Question about Flat Panel Televisions
Plasma TV won't turn on. The light goes from red (off) to green, you can hear the 'click' but after a few seconds, you hear the click again, the green light goes off, and the red light flashes three times, pauses, flashes three times, and this continues.
If you use the on/off switch on the side of the TV, the light turns green and stays green, the fan comes on, but the TV never 'clicks' as it does when the display starts up. Pressing the side button again shuts off the fan and the light goes red.
this requires a replacement of the power supply board. This is per Pioneer tech support whom resolved my issue when I called. Hope this helps!

when a television turns off by itself and flashes as you say, it indicates that there is a problem inside the tv. If you keep trying to turn it on you may do more damage. It could be something as simple as a faulty fuse inside. If you have no expierience with electrics I suggest you get it checked out by a professional. I had a similar problem with another tele model and it was the fuse in the back of the tele that needed changing. I did try to this on my own but unfortunatley didn't have the right fuse so i took it to a repair shop and he done it really quickly.

This is most likely caused by the Main Power pcb.
See Fujitsu Service Bulletin on this problem in a similar model from Fujitsu. -see link below
A competent service technician should be able to implement the service bulletin.
A similar service bulletin is probably available for your model. Request bulletin from Fujitsu 'email@example.com'

Alas, the powerblock has gone.
Common problem on this model.
Only solution is replacement powerblock.
Pioneer used to repair this for nothing even out of warranty (they did for me), but they may not be so willing now, as your tele must be at least 6 years old. Unfortunately, it will be cheaper to buy a new TV than to pay for a contractor to fix it.
