Hello friends.

I am sending out an S.O.S to the world. We´ve been stranded here for a while with a MAZATROL T1 turning machine, If anyone could help us out it would be greatly appreciated.

Please take a look at the attached picture, That´s all we are getting this far. "CPU DOWN"

One of the operators told me that he finds intriguing the fact that the CRT comes ON inmediately right after we turn ON the main switch. He says this was not like that before. It used to be needed to press the POWER ON membrane key in order to get something from the CRT. Now it does it on its own .

If at least could have a good UL52C MELDAS YL book I could try to advance a bit more with the Troubleshooting. Any help will be greatly appreciated.
