      Its probably the main IC under the heat sink that’s the problem.

          Hello,probably,resistance on coil leads to main ic is quite low.
          I don`t have working board to compare the values,maybe it is normal

              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.

              Philips 196V3L monitor power led off
              by mikey5791
              Hi, i was given this lcd monitor last week with the issue of power led blinking. Upon checking the power board, i found 2 pieces electrolytic caps bulged and replaced them.
              Later, when i switched on ac power and detected 5v and 15v dc at output pins. But as soon as i pressed on the front power button, the led on power button lights for 1 second and it turns off.

              So, i tried disconnect the flex ribbon cable from t con board. But all i got is a white screen with nothing on. I suspect there is something short somewhere that prevent the display being turned on. Can someone with...

              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....
