Question about Westinghouse SK-26H520S 26 in. LCD HDTV
The television plays normally, but suddenly the screen goes black. Other times, the screen turns to hundreds of vertical stripes of all colors. When it goes black or striped, the remote works but it has a 5-second or longer delay. The problem is temporarily fixed by turning off the power and restarting, but the problem persists. I notice no patterns with the problem. It seems quite random.

I fixed it! It's the power supply board.
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 problem 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.
