    LG 42LM620T No Power

    LG 42LM620T
    EAX64427101(1.4) LG P/N: EAY62608901, POWER BOARD
    No power, main fuse blown other two fuses ok
    Little cap C614 in picture burnt but still reads the same as C603
    I can't see any other obvious damage on either side of the board
    Can I replace the cap and the main fuse or is there something else I should be checking. Any help would welcome.

      Check that the mosfets next to the cap are ok and not shorted, if they are ok, replacing the cap and fuse may be all that is required.
      If the cap is a 1Kv, replace it with a 2Kv

          I already checked them and all the diodes transistors and the bridge rectifier and didn't find any shorts. I will take your advice and see what happens, it was a free tv so nothing to lose, thanks.

              I replaced the 1Kv cap with a 2Kv and replaced the fuse and touch wood, it has been working ok for about a week now, I will update if there is any change. Thanks for your help RJ

                  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...

                  Microsoft Surface Pro (5th gen) model 1796 - no power
                  by PantherDave
                  Hi all!

                  I'm trying to troubleshoot a Microsoft Surface Pro (5th gen) model 1796 that won't power on. Motherboard model is M1007506-015. My priority is retrieving data, but the SSD is integrated so it looks like if I can't repair it it'll need to go to a data recovery company. I've done a little basic board repair before, but nothing this advanced until now. So please forgive my ignorance in advance. 😅

                  I found the boardview for this laptop in the forums here, and am able to open it on my PC with FlexBV.

                  Asus Probook P5440UF-XB74 power issue
                  by GLISIT
                  Hi all,

                  TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


                  I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

                  A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

                  (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....

                  Carver CM-1090 - Power relay clicking on & off, then fuse blown after 20-30 seconds of power cycling.
                  by beetle1303
                  I gotten a Carver CM-1090 amplifier from a friend who has kept it in storage for decades. Opened it up, thick layer of dust cumulated everywhere. Vacuumed it semi-cleaned, and blown off as much as possible the remaining dust. This is a 220V version.

                  On initial powered up with nothing connected - it works with all the lights and button indicator lit up as pressed, etc. I then powered off, connected a CD player into the CD RCA input and powered it on. It seemed to work for a short while and when I turned the volume up and down to see the the VUs works, the power started to clicked off...
