SAMSUNG DLP REAR PROJECTION 52'' SHUTS OFF AND POWERS ON.

TV will power on with a whistling pitch that gets higher pitched for 1 second. Then turns right off with no picture ever displayed. It will repeat this cycle every 20 seconds or so for ever unless power button is pressed. Thanks for any insight. TV is 2.5 years old. HDTV monitor 52".

My tv makes 3 even high pitched squeals when i turn it on. about 1 second each, then powers off. No picture no sound. All imputs. What do you have for suggestions on what it could be.


One of most two common reason why your set will not come on, is because it has lost the high voltage, the first thing to check is your horizontal output transistor, to see if it is shorted, it will be located bay the flyback, mounted on a metal heat sink. That is what is causing a squealing noise.
