The screen lights up and the beam is steady and can be centred using the R/L U/D controls. The fans fun quietly and a one hour test shows no change in display stability or any overheating. I do not know how to use this unit so cannot test its operation.  I assume there is some fine tuning or switch cleaning required as the beam wanders when using some of the switches.
