Question about Vizio P2 42 in. HD-Ready Plasma Television
Don't if figure! Two months out of warrantee. My picture tends to look like a laptop computer after you've unplugged it from the wall and gone to battery. In the laptop's case you are then running on half power, which it what my tv appears to be doing.
All the colors appear to be correct and present. The picture is just way faded and dark. I do notice some grey/black clouding around the edges as well.
Now, I know that these things have component boards in them. Is this something that I can do? I was an electrician in a former life and have replaced component boards, but have no experience in replacing components within boards.
Thank you and I appreciate your help.
Hello dumbneasy, My names Dave and I can tell you that you most likely have a bad Z sustain board! P/N's: 6871QZH956A or 6871QZH056B 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 just to confirm which one of the two are bad! 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!

Try finding the gamma/brightness potentiometer and turning it ever so slightly, testing each time to see if you are adjusting it correctly. If I'm right, it will be on the same circuit board as the cable tuner. I'm not a p42 owner but my dad has a vizio of another kind with this problem.
