Yes your problem is the high voltage power supply , on this problem you would has to hire a tech to fix this problem , the problem is a voltage control ic who turn on the high voltage if this is not working properly the tv never come on or sometimes take forever , normal repair cost is about 200-250

I think this sounds like my problem (need to replace the projector lamp). However, when I hit the "on" button, my SXRD 50" blinks green for about a minute then starts blinking red. Can you confirm the bulb solution? I was very pleased with this sight when my fan malfunctioned. I got the fan in a matter of day's from Sony and it fixed that problem.

I found this solution from SONY's website.
The STANDBY light will flash if an issue is detected within the television. This can sometimes be resolved by simply following the steps below to reset the television.
If the issue is still unresolved after following all of the troubleshooting steps, service may be required. Please note the number of times the STANDBY light flashes and relay that information to the service center.
I hope this helps.

That is a diode in the sub power supply, it is a small board with only a few parts on it to the left of the d board, for the zero crossing detector. D6301 sony part number 6-500-567-21

Can you unplug the TV for about 15 seconds, and then plug back in and watch the stand-by light. Tell me how many time the stand-by light blinks in regular intervals. If it doesn't blink at all, you need to change a fuse on the g-board. Once this is done run back through the stand-by blink light process, and more troubleshooting can be done if problem isn't already solved. If the stand-by light just keeps blinking with a count over ten just tell me, and I'll look for other possibilities.
