Hi Turnip,
Yes it is the same board! I have changed the diodes and checked all the smd's on the underside but fails with the red led light flashing all the time but with no sequence, when i apply a little heat to the IC it powers on ok, freeze the chip and inverters switch off! Sadly can not find chip any where so looks like a board change. Many thanks for the reply

Hi Robbieh,
Have panel with IC7 (D78F9222CX) Flash memory programmer. My fault is a little different so if you could use panel or chip just say the word - Just postage - Chris.

Hi Chris,
Have sent you an Email would be pleased if you can send the chip or board complete will pay you for postage packaging and what ever you want for the board as it will be a cheaper option for the customer.
Sorry if i have hijacked this thread
