Question about Projection Televisions

1 Answer

KDP-65WS550 I have a question about this tv. The colors are way out of alignment. Someone from servicemanuals suggested I buy new IC's and put them in. I ordered them from them and put them in and its still screwed up. It changed the picture with the new ones, but its still messed up, maybe just in different direction. I am trying to find a place where I can buy a new convergence board for this (A-1405-077-A) but its not available anymore. Anybody have a clue where to get this part? Would a new convergence board come with the new IC's already on it? Thanks Dennis

You cant get new boards any longer, you can possibly get your rebuilt but its exspensive. I think all you can buy now are what they call "PCB Mounts" which are the circuit boards with no components on them.

Double images and colors are blurry .Blue,red and yellow wave coming up from the bottom of the screen on the lower left symptom is for busted convergence IC,you must replaced this IC in order that will works better again.STK 392-xxx ICs and it's associated resistor,this resistor automatically change value,can caused truoble even though you change the ICs.If you bring this to a service center they cost you $600 to $700,but if you buy the repair kit you can save more,don't wory it is very easy because there is intallation guide including in the repair kit.

Convergence on kdp-65ws550


youre looking at about 300.00 for that board if its still available as the entire D board need to be replaced if you go that route. Go to this link as they can get you a prive on a new board or they also sell just the parts and provide free instructions on how to replace the Ics and resistors in the convergence section. heres the link, leave them an email with your model number and what your looking for.

Sony KDP-65WS550


Nothing appears to be available from Sony on that issue. Sorry!
t sounds like you may be getting some kind of interference. What make and model of surge protector/line conditioner are you using?
Have you tried unplugging the set for say 20 seconds after the set has been turned off and the fans have stopped? It just may stop the problem.

When you say the you see lines throughout the screen, are they uniformly spaced vertical lines of random colors?
