Question about Sony KP-65WS500 65" Rear Projection Television
If convergence ICs are changed and pico fuses are changed, if the colors are still bad, check the resistors connected to STKs. Make sure you check there values with a good DMM. But if all there are good, power regulators ICs are good. The stdby power supply is controlled through D board and if the set is not comming on and the light is blinking its most likely the d board. all caps need to be checked with a good ESR meter. Hopefully you are able to resolve the issue. More specific diagnostics can be done using the service manual flow charts. If you dont have one download it from tech support on fixya site.

No I have not resolved the issue yet. I had them test my D-Board again and they say it is fine. I was going to check the fuses next but you say that wasn't the problem with yours. I'm not sure what to do now..
