now the red light blinks 8 times.

Hi

My TX-P50GT30B has decided not to power up.

The red light blinked 7 times.

I very carefully removed the "Y Sustain Board" having researched into it a little,

powered the TV back up and now the red light blinks 8 times.

Can anybody shed anymore light onto what I should do next?

I have emailed two Panasonic certified TV repair shops (its past office hours on a Friday right now so I cant call, just my rotten luck lol)

I really would like to breathe new life into this TV because I enjoy the picture quality on it so much.

Any help will be greatly appreciated,

Kind Regards,

Dave
