Working fine then turned off now nothing ,power light and it fades out black screen no sound no back lights 5v on power supply only all other power fades awayen power light goes out.
Do you have voltage (3.5V) on the PSON terminal when you push the start button on the TV...if you don't its the main board that has failed
Testimonial: "I have 3.5 volts and 5 volts nothing else."
SOURCE: Plasma no picture, fades to black from startup logo
UPDATE:
I finally isolated the problem, the problem has to do with the Y SUSTAINER BOARD not receiving enough/necessary voltage when turned on, while initially thinking it was just the yboard was the problem, i replaced the Y sus board with no success, with only further diagnosis, i discovered the board voltages coming from the powersupply, there are 5 voltages that relate to the Y sustainer board, VA, VSC, VS, VE, VSET. they all supply a certain voltages that all have to be supply the correct voltage in order for the y sustainer board to be working, well guess what, the VA line, which for my set needs 70volts, which upon startup quickly drops from 75volts to a jumpy 8.5-9.5 volts, which of course is nowhere near the 70 volts needed, so this quick drop in voltage is directly related to the screen fade upon startup, i found the problem now the real problem is finding a replacement power supply. hope this helps anyone with similar issues.
SOURCE: Vizio 42", have picture for about 5 mins then screen goes black.
also check the power cord wire coming from the back of the tv is loose from the tv side or perfect.
SOURCE: No Screen or sound
there are two possibilities to this problem. First and cheapest way is to replace the main board. Second, replace the inverter board. This is the boards that are mounted vertically on both sides of the TV.
SOURCE: Vizio plasma. screen went black, and the power light went out.
Sounds like the power suply went. I don't know that model off the top of my head, but you might find a replacement here http://www.electronica-usa.com/Merchant2/merchant.mvc?Screen=CTGY&Store_Code=EU&Category_Code=PLA
