Hi..got a problem with the samtron 45bn monitor. Initially, the screen turned yellow, then afterwards the screen went blank ie. black altogether... the monitor switches on alongwith the PC but remains blank..guess its a cable problem..plz help..
..checked the cable and found it to be alright..guess the internal circuitry has locked or something as the light in the front panel is always on..how do i go about repairing now..

Sounds like your video card went out simple check of this
if you have another computer that works hook it up to its computer if screen comes on it will be your video card in the comp now if the screen still doesnt work it will be the cable the pins in the end has some how bent or come loose this will require a service tech electrician to repair simple quick job

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.

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.

Samsung 45bn H output transistot over hating and burning out after a fewminits


THE MOST ECONOMICAL SURE FIRE FIX IS TO REPLACE YOUR MONITOR WITH A QUALITY LCD SCREEN IT UTLIZES 50% less electricty AND RUNs A LOT COOLER.

IF THE HORIZONTAL OUTPUT TRANSISTOR IS BAD MOST LIKEY THE POWER CONTROL BOARD IS GOING BAD you may also have a bad resistor or diode allowing to much current on power control board
