So far I've removed all the boards I could that were relatively easy.? I have not touched the ones that are under a metal panel identified as A and then a number. A31 or A32 for example.
I'm no longer getting the several beeps sequence as before so something has changed. Noticed after examining the power supple boards. However the alphanumerics still do not display and the flashing dot on the screen remains.
No burnt components were noticed when examining the boards or even a hint that something was askew.
So, on to the next phase but that will be tomorrow.
thanks, Peter
