You sir, are the man! Mine was behaving exactly like the second TV you had in the first video where it inexplicably started working again, and the boards also tested very similarly. I suspect I'll be changing the strips sooner than later anyways but I'm going to try and ride this out, at least until I have better means of getting the panel apart. Thanks for the very detailed videos. (UPDATE: It died again after a few days, but I noticed the picture had a blue tint and was dim, so that indicated the backlights were dying anyways. Bought some suction cups and swapped them out in the dining room. Took about three hours start to finish but it's back in action!)

There's no schools for TV repair. Watching videos like this and learn by doing. He goes over toubleshooting and soldering.👍

This video is the BEST! I was able to fix my TV (same model) in about 2 hours with some replacement backlights I found online. Same exact issue - no image, 6 blinking red lights. Thanks for making such a thorough and detailed video, and THANK YOU for not cutting out the mundane things! You saved me easily $1000+ for a new TV.

Man, two words.. THANK YOU. Figured for $50 (LEDs and cheap suctions at Walmart) and three hours later with taking a break, it’s working again. The hardest parts were: 1.) that blasted tape at the bottom, 2.) putting those plugs back in after replacing the strips; and 3.) replacing the black tape strips. Nothing you can’t figure out, but regardless…. Again, thank you.

That's what i call precision work, apart from the audio going low at times, excellent job/video bigdog😀😀

Thank you for sharing this. I'm sure there was some aggravation trying to figure this one out. I think it's nuts how these name brand companies keep trying to make it either harder or more expensive for techs to repair sets. Shame on them. I love the advances in image quality but when it cost a thousand or more for a 5 year TV before the lights or something else quits .... guess I'm old school, it seems a bit greedy. I guess that's why Sears went out of business - they stood behind their product. I have a Toshiba 52" DLP that I've spent $160 over the last 20 years to replace the bulb twice, which takes about 5 mins. Maybe not the best quality picture but I'm not changing backlights every 5 years. Yes, it was more expensive than the same size TV you can buy today for the the price, but a lot less to maintain. Great job security for us tech's but all they really want to do is sell you another set. I get that technology changes but people need to realize that electronics can be repaired for less than having to buy new every few years unless you need the best. Todays electronics are built to last short term due the fact that technology changes so quickly. Inherent obsolescence. There's nothing bad about repairing what you have. Go green. 👍

Just did mine. Great tips on how to get it apart. Mine would flash/sometimes work. After getting it down to the leds I just exposed where they connect to the main power. Accidentally hit one of the connections and it shut down. Found that it was just the connection. Put it back in tight and now working. Let’s hope that was it! Check them connections people!

Learned something again. Thanks BD!

NIce find bro, I have no doubt that came from all those years working on cars. I know I worked on cars for 40 years and you just know until you investigate and then it's the AH HA moment. Love your channel just keep doing what your doing except that music some times make me wanna scream. LOL.

Thanks bogdog, you have really helped me. I loved the elimination (diagnosis) of the boards in part 1.

That's what I did with the 39" Insignia. Changed em all with brand new & 4 years later still working great.

Brilliant video! for some reason I was captivated like a Netflix documentary. I actually have the same problem with my KD55x8509c .

Great Video bigdog ......... always something new to learn from my favorite teacher.....Thanks Again ! Dan in WI

great job dude. watched both vids. as a hardcore diy guy Im definitely subbin this channel

thank you for showing it like it is ,i have a 70 inch version and had the blue screen and changed the led strips, no-one shows the little screws or the hard/awkward bits like you did or that i found , pulling the white stoppers hurt the finger nails and replacement was a bit hard , great video showing care taken ect cheers many thanks woof woof

Your right it's hard work... led replacement is the majority of repairs now.. especially the TCL televisions

Skilled man there!

he is the best hope he can start a course of fixing and troubleshooting TV

great job bro

I'm curious about pulling the diodes off the others and trying the strips without them.

Thanks Keep inspiring. Greetings from Venezuela 2022

From 🇸🇬 Singapore. Great work!!Appreciate your thoughts on viewers about subscribing. But I do appreciate your enthusiasm and your intention for non- tech savvy people..who are interested to do similar work..maybe to help other etc. So I subscribed!!!

Sony make the best Tvs but put cheap diode on the backlight strips or individual Led lights. Thanks again for sharing BigDog king of backlight repairs... And don't forget to turn your bright·ness down to 50 % on your Tvs...

Congratulations

Good fix.. rouku tv are also notorious for led failure

I’m curious as to what was the problem with the identical tv and it’s intermittent failure? If issue is intermittent would cleaning contact points be advised as first attempt to resolve? I read that if (same as here)Sony tv sits unused for months it can also fault out upon reuse? Which is why I’m asking about contact points. My tv sat unused and now is 6 blinks. I don’t have the testing equipment to do the troubleshooting. Likely not the understanding necessary to execute either. Hate to add to landfill because replacement cost is equivalent to the repair. Thank you for the thorough and excellent tutorial. Your an excellent teacher!

Actually that makes sense. Especially since LEDs are diodes. Use a stronger LED and eliminate the zener diodes. Probably a lot of TV from this year having the same problem.

B.D. Very weird problem ! 1st time I've heard of diodes on the LEDs.

I have done about 5 of those and would never return this model to the customer with a single strip changed (always full set on this one). Diodes is one issue; continuity across strip junctions is another…) Either way it’s always a full set on this Sony Junk. Cheers!

