I had the same problem. i was told by one of these so-called experts @ fixya that my flyback transformer needed to be replaced (the 8 blinks on the standby was the indicator). but i recently replaced it and im having the same problem. sorry. no advice. good luck.

My KP-51HW40 clicks off after running for a period. The red power light blinks when it goes off but screen stays dark. When TV is shut off for a while it restarts and runs fine. The "On"...


Hi,
KP-51HW40 shuts off due to incorrect white balance and blue arch lines is an evidence of that incorrect white balance. I hope tv standby red light would flashing 5 times then 3 seconds pause and again 5 times when tv shuts down.
This is rear projection tv that has three picture tubes (red-green-blue) inside to generate picture that projected at front screen. These three picture tubes must be drive with correct drive voltage to produce good picture of each color.
Solution for your tv problem is Screen Voltage adjustment that can be done easily if you are handy with electronics stuff repair.
Let me know your expertise level to guide you more and if you feel unconformable by tv repair then local tv repairman will help you to adjust white balance in tv.
Hope these info will help you.
Let me know if you have additional questions.
Thanks.

5 flashing light code,unplug CR board,now 8 flashing light code


If you put the "CR" board back on, the error code will once again be 5 blinks. Your problem is likely the TV's IK blanking circuit. The Kine driver ICs on the CRT sockets boards CR, CB, and CG need replacement along with a few components in the 200 volt supply to the circuit.

Green flashes then tv turns off


or a new lamp. you could first replace the lamp.
the screen might work fine for a couple of seconds, but then it fades away or deteriorates. This means the lamp is going bad.

Sony turns on and off again


My tv too had a blue screen problem. Then it started to shut down after staying on for less than a minute. I thought that I would with a huge repair bill but I followed the directions at this link: http://www.somelifeblog.com/2007/06/sony-projection-tv-red-line-repair.html and now my tv works perfectly.

Sony KP-51HW40


I had the same problem with mine 2 years ago (TV was 1.5 years old at that time) I had extended warranty on TV and it was fixed by Sony at no cost to me. Now yesterday I have another problem with it. All of a sudden screen went BLUE. No Sound either. It could be the CRT (That's what I read here) Out of luck this time. Will call local Repair shop (70 miles away) and see how much it will cost to fix it. Good luck.

I read it online that this is a very simple problem. It needs highvoltage splitter. I tried to open the front panel to see where the splitter is. However, I need some hint as to how to open the front panel. Good luck. Kiran
