It usually takes a second for the TV to fully startup, then the backlights turn all the way up.

@surefixtech yea but,my tv stays dimm for hours then goes bright ones in a while, then sometimes it stay bright wich is good.

@rayhernandez6784 in that case, your backlight is dying. If it has a plastic back that looks like the one in this video, you might want to replace the backlights before they burn the diffuser.

@@surefixtech is that expensive?

You’d have to check with a technician, labor costs can vary. Are there any bright spots or yellow at the bottom when it turns bright?

I don’t think it’s lazy. It’s how I do it. I fix this same problem so often that it’s the quickest way and safest for the tv. Also I’m bad at soldering :p sue me

@ztronixz2236 oh also what usually happens to this model is the filter capacitor blows, takes out the mosfet, which then blows the fuse. You can just remove the cap, then replace the mosfet and fuse and it’ll work (:

I’ve never seen that to be the case for Samsung or any other tv for that matter. It’s usually a capacitor that blows and then kills the mosfet, which then kills the fuse :p

I got a little creative, I’ll release the full video soon 🫡

The panini maker is essential, it’ll be in the full vid though ! (;

Haha good point. Of course I have to replace the fuse, my phrasing was more of a segue into the footage. Story telling :0

@@surefixtech gotchya I was so confused lol

lol yeah, that would be super convenient tho if it could fix itself after the short is removed. There’s probably a circuit like that out there that I don’t know of yet

Thermal packaging paper sticker. I ripped it from an Amazon delivery box :p

So I tried to check the resistance with multimeter across multiple capacitors on the same side of the board where you showed the bad one. Most of them beeped. Does it mean all are bad? I disconnected the ribbon bale and half of the tv showed white screen. How do I go about narrowing down the issue before breaking capacitors. In you case it was single I doubt the tv will work if I remove more then one.

@rkbest9783 the proper way is to inject voltage into one of the bigger capacitors, like I showed in the video. You can also desolder the one I showed in the video, and just test that one for a short. If it’s fine, place it back and check the other one. In my experience, it’s one of the two side by side that I removed.

@@surefixtech when you apply voltage, are the cables all connected. Also can I use a 12v power adapter as I don’t have a adjustable one like yours

@rkbest9783 @rkbest9783 Good question! Unplug everything. Unplug the panel from the tcon, unplug the ac cord from the power board. Also, be careful. I wouldn’t recommend using anything but a variable power supply specifically made for this purpose. The safest way to determine which capacitor of the two is bad is to desolder, test for short, and then repeat if the short persists

It’s a custom workbench hand made. We use hinges and sliding tracks to lift the tv into place

It’s an issue with the panel as far as I know. Replacing the ribbon won’t fix it

Unfortunately this issue is extremely common with Samsungs TVs, and it will always happen eventually. Sometimes you can cover another clock signal and it will work with worse quality. And if you reduce power consumptions for the tv, you can also slow this aging.

​@@surefixtech mine only lasted from November to this month its a 2023 UHD RGB Led screen i forgot the series but i hate the Smasnug tvs

I know :( there are 3 major flaws with Samsung TVs: backlights, panel, and power supply. Every day I fix one of those 3 issues

The misfits is a band from the early 80’s hardcore punk movement. Oh you mean mosfets? Yeah, those are metal oxide semiconductor field effect transmitters. Gold star ⭐️

Yes!

I'd tap that.

In a lot of TVs yes, it’s a firmware issue often times on the NAND or EEPROM. But this is a very common issue on Samsung TVs. You can do a search on KZfaq for Samsung “tape method”

Thanks for the comment! I’ve heard about the CKV lines before, and I totally know what you mean with the color issues. It’s very hit or miss for me at the moment. Do you have any tips to share about this topic?

That’s awesome! I’m glad I could help save your TV and your wallet 😁

Of course. I use the following things but it’s also important to have a flat and relatively soft area to work, free of any objects that could crack the screen: - Screwdrivers (rigid model R8224) - Backlight tester (TKDMR model TD3H) - Spatula pry tool (ACE hardware) - Portable soldering iron (Lenove 926 LED III) set at 360 - any 3v LED backlight strips for repair, or search for the tv model number + “backlights” on eBay to replace the whole set - low melt solder, enameled copper wire I think that’s everything (:

@@surefixtechWhat adhesive did you reapply when putting screen back on?

