    Re: UN60D8000YFXZC Samsung - not powering ON

    OK, some good news, I hope. I did not have the right SOT-23 3.3V regulators in my stock, but I did have SOT-223 and TO-92. So I used an L78L33 regulator because it was easier to solder, I know it is only 100mA, but so far it worked well. I turned the TV ON for 10 min only, I was afraid that the lower amperage regulator will heat up, but it is not even warm. Do you guys think this will do the job? If 100 mA is too low I could replace it with an AMS1117 3.3 regulator.

      A powerful one is not needed there, since it only powers the micom, so 100mA is enough.

              Help Needed: Samsung UE55MU8000 Dead - Possible Main Board Issue
              by Asraf Atb
              Hi everyone,

              Im looking for some advice regarding my Samsung UE55MU8000 TV with main board model BN94-11606C. The TV suddenly stopped turning on and now shows no signs of life at all not even the standby light at the bottom.

              Initially, I suspected an issue with the PSU, so I took it to a repair center. They tested it and confirmed that the PSU works perfectly, even on other TVs. Based on that, I started investigating the main board.

              I disconnected the main board from the PSU, and the backlight turned on, which seems to confirm the main board is the issue....

              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...

              Samsung UN75RU8000FXZA bad main board?
              by Lee M.
              When plugged in it will click and cycle the BL on and off, no pic and does not respond to remote. When I disconnect the cable from the PS board to the main board and then plug it in the BL will come on and stay on. There are only two boards in this set, the LVDS cables from the panel driver boards connect directly to the main board. Since the BL comes on and stays on I'm thinking the PS board is ok and the problem is on the main board. Should I order another main board or do I need to do more testing? thanks, Lee

              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
              by JDC
              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....
