The projection bulb came on,but didn't stay on mean the bulb have problems,dosen't mean projection bulb it still good.First must replace a new projection bulb to make sure for the elimation for the projection bulb is the problems.These DLP tvs require new projection bulb every 1 1/2 or 2 years by watching the tv like 4 or 5 hours daily.So there no lost there for trying a new projection bulb alway can save it for later use.The secound could be the board that call the Ballast board have problems too.The Ballast board only job it is to ignite to the projection bulb and make it work.Replace the Ballast board too,if the tv new projection bulb react the same way.
Your signal board is in need of repair. This is the board with all the rca jacks and antenna connections. The high pitch hissing sound was the best clue ever.You will need to see a tv tech and have him rework or replace the convergence board [aka the signal board] Good Luck and thanks for asking!
Sounds like you are tripping your crowbar circuit. This is most commonly caused by one of the Red Green or Blue brightness adjustments, adjusted too high. The crowbar circuit protects your high voltage guns from getting damaged. I know this because I just did this myself. My adjustments were behind the lower rear panel in a small box screwed to the chassis. There are 6 tuning pots on mine. 3 for focus of the RGB and 3 for brightness of the RGB. The focus ones didn't seem to have any effect on the crowbar circuit. However, by turning the brightness down on each of the RGB pots I could get the T.V. to stay on indefinately.
It might be the the socket board on this model not the crt tube. Closely look at each tube these tubes end up contaminated. They start looking like lemonade inside. Usually the blue and green, with the tv off see if the green and blue are as clear as the red with a flashlight. You might want to call a service center. Cheaper in the long run over the cost of a tube.
My tv was doing some of the same type things I touch one of the manual buttons ont tv and the channel would change or the volume would go up or down. I changed the control board behind the manual buttons on the face of the tv and now it works fine with or without the remote.
the part no. is 313501707611 go to sears web site type in this number and order it. this part will come up as 60P8342 but thats ok becouse the 50P8342 and the 60P8342 use the same part number I know I have both models and changed them both using the same part and part number.
