Hello EDAians,

I have one patient monitor from Schiller. The day i switched on, the color lcd screen began to flicker...continuous..but i could recognize the background. I charged the internal battery for 4 hrs. Again i switch on, it worked for 5 minutes with clear view...but again the lcd began to flicker...
Sometimes the screen goes black...sometimes its goes white...the band of color flickers...i.e. there is some problem with the lcd screen.
Therefore my question is: What may be the problem...how can i make it work properly. OR last choice is to return to the schiller and make them to mend the problem.

Best Regards,

If Monitor is not working on main then there may be problem of connection between Mother board and LCD
