Viore pdp42v18ha problem - no audio
Purchased about 2 months ago. Do not use the set very often. Used to work but now when I turn on the set, I get audio but no video. I can't even get the TV menu to display which I believe is source agnostic. The only source that I have plugged in is a standard RCA connection (yellow video, white and red audio). I unplugged the set for 24 hours but not change in status. I also tried other sources (HDMI, HD component cables) with the same results.

Take it back to the dealer from which you purchased, receipt in hand and raise a stink.
If the set is under warranty, I'm not sure what sort of technical suggestion one could give that did not involve "getting under the hood" of the unit, which would most probably void the warranty. Thus, the "take it back" suggestion. If the unit is used, or if you just have money to throw away by hacking at it yourself, then I'm sure there is someone on here that will be willing to tell you whatever it is you need to know.
It looks like you have taken the basic steps (tried all the inputs, disconnected from the mains for an extended period) and this didn't work.
