Hi,
For the last one week my monitor was blinking once in a while and yesterday my monitor after two or three blinks with "zzzz" sound, the display suddenly shrunk (as if squeezed from the sides)..I couldnt correct it with the property settings on the monitor.the display area has become almost half the original size. Can you tell me what might be the reason? Mine is a LG 15" monitor bought 3 yrs back. Can I correct this or do I need to go to the Service center? Can I get it serviced from a local repairer?

Thanks
Vijay S
