It will not be easy fix since you will have to do in-depth troubleshooting to find out which board/s are bad first. So please read my guide and you will have some ideas what to look for, voltage checkinga and visual inspection in the power supply will be the first place to look.

Westinghouse 22 lcd monitor. faint click and went


More likely the filter caps failed and may have taken out the inverter fuse and the MOSFET in the inverter circuits also. yoo need to open it up and inspect the inside, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums

TV Turns on picture comes on for 30 seconds then picture goes off and sound stays on. Even after leaving tv on the sound stays but the picture does not come back on. Its a westinghouse SK-32H540S


This is not the fix for this TV. I guarantee that none of the capacitors exhibit the common bulging characteristics of a faulty capacitor. The common answers to everyone's questions are to replace the capacitors. Most likely the culprit is the inverter board.

My westinghouse tv works for like 10 minutes then shuts off


The first thing I would recommend for this problem is to do a factory reset. The way to do this is to go in to the menu, go under the settings tab, and select factory reset (in some models it will only say reset). If this does not fix the problem than you will need to replace your power board, you can find the parts you are looking for by emailing Westinghouse part department at parts@wde.com, they will let you know price and availability on the power board. If this solves you problem please rate my help on this website.

I bought a Westinghouse 26" Widescreen LCD tv less than a year ago and we are having troubles with the HDMI 1 channel. My son has his XBox 360 hooked up through this channel and it will randomly go blank...


I would recommend to call the Westinghouse customer service since you are at least close to the year warranty, their number is 1800-701-0680, other than that the only thing you can do is to do a factory reset by going in to the menu, go under the settings tab, and it will be the last option.

Westinghouse 32" TV randomly shuts off


It is a good possibility that you have 1 of your inverter transformers going bad. I wouldn't wait to have it looked at. It can cause more damage if the bad one let's go all together.
