I have the same problem too. I have known that panels with this problem (6 blinks at startup) are replaced in US for free. Unfortunally I'm in Russia and nobody but myself can help. Please let me know if you have a solution for this.
Thanks.

I have one and have been told the main board is not working.
Cant get parts. Do you want to sell your main board.

Very possible,but yet,this might be the manufacturer defect power supply which they will fix it for you free;but before we jump to this conclusion,you need to test it first:
-Unplug the power cords.
-Unplug the media video cable from the box to the tv.
-Check all the pins on the video cable are in place as well as the connectors both behind the TV and the media box.
-Reconnect the media box and TV with the video cable(DVI+VGA in one) and have at least a video component hook up to it(ex. dvd player/VCR or comcast box) be sure this video player is turn on and running,at the same time,be sure it is under the right video input.
If you have tried the above steps but still doesn't work,call 1-800-pioneer Tuesday-Thursday at7amPST and address your issue to them.
Let me know if you have any additional questions!

It sounds that the main digital board to your TV has damaged. But, before make it confirm, a through check should be done. Contact any experienced service technician for help. The work is skilled one, that a user cannot do it with ease.
