I turn on the tv , sound but no picture and after a few seconds it turns off and flashlight blinks on front panel 10 times and after a pause repeats blinking

Had the exact same problem on a KDP-65WS550.
I replaced IC8002 (MCZ3001DA) and IC8005 (TL1431CZ) on the "D" board and this resolved the problem. Total cost including parts and shipping was around $35.00.

My tv turn red and blink 13 time

Hi ,
I had same problem my TV. Replaced IC8002 on the 'D' board.
This is what we did:
1.Bought 2 x MCZ3001D from WES components in Ashfield Sydney Australia for $11.20 (each).
2.Friend had an 18 pin machine spun socket (not the crappy ones on EBAY).
3.Took back off TV
4.Put the 'D' board in service position
5.Noted which way IC8002 chip sat (Where position 1 is), also noted which 2 legs are not soldered.
6.Cut the black plastic that was covering this chip underneath (where D board screws into) as this is easier than removing the 'D' board.
7.De-soldered the IC8002 chip with a proper de-soldering iron. These are expensive though.
8.Soldered in the 18 pin socket.
9. Set the chip into the socket.
10.Tested TV, worked fine.
11. Put it all back together, plugged in Tivo, DVD etc etc etc and all bloody good stuff.
12. I now also have a spare MCZ3001D which is taped to the back of the TV for future replacement, which is now easier since its now in a socket.
