 and the problem is when I power up the t.v. I have a black screen and no sound. So I tired to bring up the menu with the remote and the only thing that happens is that the light flashes on the bottom right corner. So I see that it's doing something but still no picture or sound. I removed the back panel and check the fuses and the caps but they all check out good and the rest of the boards so no signs of damage. So any suggestion would be appreciated.

Oneloverecording had posted (below) to hold the power button down for 12-15 seconds to "reboot" the system. I was all set to replace boards and I tried the push and hold on the power button. Amazing, it acts like a brand new TV. I understand "rebooting" devices. Had to "reboot" my chromebook as an example. Thing is these companies don't tell you how to reboot or when it might be necessary to reboot. We live on the top of a mountain and sometimes lightening gets a little close in T-Storms. I suspect we had a close strike that made things a little wonky. Its happened here before with sensor devices, even a lightening protection device I had on my computer. After doing the 12-15 second reboot the TV is working perfectly normal. I suspect now that some people might have replaced power boards that didn't need replacing, only needed to be rebooted.

Hi mate i have a samsung tv that won't turn on, the caps are ok the the ic that is located on the power supply has blown and i can't find the replacement part. i can get the last few numbers but was wondering if you could tell my the numbers that are on your ic please, it is located @ ics801. Cheers

Hey man I have a Samsung UM55ES7500Fand I swapped my power supply board and the Tv turns on.. But the power plug inet faces straight out and makes It so the back tv panel doesn't close.. All my Capacitors look good to me.. and just clicks.. with old board.. Can you show what I should swzp from the board I got..?? My original was a BN4400523A and the sent me a BN4400521A...

Hi, i have a samsung plasma, Yesterday night it turned off by its self and it's standby light like keep turning on and off ever since.. it is as if you are holding the remote control and keep pressing the power button in order to the TV on and off. what do you think is the problem ?

nice needed that what anout smart tvs with the same issue i have a 50 inch smart tv by samsung

thank you. good

Nice fix.

hi . i have 100 tvs at a hotel that i work at lg tv 43lv560h with the coax cable conecter puled off the main board can this be fixed. i have 2

Is tested all my capacitors and they were good. I even replaced two that appeared suspect as well. My TV still clicks on and off, any suggestions? Thanks.

Thanks…. 🙏🏼

Is it the same for plasma tv? I have an lg42pj350-ta.. it clicks but dont start up. Has standby voltage 5v. But it doesnt load the screen.

Hey Paul, I have a weird issue here. I have a samsung un50nu6900fxza and it was working great until it just started switching on and off. The standby light kept flickering. So I went to lift the tv up then realized it stayed on. After a little troubleshooting I realized that if I disconnected the ir sensor the tv stays on. Any thoughts? Thanks in advance.

Hi cheers for the video I have a Samsung le40r74bd doing the exact same thing but I'm.out of knowledge and ability haha what fixed this one? Capacitors seem ok although not tested with a meter. Standby light on turns on with image then goes off straight away...HELP please....any help appreciated mate

Any ideas if I've swapped out the power supply board and the main board and problem continues?

thanks!

Hello thanks for the information can u help me I have a Samsung led HD TV when I turn it on the picture and everything works fine it then flickers and gos off I've opened the back and where the capacitors are there's a buzzing sound coming from that area would it be bad capacitors thank you for reading

Is it the same fix for a Samsung 3-D Blu-ray DVD player that powers off & on continually until the power cord is unplugged?

nice video

I changed the capacitors and the stand by power is still fluctuating while clicking, should I change the voltage regulators now or go to the logic board.

I found a quick fix that helps for a short period and thats to hold down the power on button on the tv for about 12-15 seconds and it will boot into shop mode.

you don't even know what you do, for some of tech cause some of kind of tv's more issues than the CRT TV's so thank you for your video. I also need your help please.

Hello, I have a samsung tv ln52a750r1f, it turns on for a few seconds then off for another seconds and same thing all over and over, I already change the capacitors all of them but the problem continues. Do you think it's the main board?

My Samsung UN58H5202AF isn't really clicking on and off but it appears to be stuck in a reboot loop. I will turn it on and see the Smart Tv logo but then after a minute or two it reboots again. It also gets to a point were the remote is non responsive as well. If I want to change the input source or try pulling up the menu I have to do it right away. However, the screen usually goes a bit garbled and then shortly after reboots. I called Samsung but it was 16 days past it's 1 year warranty so they won't help me. It's a tv in a room where we hardly watch tv so it seriously only has like 40 hours of watch time on it. Should I just try a shotgun approach and order the repair kit for $59.95 from shopjimmy? I do know how to solder and change capacitors etc... if there is a cheaper and easier solution. Any suggestions or tips would be appreciated. Thanks! Robert

Good video but having watched it and done some tests on my Samsung UE40D5520 (which yesterday went into a continuous reboot loop) I have a query: If I disconnect the cable between the power board and the main board I get good stable continuous voltages on the 5V and 13V outputs. However, when I reconnect the two boards together I get cycles of voltage drops to zero on 5V and 13V pins. So...... my question is...... would it be the power board or main board at fault? The power board capacitors all "look" OK - and are mostly glued quite firmly in place, and there are no signs of heat damage on the main board chips. What say you?

my tv is clicking i changed the caps that looked bad and still doing it, the standby led is also blinking as it clicks on and off isit more caps or the regulators or logic board or all ofit yu think?

Hey there, do you have a local phone number to call to troubleshoot? I've taken apart my Samsung HP-S4253X/XAA. No capacitors are blown upon visual. Fuses look ok. The actual clicking sound, which no one actually mentions, is coming from the Power Board, specifically a MOSFET on one of the voltage regulator. Does that mean since the sound is there that that's where the issue is? Or is it cutting off there by design? The clicking sound, however, doesn't appear until I plug in the Main board though. So, what the next thing in troubleshooting? (Couldn't get anything from my multimeter although I don't have those fine tips.) Thanks man.

have a black screen with a UN32EH4003F I could still see little of picture really really dim , my led light is black, if I press the power from the remote the led flash red what it could be

Hi my tv makes a humming noise which comes on for a few seconds then goes off again, and then starts making the humming noise again any ideas mate thanks

Hi,I have a problem with my Samsung ps50c6500 that would keep clicking and would not start I believe it's a common problem do you suggest that what you have shown in the video will be the causes ?Thanks Mr T

yeah i fix tvs too, thats what i do , actually i fixed my own tv ,LG 48" same problem,
