I have a Sony KP-51HW40, 6 years old. It had the turned itself the blue screen and off problem before, I followed the instructions that I saw in the web to adject the blue CRT in the front panel. it is a litter better, so we can watch the TV for a 30 minutes, alter that, it TV is lossing its blue, and picture is greenish. That depends my luck, I may watch for another hour before it turn it off. Again, it has 8 blinks on the panel.I heard it that I must replace the D Board. What is the instruction to replacing the D Board. What is the part number and is that the cause for this TV?
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.
