Monitor Samtron after 10min. looses contact with computer

I am using your SAMTRON 73V flat monitor 4th year. Several month ago the monitor did start to block after more than one hour time of use. The time of proper work did gradually drop down, to recent about 10 minutes, what is to short for doing anything. The blocking of the monitor appears as: moving round the screen a warring window with message 'not optimum settings, use 1280x1024x60Hz' by total lack of contact with the computer.
It is not possible to change actual settings using monitor keys.
After switching off the terminal for not less than about 10 min. and resetting the computer, the terminal can work properly next 10 minutes.
The optimum settings (shown in the warring window: 1280x1024x60Hz) of the terminal adjusted from Windows control panel do not allow to get proper work of the terminal in any future attempts.

This problem is caused by the Novatek chip on the video board. Soldering a 50 Ohm Resistor across pins 5 and 6 of this chip resolves the problem on both the Samtron and the Samsung monitors. I have just corrected one of these last night by this means.
Hope that helps

I am a technician.My Samtron 56 V moniter dead. Some time switch on when power is connected after 10to15 minutes. Please give a solution.


If you have Samtron 56 V monitor that sometimes switch ON for 10 to 15 minutes, then it is a signal of some internal device fault which needs to be rectified from certified hardware technician from monitor manufacturer service center itself. It is recommended to directly contact Samtron for hardware replacement if it is under warranty or ask to repair it.