Hey Big dog, question for you my 2018 Sony 900f had I think the five red blinks was told by two repair people was a backlight issue. Had a guy fix first time I got back had visible tape on the lower side of the screen. I took back to him fixed but now one area kind of middle toward left top seems a little darker. He told me was using Sony parts now nit sure he actually did. Other repair place said 6 weeks to get parts he had in two days...could that be the cause? Thanks!

Hey BigDog8882 where can one get those led replacements?

I have cut the diodes off when led strips don’t work they go short, 😅 Nice find Marc

Looked like the old LCD TV bad backlight invertor issue. Quick flash of light then dark screen.

Were do you find the LED's for this tv? Very educational thank you for your guide on my future project

Nerve racking job with that one but once again it was a bulb issue!

where do you get your leds from? im in chicago too

Hello! Does anyone have the electrical diagram that can help me? Is it possible that it is some component on the board and not the LEDs?

Hi Sir I like u detailed video Thanks I have a Sony Kd-65x8000 Tv N It’s back light is not powering up showing 6 red blinking light. So when I test the BL+ terminal it’s abt 200v constant but the BL- starts with 60over V n the V reading starts to fall . When I disconnect the T-con board ,the tv starts to have sound n no more 6 blinking light Please advise Thanks

Is there way I can contact you, and get you on the phone? I have the same tv. I replaced the led strips yesterday. And now, I’m getting no signal to the lcd.

@BigDog8882 Do you have a link to where we can buy the new LED strips?

Do you ever see this tv with the 2 blinking lights?i only seen one other person ask on the internet and he got 2 different answers..from main board to power supply board

it is best to change all the bars so that they have a new beginning

I Have A Flatscreen I Got From My Neibhor Downstairs & All I Get A StandbyLight So Do You Think It Could Be A Tcon Board Or The Logic Board?

great video, do the suction cups cause screen damage? I read they can leave permanent visible marks in the lcd

Great Videos Sir!! Sadly I have 2 of the same TV's except 70'' version and 7 years old, one with that same 6 red lite blinks, the other one is too blue in color on all channels, and worse if a team is wearing blue uniforms!! And after watching these two videos, I'm out of my league trying to fix them, so off to the dump they'll go😢😥

I have the exact same tv with yhe exact same problem broke my heart im on the fench on fixing it i cant afford a new one

Hi Sir, I have Sony KD-60X690E with 2 red Blinks do you know what's wrong with it? Can you show us how to fix if you have a chance! Thank you!

They sold a Vizio E60-E3 and E70-E3 shared the same screen tcon and the worse version of those backlights that turned blue

Good job. We know that life of the led s 5-7years. Some times 10 years. Actually it calculates by hours. You can find it by googling. I can say that issue the 95% of led tvs which I fixed was led strips . I have same model tv with same issue, and I ordered led strips few days ago and found this video right now. It could be power board 4% and signal board 1%.

I see it in Samsung but first to see in Sony . led bulbs are only safe with a series resistor due to wattage and heat it was prevented. It is 4:30 am in India

Sir, I've inspired a lot from you about repairs of LED TVs Currently I'm facing an issue with the 6 red blinks. Before this issue I was getting 19.5 Volts clear ....but now not getting it Any short circuit issue? Please guide Make and model is Sony KDL 40W650D Thanks

The TV I Have All I Get Is A Standby Light So I Know The Power Suply Board Is Ok So I'm Leaning Tward The Logic Board & Tcon Board.

👏🏻👏🏻

Check All The Boards The Tcon Board & The Logic Board

I replaced all the LED strips a year ago ... now I have the same problem once again ... same TV

I have the soluton

Hi Big dog, thanks for your great video, I am located in Australia, my tv is KD70X609E, I can say my tv is just exactly the same to yours on your video. I followed all the steps, I can see the six red light blinking has gone, the screen turns on (as i can see the change from deep black color to dark grey or dark blue color. but I dont have display (no fonts, no information, no sony image at the beginning) do you think it could be any wrong connection or damage of ribbon cables attached to the black screen to the chasis circuits? I am in the dark mate, i hope you have some free time to read my message in give some advice. thanks so much, and congratulations for your great content.

Definitely had to change all the strips anyway, the color of light from the old vs new was not exactly the same and would probably show up in the image.

Do not remove the led strips, in fact they all al working so look at the power connection t the led strips.

Diodes faulty, new LED strips required, change all of them got it ,not techy minded Big Fella plus I got fingers like sausages so me doing the repair aint happening , the vid shows me what the problem is, the info given, gives me a chance to talk to the repair guy as if I know what Im talking about . I had 5 years warranty when I bought my Sony TV ,Im well pissed of at this fault , especially when the issue appeared 3 months after the warranty ran out . After watching your vid all I gotta do is cost the repair against another TV weigh it up, I looked at the price of the LED`s so its his time and the pick up and return ,how long did it take you to do the the repair by the way .? I went out looking for another 55" TV yesterday , Samsung, Sony, Panasonic , LG which I liked @ £1499 Oled,Qled Ultra, HDR 4K ,8K, it was doing my box in . Will tell you what the bill is later on ,many thanks, great video !0/10.

Would anyone be interested in spare parts for this exact tv? Contact me, I have two of almost everything this tv needs except the leds and the remote. Or, Bigdog?

the light produced by leds is not white

I have the solution

As Long As All Of The Led's Work I Wouldnt Replace Them

I think I will build a table that spins like a lazy Susan with locking positions.
