Barry,
Maybe you should ask the seller of your board for a pin out.
I don't know how much you paid for it, BUT, for the aggravation you are experiencing ......just get something with information and move on.
Long time ago helped a young lad get a TB?
working ....took hours.....what a pain and never /ever again. That's why I won't even assist with that junk.
Something to think about,
RICH
