Question about SAMTRON 55V 15" CRT Monitor

1 Answer

Controllock All of a sudden, my monitor (Samsung-Samtron 56V) features--brightness, contrast, etc.,-- are appearing on the screen by themselves. They keep flickering on and off, lock and unlock ControlLock and do not go away even with repeated pressing of the exit button on the monitor. Keeping the exit button depressed even changes the display width, and contrast.

Its aproblem of command section.Check its components one by one.you can identify this section (the front panal buttons goes in this section and a ic in big size and pasted horizantally in the circuit).if the components are ok then change command ic with new one.This will solve your problem.
