First thing to check is if the back lighting has just failed... Power the set on and looking across the screen can you see a shadow of a picture happening? You might even use a flashlight to shine directly at the screen while you look at it from an angle.

SOURCE: help - 15 mth old 42" edtv "plasma" black screen" have power and sound

it could be 1 of 2 things, the panel could be shorted or the logic main board could be out, you must open the back and take voltage measurements, check the panel voltages and then start pulling the connectors off one at a time, to see if the voltages come back up

Unfortunately if the screen is cracked the only remedy is to have it replaced which will be expensive, therefore it might be worth considering a new TV

Try first unplugging power cable for thirty minutes, then plug back, this will drain power from TV completely and will reset it.

See if it works.

Vizio P42 dark haze when turned on


This is an ongoing issue with the Vizio 42" series. The SMPS power supply has been a problem in all the Vizio models since day 1. We repair these sets and I do not recommend them at all, they are very unreliable. The SMPS power unit is board replacement only at this time and very expensive.
