If it's still under warranty I would call for repair service. It sounds like typical internal power supply trouble that needs electrical troubleshooting.

SOURCE: To open the Samton 45Bn crt monitor

turn off power.

Get a long philips screw driver and remove the base and all fixing screws. some are hidden behind blanking plates and the com off with a sharp knife and a getle lifting at the join.

After all screws are removed the lie the screen downwards and start to pull away the backing.

you should get the case apart easily.

You must be aware of the tube holding a full charge at its end. DO NOT touch this at any point. The only thing you should try to inspect is the fuse or adjustment to the focus slant contrast etc.

Problem in Samtron 45Bn Monitor


Try connecting the monitor to the mains instead of the UPS.
If it works OK then the problem maybe the UPS and that it is very close to the max output of the UPS.
If not then the monitor is faulty.

When I switch on my computer, Windows XP start loading and then my Samsung Samtron 45Bn monitor's screen goes blank and the green light keeps flashing every 0.5 secs.


It sounds like your video is set to the wrong resolution. Try booting into safe mode by pressing F12 at the start of the boot process. If you get into windows that way, then adjust the display to something you monitor can display like 1024x728@32bits. The monitor can only display a certain amount of pixels and if you set the video card to high you will lose visual. Hope this helps.
