I found the above web site pretty helpful, too (AVForums), and have spent a couple of hours reading that thread.
Seems like the capacitators are often why the power won't come on. Also, some people mentioned that holding a blow dryer to your TV will make it come back on. According to the tech-savvy people that could mean that your "solder joins" are cracked. So when they're cold they'll contract and lost the connection,and when you heat them up, they expand and reconnect where they are supposed to. I'm not tech savvy and this doesn't explain much to me, but it's interesting, and I'm sure somebody will go "aaah, I see...."
I'll quote a post from AVForums:
"The main components that wear out are the capacitors which, with aminimum amount of electronics knowledge and a suitable soldering iron(you need one with a tiny point, preferably a butane gas powered one)and a powerful magnifying glass. This must be self supporting or onethat hangs from a neck cord.
The capacitors and any other parts you need can be purchased very, verycheaply from rswww.com and they offer a free delivery service or, foran extra fee, a next day service!
When you remove the back panel from the TV, you will see a few circuitboards and you need to locate the one for the power supply.
On mine it is really obvious as it is situated at the top just left ofmiddle. They all have numbers printed on the circuit board. Mine are2662 (25V 1000 uF) 2663 and 2664 (both 50V 100uF)
The ones originally fitted are '85 deg C' but it is best to replacethem with ones that are '105 deg C' because they will last longer.
These '85 deg C caps' normally have a guaranteed life of of 1000 hours,whereas the '105 deg C' ones have a guaranteed life of 2000 hours!
This being the case, when Philips build the sets they know that theywill probably break down after a minimum of 1000 hours of use. If wesuppose that the caps last for twice their minimum life span (2000hours) and the TV is switched on for an average of 5 hours per day overthe year one, ore more, of them will probably fail in the secondquarter of the second year.
With this knowledge, for high cost items such as this, you would alwaysbe wise to take out an extended warranty and Philips, or any othermanufacturer, should be obliged to include an information card warningconsumers of this fact!
The Aluminium Electrolytic - Radial capacitors in question are,usually, 2 x 100uF. The voltage, I believe, depends on the screen size.My 42" screen requires 50V whereas the 32" version uses 25V caps.
There is also a larger 1000uF capacitor, of a similar type, that willbe sighted close to the other two. This seems to be 25V, whatever thescreen size!
The only thing you must remember when replacing these caps is that thelonger leg on the capacitor is 'Positive' and the shorter one is'Negative' and you must ensure that you do not damage the circuit track!
If you are careful and have a steady hand it is quite an easy job butif you are not too sure, you will probably be able to find a localrepairer that is able do the job.
However, you have to beware of the Companies that offer a service wherethey come and collect the tv for a set fee, usually just under £100!They then work out the cost of the repairs and, if you give them the goahead, they deduct the amount paid from the overall repair cost.
I have looked into many of these and, even if you agree to the repairestimate, usually in the region of £300, they never seem willing toguarantee the repair for longer than three months, six months at thevery most!
When you consider that these components cost a matter of pence you can see the value of trying to repair it yourself."

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.
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.

Power supply board just die.It can be dead at anytime.Tries websites Shopjimmy.com,Ebay.com to buy a refurbish power supply board for the replacement.
