Hello,

I am having problems with a Hurco BMC 2416. The monitor will go to sleep after about 20 minutes and the screen goes black. The control is an Ultimax SSM. I try pressing all of the keys on the control and the screen will not come up. I can cycle power to the machine and sometimes the monitor will come back on some times I have to cycle the power multiple times for it to come back on. I am running a bigger pc monitor on the control which has run great for years. Sometimes when I power the machine up the monitor will be solid red or blue or sometimes green. I have tried to running different monitors and come up with the same problem. Could this be a graphics card problem?
