Sony KDP-65WS550 flashes when you try to turn it on

I've been reading about the flashing light when I try to turn turn on my Sony KDP-65WS550. I noticed that when i hit the power button on the front to turn it on, the light will flash red once for the attempt and THEN flash the number of blinks for the code. I'm getting 10 total flashes when I first hit the button and then after a slight pause then it will flash 9 times. It will continue to repeat the pause and 9 flashes as long as I let it. I have been able to get my TV to finally come on if I hit the power button enough. I think my TV may just be dirty, I'm going to try and blow it out with a can of compressed air. Update...didn't do anything. Maost things I've read says a Sony should only flash a max of 8 times. Any ideas?

    I had the same issue with the 9 flashes. I located D6114 and started to remove the board. Once i got the board out I checked the diode with my multimeter on the diode check position. On a good diode you should see .7 volts (silicon diode) one polarity and OL with the lead polarity switched. I was only getting .55 volts and OL. I went to Radio Shack and got 2 of the 200V 1A diodes for 99 cents. Replaced bad one with new one and put the TV back together again. All works great. I reset my faults back to zero and turned TV on and off about 6 times. I then rechecked faults and had zero. I hope this helps. I have a Sony KDP-65WS550. I used this posting and a few others I found to correct my problem...Thank you all for the help. For future reference the D6166 is a misprint. It should say D6116. You TV should only have one of them, so it's just a matter of which one your model has. Thanks again fixya.

    My Sony KDP-65WS550 also does not turn on. It flashes 9 times. I have read and understand that replacing diode D6116 & D6301 on the G-board fixes the problem. The tv cover is off and I am having a hard time locating the G-board and the diode, I do have the expertise to change the parts in quiestion. Can anybody point me in the right direction on where I can locate these little suckers...thanks in advance!!

When I turn my Sony TV on I get 10 flashing lights, the sound comes on for a few seconds ad then goes silent. I get no video at all. I power it up again (with the 10 flashes running) and the audio comes up again and goes silent again, it then starts to flash 5 times over & over again on my sony kdp-65ws550

No the DLP units can flash more than 8 times. 9 blinks mean Zero Crossing detector which means diode number D6166 or D6114 is open they are on the A board.Let me know if you need any further info.

I have a KDP-65WS550 when i turn the power on it shuts off by itself, I've tried all the reccomended fixes and none have worked, the red light is blinking 10 times

Hello Mike
I don't know what else have you done with your TV. Yet, from the number of blinking code, I do understand that its video out board has the trouble. But, before going forward with you I want to know whether you are aware in electronics and have some experience in serivce TVs, and can follow the schematic diagrams, if I send it to you. If you aren't aware in electronics and cannot follow the circuit diagram of this set, there is no use of going forward. If you are confident, inform me. I'm ready to assist you. OK.
