42'' samsung plasma. no picture, sound only. Power supply board?

SOURCE: Pioneer PDP 5030 power supply problem

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…
