I have a Sony KV-34HS510 and when I connected my ReplayTV to the component input the image I got was only half the screen and the other half was either white or black and white horizontal lines. The repairman from Sears fist thought it was a problem with one of the boards but it turned out to be an issue with the factory preset fro the virtical and horizontal lines. So he zoomed the image in with the service settings, but he went to far and on the component inputs I am loosing the edges of the image past the screen edges. I was hoping that someone has the service manual for this set.
You can get the service manual HERE If you do not know what you are doing, you really should not be playing around with the service maenu. If you do want to play with this menu, make sure you you write down the numbers of every adjustment before you change anything. This way if you do make something bad, you can simply put back the correct numbers of where you started. Just do not go overboard with the alighnments as I have seen a simple repair turn into a costly one. Good Luck
Larry Thank you for the link. I had a repair service appointment for this morning but they lost the record of it. So its another week until I can get a service man out. I'm still considering getting the manuel and I will keep your warning in mind if I work on the problem myself.
