Question about Projection Televisions
We usually refer to this event as the "kiss of death" syndrome. It occurs because the protection circuit (a sort of electronic fuse) has sensed that one of the many sections inside your tv has exceeded the normal current flow. This is generally because of a shorted condition somewhere in the circuitry.
The protection circuit shuts the set off and keeps it off until the fault is corrected. You can sometimes get it restarted by doing a reset. Do the reset by unplugging the power cord for 4 hours; then power it back up.
The problem is, if you cannot get it restarted, that you don't know where the shorted conditions are. It could be in any of the nearly 10 sections within the tv. It requires an expert tech who knows how to get inside, defeat the protection circuit and test the various sections.
Most common is a problem in the high voltage/horizontal section or the vertical deflection amplifier section. These repairs are quite expensive and will run as much as $200 to $300 - sometimes more.
So, I cannot give you an exact repair estimate because it is impossible for me to predict where the problem may lie, but most of the time it is on the expensive side of the range.
Sorry for the bad news.
