Unfortunately that is a failure in the display electronics and is repairable only by replacing the display panel. I don't know what the warranty period is for this model, but check your purchase date and the warranty information. If the thing is just recently out of warranty maybe the manufacturer will work with you on a solution. Or you can contact them anyway and ask. Sometimes if you complain loud enough it works wonders.

I don't know if this actually will fix your problem, but all LCM 22w2's are plagued with the 'white screen of death' and eventual power shutoff, including garbage characters and faulty menu, video output, etc. Here's how I fixed it.
The Westinghouse LCM 22w2 has bad capacitors on the yellow power supplyboard. This is a common problem plaguing motherboards and LCDflatpanels that use capacitors from Taiwan. If you know how to solder,or know somebody that can, it's actually a pretty easy fix. Take outthe yellow circuit board on the inside, write down the specificationsfor each of the capacitors (the cylindrical things) go to theelectronics supply store and get the replacement capacitors. You can goover the voltage specification (not under), but keep the capacitancevalue matching. Replace one at a time. Go to www.badcaps.net foradvice, tutorials and training on doing this. *You really shouldreplace all the capacitors*, but the very large one next to the powerplug I did leave on the board because I couldn't find a match. To mydelight, 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.

I fixed it! It's the power supply board.
Your problem isn't precisely the same one I had, but I have the feeling you're not saying that this was a problem that gradually got worse over time and now it won't power up.
