Question about Flat Panel Televisions
I purchased this TV from Best Buy a few yrs ago. What happens is a random act. When either just turning on the tv or changing channels, the color will go from being perfect to a green tone. Is this the tube going out or what could it be? The model # is IS TVO 40922. I really like the picture on this tv, but not when it turns a green tone. What do I need to do?
check for capacitors on the power supply that are puffed up. Also the mai board can cause this but the power supply is where i would start.

Most likely the TV has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you the flashing red light codes, circuit diagrams, test points, and part# lists. Usually, cost under $20.
I hope I shed some light on the subject for you.

There are two places to look for the problems, the backlight inverter board and the power supply. Look at the power supply first since it is easier to get to, look for burnt parts, bad capacitors, etc.
Please post back what you find.
