Pressing channel buttons will turn light blue for longer and a quick flash on the screen then back to red light no picture shows on screen. tried power resets from other forums no luck. I am wondering what else to try for this model or what could be the failing part to replace.
I had the same problem on my Westinghouse 32 inch TV. The internal main power supply went bad and had to be replaced. I had a TV repair shop do it. It was about 8 years ago. Haven't had a problem since. I think it cost about $70 for parts and labor. Nowadays TVs are pretty much a throw away item if they go bad. TV repair shops are getting hard to find plus the cost of TVs has come down so much sometimes you can get a new set for what the repair would cost!
Testimonial: "i have much experience in electronics just never worked on this model tv. the power board would cause the indicator to not work at all if it was failing i suspect it is the main board since there is power getting to everything and at proper volts and amps."

Hello, reset in this case is not a solution. Maybe your lens is stuck. For further info please contact me at LIVE session. Best regards, Arpi

Bad Convergence circuit , replace 2 STK392-110 & fuse will take care the problem

The power supply is in the protect mode. There are many things in the set that can cuase this. Most likely there is a short on one of the circuit boards, or the power supply itself has failed.
You will have to have the set serviced in order to get it going again.

I just checked and my tv was purchased with a credit card that gave a double warranty. I have to fill out some things but it should be fixed eventually...

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.
