SMPS power supply for Vizio p42

I have a dark haze issue on my plasma tv as another asker. Do you know where I can locate the power supply board?

    I have sound and no picture. I took the TV to the shop and paid 90 dollars that was to go to the repair. The power supply board is out and VIZIO does not make them anymore. I have bought several VIZIO's since that one 3 1/2 years ago. The one I bought this Christmas will be my last VIZIO. I thought I had a good product. However, a TV less than four years old and very low hours that needs to be trashed is horible. Going back to Panasonic.

Vizio tv going dark


Back - light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis.

Some model sets; especially LED back-lighted types; the back-light inverter circuit will be part of the main power supply board [SMPS]. In such cases, the power supply board might need replacement.

I have a vizio p42 hdtv 10A, and it turn on, but with no picture. The sound is working fine, i can change channel and everything, exept, that it is totally black. What can i do?


Try leaving the TV unplugged for 30 minutes so the TV can reset itself.
If that doesn't work, most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
But, I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Plasma tv has no picture but green led is on


If you are not able to bring up the TV's onscreen menu while the picture is blank, then you have a problem with a video board.  If the menu does come up then usually the problem is with the device connected or its related input jack or cable that is in use. You may have to try another input or cable to be sure, but only if you are not able to see the menu.

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.