@claytongish9355 some TVs like this one don’t require adhesive. Very few, like the unibody bezelless Hisense TVs that I’ve made a video on, require adhesive strips. You can search “adhesive strip for TV panel” on eBay, I’ve only found it overseas. It’s a double sided, black adhesive tape. But you can’t use iPad adhesive strips for example.

It’s possible that the power board you replaced it with has the same issue, as this is a design flaw from Samsung. I recommend testing without the main board plugged in, to confirm if it’s the power board. If the screen stays lit up (backlights) then try the main board. Hope this helps (:

The easiest way is to buy a Roku box or fire stick (:

That is really awesome! Do you mind if I steal your idea for the next video on this topic? Such a creative solution, I love it!

Thanks! I plan on making another video with diagrams for this particular tv. But for this specific board I tied the 0ohm resistor before the chip to ground.

Thanks for watching ♡

I’ll admit the video is a bit silly. But the tv works after a successful repair and THAT is not a troll (:

That’s a good looking tv 😄

Yes, this can sometimes be a problem with the panel. Known as a short panel. We have videos on the Hisense 58R6E3, which has this problem a lot. If it’s a different model, this solution also might work. But it sounds like a short panel Good luck!

The panel is fvked , if the tv is old enough it's more effective to buy a new tv instead of repairing it

@nakshtra604 Panel issues can be repaired, we have some videos of this on the Chanel. Stay tuned because we filmed a really cool panel repair video yesterday!

Yeah! Honestly the most common OLEDs we get in by LG are either short panels (haven’t found a reliable fix… yet) or a simple board swap. I’ve run into very specific cases, such as a one of a kind transparent oled that we scrapped together a power supply for, and some other one offs. I’m excited to make more videos on OLEDs as I learn (: thank you for the comment, and stay tuned!

@@surefixtech Fantastic thanks for the reply. Also for your own entertainment room, Do you mess with Qled or Oled?

In my own home I use an LCD. Although I don’t really watch television so often, ironic I know :p

I respect that! There are a few ways to find a panel: You can open the tv and look for the part number, search for it online. It will likely be very expensive and shipping can be a problem. You can also look on Facebook marketplace or something like that for someone selling a broken tv that you may be able to harvest the panel from if it’s the same model. You could also check with a local repair shop and ask if they have the panel/tv in stock. I hope this helps (:

🙌 you get it!! I do think component level repair is cool and worth doing, we just happened to have this board in stock to replace. Thanks for the comment 🤘

I know what you mean. We just happened to have the board, but you can find it online for less than $50. We do have some component level repairs posted on the channel for reference as well. I would also like to go more in depth with a longer video on power board repair, so stay tuned !

That's a no brainer

@hero4life313 I’m actually in the process of editing a long form video about a power board repair for an OLED LG tv… Component level repair 😎 watch out for sus MOSFETs

Backlight repair is the staple of tv repair economy, keep fighting the good fight, friend (:

Thank you for the sincerity, and I agree. A lot of creators on here who have inspired me to make videos have also really instilled in me the importance of right to repair. This will come in the future, so stay tuned (;

@@surefixtech You are quite welcome. 👍

That’s what we did, you could also just order the power board by part number for around $50 :0

See I’m glad someone understands 🥹

This was a very long time ago so I don’t remember exactly, but I can tell you what I would do today: please be safe working on devices with high voltage. After opening the back and discharging the power board safely (if you don’t know how to do this it’s better to be safe and don’t attempt this repair as OLEDs carry a lot of power), I would check the power board main capacitor, and check to see if the main board is getting voltage. Other than that, please be safe and take it in to a shop if you are unsure. Alternatively, order both boards and return whichever one you don’t need.

Thanks for coming in! We love all things nerdy 😁

Quizás debas reinstalar el firmware para que quede como cuando venía de fabrica

Im a real boy !! 😼
