    EMERSON LC320EM8A peeled a cap off the main board...

    this tv worked fine, just had a cracked screen. so i was going to part it out and put it on ebay...
    i was trying to get the metal shield off the Main board when it snagged one of the capacitors and tore it off.

    im not even sure what kind of capacitor you call these, and are they easily replaceable?

    can i replace it with a regular electrolytic cap and just solder the wires to the pads, or do i have to get this same "can style" capacitor?

    can i buy the replacement cap from this forum?

    oh and what would probably happen if i tried to use this board like this? would it just not work, or could it actually damage something worse?

    thanks in advance for answering my noob question!

                  Looks like it to me.

                  Going by the photo, it looks like it's doing supply decoupling for the tuner module. I don't know if these typically require low ESR capacitors or not.

                  But... in a DishTV T1020 STB I just recapped, the tuner module had JFD TM series capacitors next to it, which are a Low-ESR series. I replaced them with Low ESR capacitors. The thing has been working perfectly for a couple of days so far.

                  Even if it doesn't need Low ESR, I can't imagine using Low ESR there would hurt anything.

                          It doesn't matter. Just about anything from a reputable manufacturer will be fine. I would recommend a cheap low ESR series for convenience's sake - then you can buy a few and have some spare.

                          For the record I used Rubycon ZLJ in mine - total overkill but I was already buying some for the PSU so it was easy and cheap to just add 2 more to the order.

                              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 ā€“ Menu scrolling by itself even after removing button board (Main Board EBU66792103)
                              by ygorsan
                              Hi everyone,




                              Iā€™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).







                              šŸ§© 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:

                              Pin 03 "BL_ON": 0V

                              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....
