    Visio VU42L FHDTV10A voltage to main board?

    All,
    I have a Visio tv that powers on, with backlight, but no picture or sound and can't turn off with remote or power button. I've seen countless posts and videos pointing to bad voltage regulators. But what has me puzzled is that on the 2 fuses where the power comes onto the main board, I get a reading of 19.25 and 8 volts. Everything I've seen indicates it should be 12 and 5. As a result, the readings I'm getting on the voltage regulators is off of what others are posting. Could 19.25/8 be correct? Should I be looking at the power supply board first?

    Troubleshooting electronics is new to me. I'm reading those numbers off both the fuses and the ribbon cable coming from the power supply board. I've got neg attached to the case frame.

    Any pointers are appreciated.

    Thanks.

    Terry

      Think you got lost in the many other posts...Don't be afraid to "bump" up your post..

      Reading this I would say your meter is suspect to being faulty,maybe try to measure a 9 volt battery with it and see what is gives you? New battery would be best..

          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...

          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"...

          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....

          Hi, this is my personal laptop, which the original board (lets call it Board A) blew up PU8700 (TPS51486), making a hole on the board, i had left the laptop at my desk one day with the battery fully charged and didn't touch it for a week, but when i tried to turn it on it didn't
          Thought the battery was dead, so i plugged in the charger then tried to power on, the power LED blinked once, charged LED still orange, unplugged the charger, plugged in again and I noticed the "magic smoke" smell, so i unplugged the charger, removed the back cover and saw the blown IC (the "magic...

          Is it possible to upgrade from a Vestel 17MB97 main board to a 17MB110 Main board?
          by cheeky2
          I suppose the real question is whether the existing pinouts from ether a 17IPS71 psu are cross compatible with a 17IPS12 psu? If they are then the exchange of the main boards should have no issues providing the screen is compatible with both main boards. Obviously you can change the screen configurations easily enough (providing you have the correct files) for the main board. Why may you ask would I do this? Well a lot of the smart features are no longer working on a Hitachi 48HBT62U main board I wish to give it a new lease of life!
          Obviously the same LVDS connector for the screen connection...
