My Vizio M502i-B1 (serial #LTYWRLAQ...) failed to turn completely on yesterday. Pressing power on the remote made the white light appear briefly however nothing showed on the tv. The tv was then unresponsive to the remote or the power button on the back side.
If I plug the tv in the white light now stays on. There is no screen image or backlight.
Some previous history:
I did have the main board replaced under warranty in 2015.
The sound stopped working 6 months ago so I rigged the tv speakers directly to an external receiver (wasn't a problem with the speakers themselves)
I only have a multimeter to check things with and I am not an electrical engineer although I would love to be. Hoping we can diagnose this together, but please take it easy on me as I don't know much, but will try my hardest .
FYI my mutlimeter is a Craftsman 82351, not sure how effective it will be for all the diagnostics I need.
Thanks!
