Did this problem occur after a storm or power outage?
Does the TV show any signs of life at all (power light lit, blinking, click sounds coming from the set, etc.)?
There was no power outage to my knowlege
when plugged in the power light blinks. the blinking seems unaffected by turning on or off.
The blinking light indicates an internal failure of the TV.
There are several problems in your set that could cause this. It could be a faulty CRT , which would cost you more than a new TV to replace. other common issues are cold/failed solder joints and failing IC regulators, or capacitors. All of these problems are common with your set, and would require circuit testing and replacement in order for the TV to function normally again. Average cost for this type of repair will between $150-$300 depending on which circuit has the failure on the set. Given that a new LCD TV would cost you only around $300 for the same sized screen, it is not cost effective to repair this set. Unfortunately, there are no resets or series of buttons you can press that will solve this problem and the set will require component replacement to operate normally again.
