Question about Sony KP-51HW40 51" Rear Projection Television

1 Answer

Sony projection tv with dual tuners; only one tuner appears to be working now.

I have a Sony 51" projection tv model KP-51HW40. It has dual tuners for picture in picture (PIP). I have had the tv hooked up to a dish network dual tuner HD receiver and my HD picture had been great. I was able to watch HD programming through the first video option, and regular programming on the 2nd picture. Now I am only getting video from the second picture, and it is no longer in HD.

My guess is that the first tuner on the tv is no longer working, so I'm only receiving the standard definition signals through the second tuner. Any ideas how to fix this?

To verify that the tuner is the problem, move the cable from the second to the first. If you don't get a signal, the tuner is bad. The main tuner is part number 859843000 and is available for $47.38 from tritronicsinc.com

    I tried that with my KDF60WF655 and it still won't work. I changed the complete A bord out of a working one with a cracked screen and it still won't tune in any channels. Not even if I hook up a VCR on channel 3, nothing. What could be the issue? I have a KDF55WF644, could I change out the whole chassis and put it in the KDF60WF655?

Screen shakes / jumps vertically on my Sony KP-51HW40


The jitter is called a vertical sync problem. The problem is on the "A" board. It can be replaced or rebuilt but will be quite expensive to service.

Below is exploded view of your Sony KP-51HW40 TV rear side which shows board names and location.
You need to check D Board for convergence ICs and these are marked as IC8001 & IC8002 on circuit board.
