Question about Sony KP-57HW40 57" Rear Projection Television
I go turn the tv on, about 10-15 minutes of being on, the picture starts getting red. It use to take a while to get fully red but now it turns red immediately. Can you tell whats the problem and if so is their any live instructions i can watch and follow.
Locate the master screen / Focus block with 6 adjustments and turn the red Screen down a little.

Are you sure you didn't turn the knob too far down? Just a though. I don't know off hand which one is the D board but the boards are marked. Please be careful when working on TV sets as they produce high voltage which may reside even while the sets is unplugged. Also I would do more research on this problem before purchasing a new D board. I have been told that the picture tubes in these sets go bad. G what a bummer guess what set I own :( Here is the code for 8 blinks, it looks like you may just have to replace a part on the D board.
8 times, Diagnosis: High voltage error. Possible cause: T8005 is faulty. (D board)
I hope this helps, keep in mind its hard to diagnose issues without actually being there.

There are three fans the one that usually fails is located on top of the optical block and cannot be reached by the owner unless you take the set apart yourself. What is happening is that one of the fans are not spinning fast enough or has stopped altogether. The best solution is to replace all three fans cleaning may not be enough to get a slow fan up to speed, and the tech should blow out the dust in the duct work. This is what the tech coming out will (or should) be doing. Also some fans will have an intermittent startup, and cause this intermittently, so it is a good idea just to replace the fans instead of just cleaning them.

I had the same problem in blue. I took the right front speaker cover off (pops off) and the access panel on the right side 2 - 4 screws. In the upper right corner is a black plastic box with 2 rows of 3 adjustment screws. All I did was turn one of the "screen" screws (not the "focus" screws). Hope this helps. May only be a temporary fix, but good luck...
