Advice please for the non-techy.

I have a Toshiba widescreen HDTV bought in 2004.

When you turn it on now you have full audio but a very wavvy/staticy/blurry picture that flickers and you are still able to see some color. If you leave the TV on for a while, this behavior eventually subsides after about 20 minutes. It seems to happen only when the TV is cold or hasnt been on for a bit.

Any suggestions? Does this sound typical? How can I keep from being taken to the cleaners by the service desk at the store we purchased from?

Thanks

Almost certainly there is an internal fault/s- all you can do is check power ok, antenna ok, then find honest repairer.

Correct. But this can get tricky. If the picture is still messed up you may need to load the default data back to the eprom.

What would be my best option? taking it to the best buy where I bought it or searching for a TV repair shop? What kinds of things do I look for, what do I ask, how do I prevent from getting scammed like at the car repair shop, etcetc? advice please. Thanks for the input already.

Cheers

Tell them you need the hyper board repaired or replaced. List the board is about $195 with labor expect about $350.

All these craps comes from China just because it say SEARS it doesn't mean they made it. to repair it forget it $350 i buy a new one. what you can do is go to radio shack and by one can of freezer that you can safely spray around to find the bad component and replace. be carefull some of the stuff inside can kill. even a spray to blow dust off keyboard will work in your case.
