The view timer keeps cutting in some time i can watch tv for hours or five minutes does anybody know the answer


Go into Your Menu Settings and check your settings for the timer. Turn it to OFF. That should stop it from popping up. That's a friendly task some people do to limit how much TV They watch. Very normal believe it or not.

My tv is cutting off after about a minute on and


Look in your owners manual for how to reset the Lamp Hours and see how many hours you have on the lamp. Your doing good if you can get 3000hrs. These type of lamps when they get weak will quit and the buzzing you hear is the lamp supply starting it up again. so in short, I would say you may need a lamp. Today's sets ( DLP's) which you have, you cant judge by the age, with those it's by the hours. Hope this helps and let me know...

Is my picture tube going?


Most proj TV's of that type have 3 Picture tubes Red, Green and Blue. It's not likely that all 3 went bad at the same time in the same manner. So I believe you have a circuit problem, probably in the power supply stages, possibly a bad solder joint.

Hope that helps...

Most likely the issue in on the large signal board. The TV is going in to shutdown. Repair might run $200.00 or so.
