Thanks for all the responses so far. I have already gone over the board
checking solder joints. Actually that is the funny part cause the fellows I
work with say I must have microscope eyes since lots of the stuff we work on
I can pick out bad solder joints with one eye tied behind my back ;-)
I haven't really had time yet to check out the triac on the board or any of
the transistors and stuff. During the brief time I saw the board I just
happened to notice the chips sanded off so I thought I would ask if anyone
had a schematic so I can have all my info handy before I start working on it
later in the week. I have found places that sell the board for around $60.00
so if all else fails the owner can get another board. I'm on days off at the
moment and I'm back to work on Tuesday so that is when I will get my hands
on it again to start checking out the board at component level. Like I said,
I was just seeing if I can get all my ducks in a row beforehand to make life
a little easier. Thanks again folks.

Cheers,
Lawrence
