    Hi,

    Code main board is 715G9500-MOA-B07-0H5K

      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...

      (SOLVED) - ONN 100012588 No Power, Then Rebooting After Main Board Change

      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....

      Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
      by Tynan Dill
      I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

      Upon bringing it home and plugging it up, it showed a standby light.

      I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

      The screen seems to blackout and stay black, but with a flashlight I can see the display.

      With my Playstation 4 connected via HDMI, and running a game I can hear sound.

      Hisense 50r6- no standby, no power, bad main board?
      by LemoneyF
      Hi all

      I have a Hisense 50r6 that quit suddenly, immediately after turning it on. It no longer shows red a standby light and will not turn on. Completely dead.

      I have tested the power supply and found the following:

      363V and 373V across the input caps

      bri- 0V
      ana- 0V
      vamp-17.03V
      vamp-17.03V
      stb- 0V
      12V- 9.3V
      12V- 9.3V

      To the extent of my knowledge (...not far!) these numbers are normal for a Hisense power supply in a standby state, though I would like some confirmation that 9v...

      un60j620dafxza - Samsung No Display Problem
      by stylishconsultant
      Hi All,

      Need help.

      I have a samsung un60j620dafxza led tv. When I plug it in it has no display, no sounds, and no standby lights.

      So I opened the tv and disconnected the power to the mainboard and the backlight powered up. This according to many people says that this is a mainboard
      problem. I checked the voltage coming from the stb and I read 1.3 volts on pins 1,3,5 and 7 which are low volts instead of 13 volts which i think the lcd panel
      might be drawing too much power from the power supply that it prevents the right voltage going to the mainboard....
