    Picked up another of these. Just noting that it was the LED driver again. 3.3v was absent from led driver again.

    Not sure why it's so hard to search on bad caps now. Took forever to find this thread.

        See that's the thing. I didn't know I put fxza at the end. If you don't and just put beginning part, it won't find it.

          The search isn`t working for partial filenames. The old forum software search function worked better IMO .

            Got a question, did they change up the how signature works or rename it? not seeing it anywhere.

                This is what I'm saying! How would any random know to search for FULL name or not. It's a bit ridiculous because before I could search for partial and would get hits. It bothers me because I can't find my own topics

                    Indeed, it use to be easy to find your own threads, I don't see it now tho.

                      Sceptre U550CV-UMR 4K LED, Bad Caps on Main Power Board?
                      by Dani_2024
                      Hi and thanks in advance for any input you might provide!
                      I have a Sceptre U550CV-UMRD8POTV83BB 4K LED (this is a dumb tv) that I bought new in August 2021, so It's just completed 3 years.
                      Main power board model: TP.MS3683.PC821 T-Con board: N4TP546UHDPU2L_BO

                      Last Sunday I was watching a dvd and fell asleep for about half hour, when I awoke the tv screen was black and couldn't get the dvd menu to show, so I changed the input to antenna and had sound but no picture, turned it off. I then got online and found this great site! ....read many troubleshooting tips and this...

                      LG 55NANO77SRA TV – Menu scrolling by itself even after removing button board (Main Board EBU66792103)
                      by ygorsan
                      Hi everyone,




                      I’m looking for help with a persistent issue on an LG TV model 55NANO77SRA, which uses the main board EBU66792103 (also used in LG UQ80 and NANO75/NANO80 series).







                      🧩 Problem Summary:
                      • The TV keeps scrolling through the menu or selecting items by itself.
                      • I removed the physical button board (the entire panel with power and volume buttons) and also disconnected the flat cable (CN202) from the main board.
                      • The remote control is not in use (batteries removed), and the TV still shows the same behavior.
                      • I
                      ...

                      Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
                      by Asraf Atb
                      Hi everyone,

                      Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

                      Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

                      I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

                      Compatibility of main boards between different variations of samsung MU6100
                      by JSin21
                      Hoping someone here could possibly help. I have a few questions in regards to compatibility with main boards. But I'll give a quick short run down on what's going on first;

                      I have Samsung Smart TV UA65MU6100WXXY version DA01

                      Now years ago it started intermittently playing up after a lighting strike. Lighting hit the block of units i was living in at the time. Ever since that night the TV started having a mind of its own, It would randomly turn itself off or on, and all inputs stopped responding like HDMI, aerial, but USB still worked. Anyway, over the next few months...

                      Acer TravelMate P214 - N19Q7 main power rail shorted to ground
                      by mkdj
                      Dear all,

                      I have taken out the motherboard of a Acer TravelMate P214. There is a short to ground on the main power rail (19V). I don't have the schematics or boardview for this board (DAZ8IMB1AA0 REVA). But I have found 4 MOSFETS close to the main power rail : 2 N-Channel and 2 P-Channel.

                      I have checked resistance across each of the 4 MOSFETS. I have the following readings:
                      Both N-Channel Mosfets: nothing odd

                      P-Channel MOSFET number 1:
                      source - drain : 117 kOhm
                      source - gate: 96 Ohm
                      gate - drain: 117 kOhm


                      P-Channel MOSFET...
