Hi Guys, I'm in trouble with my HCL (HCM780M) monitor for the last couple of weeks n now request if any of you can give me a solution to it. The trouble is, immediately after getting connected to power, the control window of the monitor appears and it goes out of control of the monitor-buttons. No button can close or adjust any of the functions embodied therein. The indicator remains on 'contrast' button and then suddenly it begins to move one after another button speedily and after some time it closes automatically. As a result, the size of the windows sometimes gets vertical, smaller, sometimes brightness or contrast comes down from the normal ones. I'm using this monitor since 4 years. Is there any solution to this hitch?
