Hi Guys,
Every now and then the control throws up a garbled screen or the one in the picture below.
It always happen while the machine and control is under power.
Usually I just reboot and everything is fine. On three occasions it did not work to just reboot and then I get the below system label check; ERROR.
After this I go through the zap memory, input options, restore parameters etc. and that works fine. I would now like to find out what needs replacement to stop this from happening. The control does not have bubble memory and I doubt it has anything to do with the back up batteries as they test fine and as the problem occurs while the machine is powered up. The IPL screen says; END after checking ROM and RAM. Assuming that means OK I guess the memory module is OK. So what should I repair or replace?
All the best,
Andy
