Sounds like a capacitor in one of the power supplies exploded either in your high voltage horizontal power supply or the main power supply. If you don't mind taking off the back cover you actually might be able to find this capacitor it will have a huge hole in it.
Capacitors tend to dry out after about 5-6 years and can explode just like yours has.

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…

Have ordered a new power supply PCB as too many parts need replacement. Best to buy the whole lot.
Ventilation seems to be an issue with this unit, I am thinking of installing a small fan at the back to cool the voltage regulator and main transformer.
