Question about Westinghouse LCM-22w2 Television
I fixed it!
The Westinghouse LCM 22w2 has bad capacitors on the yellow power supply board. This is a common problem plaguing motherboards and LCD flatpanels that use capacitors from Taiwan. If you know how to solder, or know somebody that can, it's actually a pretty easy fix. Take out the yellow circuit board on the inside, write down the specifications for each of the capacitors (the cylindrical things) go to the electronics supply store and get the replacement capacitors. You can go over the voltage specification (not under), but keep the capacitance value matching. Replace one at a time. Go to www.badcaps.net for advice, tutorials and training on doing this. *You really should replace all the capacitors*, but the very large one next to the power plug I did leave on the board because I couldn't find a match. To my delight, the white screen of death went away and it was working as new!
I saved a ton of money fixing this, it's definitely worth learning how to solder to do this.

This is not a solution but I've had the Westinghouse LCM-22w2 for probably a little over a year. A few months ago it display all white when I turned it on. Along with this problem the on screen display of the channel select and the UI config menus were corrupted. (although you can still change channels and use the menu functions)
The white out problem was a nuisance for a couple months and I learned a few things about it. First of all, it seemed to only happen if I turned the monitor off and let it cool down. Changing the channel modes doesn't help as much as just turning it off and on until you get the picture back but it felt like maybe it was trying to warm up or something
a couple weeks ago, the white screen problem turned into: everytime a resolution change happened, the screen would flicker and blink corrupt pixels. The only way to get it to cooperate was to turn it off and back on again. It's not really such a pain, when windows boot it changes resolutions like 3 or 4 times but in the end, I'm thinking 'ok, not a show stopper'
Today my Westinghouse was in the stages of restarting windows when it went blank....at first I thought it was just a resolution recycle like I was mentioning above. But no, now it has no picture...on any channel....now the little orange LED on the front to indicate power does not light up.....there's no high frequency noise to indicate it has the will to live....I can unplug it and plug it in and it squeals for about 3 seconds and then nothing....a couple of times the squeal has remained on (still no LED indicator on the front) but nothing happened still...it just seems like it might for a second but no.....
So I guess my point is....if you see the white screen treat it like a strange and unsettling death omen.....the resolution handicap was next, and then ....nothing.....nothing....it was just gone....like it had never had a soul in the first place....Goodbye my friend....goodbye 22w2....we barely even had time to know you...but I guess one gets what one pays for and westinghouse's purpose in life is to serve as a warning of that lesson :)
