Wierd pwer problem

SOURCE: No Signal

You will have changed the video/audio input, on your tv, it should be an input button on remote. The signal will either be on AV1, AV2, AV3 Component or HDMI.

SOURCE: Tv doesnot power on

two options _bad backlight inverter or the main board ;eed to be change.

SOURCE: when I push the power button, the blue light comes on but tv doesn't

It is the capacitor. It is really easy to fix, and it will cost you about $4. The capacitor is on the power board and it looks like a small battery. The bad capacitor will have a small bulge on the top, the good ones will be flat on top. You can buy them at Radio Shack. Just look on the side of the capacitor to see which one you will need. If you need any further info I would by glad to help. I have a 40in polaroid that this happened to and it works like a dream now.

The most likely the TV has a power supply related problem.
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 circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.
