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

@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.

@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 (:

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.
@surefixtech2 күн бұрын
@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.

@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

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.

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 (:

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 (:

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.
