Occasionally when turning on my Vizio VO370M the screen is very dark. If I turn it off and then on again it seems to be okay. Seldom happens when it has been on for a while.

Hi
Thanks for using FixYa. Hope you already know that this cannot be corrected through the MENU options. To resolve this issue you'll have to open the back of the unit and check the inverter board which is the power supply source for the backlights. The issue can be a bad inverter board and/or the inverter board is not getting 20vdc from the power supply maybe due to the connector that has gone bad/loose.All this is only recommended to be done by someone who has electrical expertise and knows about the internal circuitry of the unit. Please accept the solution if the issue is resolved or post a comment for further assistance.

Thanks
Rylee

Vizio vo370m will power on then turns off log turns red then yellow why


sounds like the power board needs to be replaced. stand by the TV when you turn it on and listen real close near the top where the vents are at to see if it hums. also look in the vents to make sure the backlighting works. if not start with the power board. one other trick is to turn off the TV and unplug it. hold the power button in for 30 seconds or more the plug it back in and turn it on. If that does not work replace the power board

I have a VO370M vizio hdtv that shows no screen, i changed all inputs, what will fix it


You probably have bad capacitors in your power supply. 2 1000@16v caps should probably take care of the issue. 195 general repair cost. Otherwise, if you look closely, you may have a bad inverter panel. 225-280 dollar fix.

You should definitely return it. It is most likely due to backlight malfunction and or backlight invereter malfunction. Either ways you should return it and demand for a replacement if its under warranty.

My Vizio LCD TV screen fades to dark. Sound stays on.


I w having this same issue when watching a Blu-Ray disc. I found it to be dependent upon what picture mode the TV was set to. By this I mean certain picture modes would cause the TV to dim during dark scenes of a movie. Changing the picture mode helped a lot.
