Question about Sony Grand WEGA KDP-65WS550 65" Rear Projection HDTV

1 Answer

KDP-51WS550 with 10 red led blinks upon power-up

Does anybody know what to replace to fix this TV? The serice manuals say Q8013,Q8014,R8051, and IC8005. I replaced them already and still the same issue. Can someone tell me what is causing the 10 blinks? I would really appreciate it. The TV works from time to time but mostly doesn't. I would really appreciate it. I have a lot of experience in soldering and repair so I can do just about anything. Please advise.

My sony TV, when I press the power button it sounds like it is going to turn on then the standby button blinks 10 times then stops for 30 secs and then blinks another 10 times. What is wrong?


Flashing of the standby LED light 10 times (KP-46WT520) is a "High Voltage Protection".
Affected parts are as follows :
• Q8014 or Q8013 have shorted replace along with R8051 on D Board.
• IC8005 is damaged (D Board).

You must know how to test transistors, resistors using the multimeter if you are going to DIY.
If you don't have necessary tools and test instrument and can't troubleshoot the unit yourself, I would advice you to seek for an assistance of a qualified TV Technician to isolate the above faulty parts.

Hope I helped you.
Have a nice day!
Thanks for using Fixya.

When i press the power button the stand-by light blinks orange about 10 times and goes red again. and the tv never comes on

The blinking light describes the nature of the problem to the service technician. The error message varies from manufacturer to manufacturer and model to model, so more information is necessary to provide an accurate solution.

If this is a Sony Projection Television, (for ex the KP51WS620,) 10 blinks, pause, 10 blinks, etc. means "Hgih Voltage Protection" and the probable cause locations listed are as follows:

1. Q8014 or Q8013 have shorted replace along with R8051 on D board.
2. IC8005 is damaged (D board).
3. G2 is improperly adjusted.

These are starting points for a qualified service technician. I hope that helps.

Thanks for using FixYa. Ten blinks on Sony HDTV means-- Check Transistors Q8014 and Q8013 on D- Board for shorts, leakage, or bad solder connections. If the transistors are bad, then also check R8051 and IC8005, these are also on the "D" board.

Please do rate the solution and revert for further assistance.

Thanks Rylee
