Heidenhain TNC151 problem

Typically, just when you get busy, something goes wrong .............
The controller on one of my Bridgeport mills seems to have a fault with the
display or graphics output. No output, no display on the screen. Screen
checked by a specialist , all working.
I do have an offer from the same company that checked the monitor, to have
the board checked and buffer chips replaced if that is the problem, but it
could be something else.
Just wondered if anyone one the group had one of these controllers lying
around, or parts from one that busted , but with a different fault to mine.

If he was a specialist how come he can`t fix it.The cnc repair business is full of specialists.Less than 20% know what they`re doing.

A Bridgeport Interact CNC Mill I have has a display problem. Its not the monitor, that's been checked and it works. Next thing to check is the graphics card. Problem I have, is which card is it ? there are 4 in the controller, one is obviously the axis control, as its marked x,y ,z, etc.Anyone know which of the other 3 it could be? there are no obvious cables to or from the monitor to the boards.

Can't tell for sure. But if one of the big 40-pin chips on one of the cards is a 6845 (or MC6845 etc) that'll be the graphics card.

Go to Heidenhains site and download the manuals.One of them tells you which board is which.

That link to photobucket brings up an annoying popup on my screen.
