I have on old bmc 20 1993 model with ultimax 3 dual screen control. It had a new power supply fitted over a year ago and the screens were also repaired, the screens are colour ones. When I power the machine up the text screen takes about 10 minutes to come on and then a further 30 minutes to warm up so that the text can be read.
I have tried swapping the screens round and it still has the problem with the text screen, the graphics screen works fine. This proves it's not the screens as the problem would follow the screen when I swapped them round.
I can't see how it could be a power supply problem as this was a new hurco item just over a year ago.
Any help? |
