Question about Vizio P2 42 in. HD-Ready Plasma Television
I have a 42 inch viso plasma screen and everything was working well and then all of a sudden no picture. I pulled the back off the TV but i dont see burned parts. Do you know what could be wrong with this TV?
Just had the same problem and determined it was the primary power supply board. The TV has a primary and secondary power supply. The secondary controls the on/off and audio. The primary controls the picture. If this is shot, you will not get a picture but will hear audio. I had to call Vizio and have them send me a new power supply board ($150 + SH). Not too hard to install yourself. Hpe this helps!

Hello, My names Dave and I can tell you that you all most likely have a bad Z sustain or Y sustain board! The good news is that most of the time if either of these boards are bad you will find a blown fuss one them! I have worked on this same model of TV many times! You can lay the TV face down very gently and remove the back cover from the TV and test the fuses on the Z & Y sustain boards to confirm which one of the two are bad!
Z sustain board! P/N's: 6871QZH956A or 6871QZH056B Here is a link to the Z sustain with a picture of the board so you'll know what you're looking for http://www.shopjimmy.com/lg-6871qzh056b-zsus.htm
If you look at the Z sustain board you'll see that there are two white fuses on the board FS1 & FS2 are the location #'s. There is also a third fuse (FS3) it is a surface mount type fuse and can be easily over looked. Just locate the 8 pin main plug right next to the other two fuses and you can't miss it. It's smaller and it will have gold colored ends on it and it to is white with the location # FS3 next to it!! If any of these fuses are blown you will need to replace the board to complete the repair! You will need to test the fuses for continuity with a DMM (Digital Multimeter) Do to the fact that you will not be able to just look at the fuses and be able to tell if they are good or bad!
You'll also want to test the three fuses (FS1, FS2, FS3) on the Y sustain board P/N's: 6871QYH953A 6870QYH005B ! Here's a link to a picture of this board also. http://www.shopjimmy.com/catalog/product/view/id/179043/s/ysus-6871qyh953a/
Two of the fuses (FS2 & FS3) on the Y sustain are easy to find because they are normal white fast acting type fuses! The third fuse is also a surface mount type fuse and can be easily over looked. Just locate the 9 pin main plug right next to the other two fuses and you can't miss it. It's smaller and it will have gold colored ends on it and it to is white with the location # FS1 next to it!
If any of these fuses are blown you'll need to replace the board to complete the repair! You will need to test the fuses for continuity with a DMM (Digital Multimeter) Do to the fact that you will not be able to just look at the fuses and be able to tell if they are good or bad!

Same issue here. I opened the unit up and took a look. I was just given this TV for free by a coworker who said Vizio told him it required a new "powerpack" I'm assuming power board. In any case on my powerboard there are two toggle switches with the labels Standard /Auto and 30v/24v. I reversed both these toggles and on a whim put it back together. So far the thing is working great screen comes on and right now I have it plugged into my cable boxes coax output.

Make sure you have the correct imput selected. If possable check the cables on another tv. Make sure the tv is not in sleep mode. If you try all of these things and do not get any results take the tv to an authorized repair center.
