Thank you so much for your input Gunrunner John. I was hoping you would read my post.
Can I ask, have you read my current thread about the running problems I am having with this loco? (Can I do a factory reset using my Z 750?)
As far as I am aware, there is no one in Australia that I can send the board to for testing. I'm all on my own here, "down under". That is why I figured it will be much simpler to just buy a new PS3 board (if that's all I need) and install it myself, but GGG said in the other thread I may be waiting another year before a new board becomes available to me.
If worst comes to worst, can I send this board over to you for testing?
Having asked that, I don't know where we would go from there if it is a bad board.
Anyway, thanks again for your help/advice with my problem....I really appreciate it.
