Sony TV Model KV-32LS36U Dead 11 flashes.

[pan]

Hi 
I have picked up a Sony TV Model KV-32LS36U for repair.
Its Dead leds flashing 11 times I have checked Q606, Q607 & R603 (0R1) these components seem to read ok.
Also checked C641 no prob found, checked the L/O Trans that’s ok too.
Found a couple of caps that had high ESR reading C638 & C639 changed them but the fault still the same. 
Just hoping someone can shed some light and might please help.
Thanks
Pan
