Question about Westinghouse TX-47F430S 47 in. LCD TV
Westinghouse "46 LD4680 will not power up...was working fine yesterday but today will not work. In the past 10 months it has acted suspiciously when powering up, but once or twice, it came unplugged by tilting the tv back and forth because its mounted on the wall. since I discovered this, I secured the ps using 2 zip ties plus secured the cables as well.
It sounds like the power supply is having an issue. Yes its easially replaced no special tools required just a screwdriver. You can get the power supply board from www.tvcircuitboards.com

Hello I have a Westinghouse TV model number TX-42F430S Sometimes it comes on and sometimes it does not. It has an orange light in the center below the W emblem in the center of the TV. when the TV actually comes on that same light is blue Is this the reason that the TV will and will not come on sometimes? is it a power issue mayb a power circut issue???

This kind of failure is very common; that is why I suggest that one should keep the old CRT TV, buy a converter and put them both in the garage or basement so they are handy when our s*e*x*y new sets go belly up.
With fair confidence I can say that the main power supply has failed.
If you want to try this on your own, it only will require the removal of a few screws and a flashlight.
- Unplug the set overnight. - Remove the rear housing - Use some logic and these tips; look for a separate board with larger than average parts on it and seems closer to the power cord than others. This will be the power supply.
Check the board over for something that looks like a part number and record it. If you find more than one, one of them will be the bare board number, the second (sometimes on a sticker instead of printed directly on the board) should be the part number for the assembly.
Search for the Westinghouse service company nearest you and call them with this info. Ask if they repair these or just sell new ones. If it is the latter, don't pitch the old one, continue to look for a repair service that will take it on after you have the new one in place and can watch your favorites again. The new supply will likely cost between $90 - $150 and with a little common sense, most anyone can remove and replace these in the set. Expect any repair to cost about the same as a new supply; US technical labor costs more than Chinese assembly labor.
These supplies can be as reliable as the primitive older type but companies refuse to use the high-grade components necessary to give them a long life so they fail much sooner than the old, less efficient kind known as 'linear' supplies.

I just fixed a neighbor's by replacing the 2200MFD capacitor on the power supply board. Thanks for the help, worked great. If you replace it got for a 16V instead of the 10V and hopefully it won't fail that way again.
Just be careful and take notes when you're digging into it. And mark exactly where the card cage is before taking it loose.
