Do you have a location for the service manual? I haven't had much luck finding it.

Most of the numbers are going to be a Panasonic assigned number, some are real but all those "B" numbers are only useful if ordering direct from Panasonic.

So have a look at the device and the markings you can usually work it out, google etc

J281 will be 2SJ281(Sanyo)

Ok changed the diode and resistors now we are down to a 5 blink code which is the 5V SOS. I have been unable to find the Mosfet 2SJ281 I have checked the datasheet but am unable to find ant suitable replacements.

Unplug SC see if it goes back to 6/7/8.
5 blinks can be PDP fault.

The plasma display panel, i.e. the glass, not repairable. It is unlikely though just something to be aware of.

Update received the Mosfet and replaced it still no change. 5 Blinks. When I plug it in I hear a few clicks as it is attempting to power up. When I hit the power button it buzzed/hummed (not very loud) for 3 seconds or so then clicks again and goes into shutdown mode.

I feel that it is something around the burnt spot in the board because before I started replacing components on the SC board it had 7 blinks. I wish I could find a SC board for this but it appears to be a popular item and not available anywhere.
