This is a very simply fix. Your problem is you have a bad thermal fuse. This fuse can be found in the Lamp housing. You need to take the back off in order to fix this problem. Replacing the thermal is not hard, but you need to be a little handy. Part number 1-910-023-93 Average cost $9.00

Ok here's how I manage solve the problem... Having the back removed opens the contacts on the interlock switch so I guess if it powers up in this state it senses the high voltages are exposed and for safety shuts down... After this the unit will not power up and the power led flashes red continuously as described before…
After some thought it occurred to me that there may not be a problem at all, just be a simple reset function for this condition… I managed to find an easy solution to this… Just call up the hidden engineer’s service menu – On 3rd generation Pioneer Plasmas it’s as follows > Power down the screen > Hold down the “Input” and “Vol +” buttons on the front > Power the screen up and the Service menu comes up on the screen > You don't need to change anything just simply power off and from then the screen should operate as normal…It did for me so I’m well happy now!!
I hope this information will help someone else one day – Good Luck!!…Rob UK…

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 appears in all cases that the power supply needs to be service. The blinking light might indicate that there are shorted parts or the voltage is low or a combination of both.
The solution at this point would be to get the power supply repair since new boards are not longer being manufactured. In about 95% of the time if the LCD doesn't power up or turns OFF by itself or need to be unplug for some time to make work again; those are the symptoms of a dying or defective power supply.

The TV is on protect mode.
Try first leaving the TV power cord unplugged for some times, let say one hour or so.
Also ensure that the fault is not coming from a faulty receiver box sending bad signal, check if you get same problem with no receiver box or dvd connected.
If that does not work, and you keep having a flashing led on front of the TV, and tv turning off by itself after a while, that indicates a fault condition.
The flashing light indicates a diagnostic state called protection.
When the TV goes on protection there are only two possible reasons.
1The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.
2 The protection circuit detected a wrong voltage or abroken contact, identified an internal fault and kicked in , startingthe flashing light.
If you are in situation one, then theTV will reset just unplugging power cord for one or two hours,sometimes even minutes.
If you are in situation 2 , then there is an internal fault.
Common faults that can occur are a blown capacitor on power board, a convergence IC has blown, or a fault on Digital board.
Check also the video cable or any external connection cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.
If under warranty contact the manufacturer ringing the number on the user manual
If you want to repair at your own expenses, just locate any good qualified repairer.
