Question about Televison & Video
IF you use google you can find the service manual for that set, the ability to spot bad capacitors on the power board is not reliable. components can fail with no outward signs.

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…

If the power supply outputs are good! Then I would say the back light inverter is bad! If the screen stays black and does not come on.

Yes it does sound like the mainboard. But we have to confirm. I will see if there is a service manual for this unit in my collection but do you think you can safely work on it? Have you worked on electronics before? The last thing I want is you hurting yourself trying to fix it. HV circuits are not to be messed with unless you know about them.
