Monitor doesnt turn on


From your description, it sounds like the internal 5 Amp cartridge fuse is open. Will need to open the housing and inspect the fuse for failure. If located and failed, replace it and energize the monitor.

If the fuse fails immediately, you have a High Voltage power supply short and the monitor is scrap. It will cost more to replace the power supply/transformer than the monitor is worth.

Hope this provides some useful information.

Monitor flashes on then goes black.


I think you have the display shut off. the button on the bottom left will shut screen off. It will come on for a few seconds if you touch the screen, but will shut off again. just push the display button again and it should stay on.
