First color alignment problems then no pix or sound, just chirpin
We had our rear projection phillips tv (60pp920217f) fixed about a year ago. The second repairman said the first repair man didn’t put enough grease to insulate it so it overheated. The second guy couldn’t get the red in the left corner to go away so it looked like a little rainbow in the corner after he was done. He said he worked on the lsb board, convergence chips and resistors. The very next day it wouldn’t turn on. No picture or sound, just chirping. We called him but he refused to come back and check on it and said he was out of business. We would like to know if what he worked on could have caused our problem now or if he could of made a mistake and shorted something out? We live in a small town and it is very hard to find someone to work on these TV’s. We’d appreciate any help you could give us.

Re: first color alignment problems then no pix or sound,...
If the unit is chirping your convergence amps are out again,or you have a shorted Horzontal output transistor. Not likley for horz output to go out after convergence repair. If he did not replace the 6.8 ohm resistors along with the convergence amps the convergence amps would overheat and short out again.This would explain why the corner would not adjust out. Not a very good buisness practice on his part.Here today gone tomorrow?

Tv have a problems known as a convergence problems,it is dead.The tv convergence board it is dead,that why ur tv picture are R,G,B colors lines mis alignments,have colors shadows picture or 3D picture lood alike?The tv convergence board require changes 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence picture problems.The shop will cost u like $300-350 for parts and labors.

replace the lamps and then run the synch routine from the main menu. unfortunitly with the expense of the lamps and the low price to replace projection tvs it might not be worthwhile to fix but just replace.
HINT wait till after new years, LCD large screen tv sold about 35% of what was expected during xmas so they will be real real cheap after the 1st of the year
Are the colors out of alignment and unable to converge back? If so its the convergence ICs need replacing. If the convergence isnt out of alignment you have whats called a pincushion problem. If you would like a link to where you can obtain the service manual for this model let me know.
It sounds like the 3 "GUNS" are not aligned.
One the controls at the bottom, left hand side You will see an arrow pointing to the first 2 on the left.
That will allow you to scroll down the list of options until you see....CONVERGANCE!
make the red gun center by using the up/down arrows on right. Then add the next 2 until you see a white X or cross.
