    Maxent 50x3 Main Board SMT Cap in Question

    Hi all,

    First off please excuse my noobishness, and spare me the spankings. I have a Maxent 50x3 I am attempting to repair without destroying. It has some crazy vertical lines in front of the image that come and go but seem to be worse as the board warms up. Pressing on the main board definitely affects the picture. As does spraying duster in the vicinity of this cap. Based on the appearance of this cap would you all suspect it as being bad or does this look like flux either from manufacturing or an attempted repair? Also the paint is cracked a little do you think this is from expansion? Thanks

      Also forgot to include that I have replaced the usual suspect that other threads have suggested with no affect. Just so I don't get references to that thread.

              Ya looks pretty shoddy, but several other joints look cold like that but without any flux residue so I'm a little confused. Do these type of caps leak? There is crusty residue on the board that could be either flux or cap crap.

                  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 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:
                  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

                  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....
