I used the trouble shooting chart you give me before and with ss2 and ss11 unplugged when I done that it give me 7 blinks, so I replaced the SS board and with them 2 unplugged it's still giving me 10 blinks now, I followed the chart after that, but after unplugging p35 it asks if the tv stays on but with code 10 the tv doesn't come on at all...

Not sure if we're making any progress here. So you took the SS out of the equation and it gave code 7.
This is the error code for the SC (& SU or SD) but you say you've tested the SC using a shorting link on SC50. Did you lift SU and SD completely away from the SC - no need ( and not wise) to remove the flexies that go to the panel from SU/SD?
 If you remove connector SC2 and reconnect all else, does it still give code 10. IF no, then I'd blame the SC. If it still gives code 10, then unplug A11 and power the tv on. If code 10 persists, I'd say A board faulty, otherwise the P board.        Bruce

 Sorry, no Skype.......we're a tad antisocial in the colonies, lol. I have uploaded the service manual for you to "Plasma Service Manuals" in the download section of this forum.....a bit of light reading.

I'll also send direct to you some info on A board testing and the complex start-up sequence .....different models but same principles.... only cos I can't upload Microsoft Word docs to quuq.      Bruce

Hi Gilly, That's a curly one. Code 1 is an unknown SOS and does not point to a specific area at fault. Code 6 is a scan board SOS, usually the SC board but can also be the SS board. All you can do is check for a short across the 2 pins of connector SC1 both ways - normally 1 high and 1 low. If that checks OK check the SS board for shorted FETs/diodes.                                       Bruce
