I have a Hitachi Model 50ES1K projection tv. The picture would bounce up and down and eventully would stop but would randomly start again. Now I try to turn the tv on and i hear a click but no picture or sound comes on and the red light is not on. Is this a lost cause or can it be fixed.

Your problem is a converge alingment. in most JVC projection TV,s The main problem for to happen is heat eventully breaking down the solder on the converge ICs which destroys them you can still bye them at most electronic parts supply stores .
ck for dry solder joints if you take rear cover off and just lightly tap on convergence ic heat sink if the tv jumps then you have to remove the board and resolder the joints. also if you have a magnifying glass ck all solder joints on board when it is out
I have seen this symptom a lot recently. There is a 9 volt regulator on the small signal board, and the output voltage on this IC has dropped down to about 8 volts, which causes that symptom. Replacing that regulator should cure your problem, and when I make a housecall for a set like that I charge $150, although I hear that the average service center charges a lot more than that. I also believe that it is never a good idea to leave a projection TV on all the time, so whoever told you that has no idea what they are talking about.
