    Brand new out of box. Bought it from walmart's sale starting 3AUG. Plugged everything in and absolutely nothing happens when I try to turn it on; not even the monitor config menu works. No flickers, whites, noises, LEDs... nothing.

I fixed it! It's the power supply board. You might have the "white screen of death" problem, and if not you may just need a new board. The board is yellow, it has markings on it that you can look up on a search engine for resellers, and I saw several going for $20-35 after searching google.

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.

Thanks MattKC for the solution! I just fixed mine too. I was able to find some links to some replacement power boards across the 'net, for about $45 including shipping...

But then I got bold (and since the monitor was given to me b/c it didn't work) and decided to try the fix myself. Went to Mouser Electronics (www.mouser.com) and spent $10.50 including shipping (I don't know of any good local component suppliers around me, and RadioShack just doesn't have jack anymore), and just replaced them myself. There was one that I didn't replace (22uF, 50V cap) because it was real close to a lot of surface mount components, and my soldering skills are not all that great, so I didn't want to chance it... Replaced all the rest though, and ta da, now it powers up just fine!

This solution worked for me. Thanks!

TV won't turn on power light flashes 10 times


Switch off the TV from remote, then switch off the on/off button on the TV, remove the plug pin from the power outlet. Cool off for 48 hours and then retry. If nothing works, better refer it to a qualified service technician.

My panasonic TH42PX60U won't power up. No red light flashing. Completely dead. I tried unpluging and using different power outlets. Still nothing. Any help?


1. Check all cable and input connections are secure & all are tightly connected.
2.Check power cords and also power outlet , if possible try to unplug and reconnect . A replacement of power cable or use another power outlet is another good option.
3. If you are sure that power is reaching your TV(check it out with a test lamp that both neutral & ground or earthing is functioning, i.e. the test lamp glows) then probably the power board needs replacement.
