    Probably tomorrow or Friday depending on when I have time. My TVs symptoms are slightly different from yours so can't guarantee that what fixes mine will fix yours but it seems those caps are the known issue. It's prob not in his interest to tell you what the fix is before you pay him I guess.

    If you do go for it I'd be very happy to know what changes he makes. I'd guess he'd probably use the surface mount caps rather than the through-hole ones, so the board might not look any different to the eye.

      Hey Zelig, any updates? I sold the one I fixed to a guy who immediately cracked the screen while trying to mount it on his wall. So if you need a working main board I've got one, with troublesome caps already replaced.

        Sorry to drag up an old post but I too am looking for this board if anyone still has one for sale? If not I have the rest of the TV for spares if anyone needs anything before I tip it?

          I have an LG 37LF65 which developed a terrible flicker.

          It would be fine for the first 5 minuets and then start to flicker, the picture was so bad it was completely in unwatchable, but after 20 mins it would settle down. This 20 mins soon became an hour which was clearly no good.

          I found one visible bad cap on the power board, as is best practice I replaced the lot, about 22 of them, this cut the flicker time back down to twenty mins but clearly wasn't the problem.

          I moved on and took tn245's advice and replaced the 6 caps marked c901, c954, c533, c970, c975 and c 915 on the main board.

          Voila, no more flicker.

          Thank you guys,

            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.

            Sony xbr-65x900c main board issues?
            by jb_Bak
            Hey guys great forum glad to have found it. I bought a Sony XBR 65X900C cheaply because it didn't work. No signs of life at all not even a light/led. All I hear is a brief high voltage sound when I throw the power to it.

            Didn't see any obvious signs of damage so right away started checking voltages. This is what I see:
            Power Board Connector that goes to Main board
            CN6401
            Pin 01 NC
            Pin 02 NC
            Pin 03 "BL_ON": 0V
            Pin 04 "N/C"
            Pin 05 "STBY 3.3V": 3.5V
            Pin 06 "GND": N/C
            Pin 07 "AC_OFF"...

            (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change

            ONN 100012588
            Issue: No Power, Then Rebooting After Main Board Change

            Short answer: replace main board and power board
            Technical answer: replace main board and Q306 & Q307 on power board.

            Long answer:

            TV wouldn't turn on. Power switch was fine which means the main board isn't processing the power on signal. Replaced main board. TV turns on now but randomly reboots. Bad main board? EEPROM? Tried to pull main board and got a shock touching the corner of the board. That's weird. C334 (450V 10uf) capacitor is still holding a high charge....

            Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
            by cheeky2
            I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
            Obviously the same LVDS connector for the screen connection...
