My monitor is showing concave picture. In the begining, I used to wait for a few minutes, give some blows on its top...then it used to set back to normal. I thought that was a temporariry problem. But, I see this every time I switch-on Monitor. Moreover my trail and error methods(blows on top) are not working anymore.
Anyone please please help me in fixing this error.

off mode in 5 sec,problem represents that the data cable is not properly connected or the monitor is unable to recognize the connection once check your key board lights above the num pad when you switch on the PC if the lights appear . Then the power supply is not provided to only the monitor unplug the data cable and plug it again properly,even if doesnt solve your problem just shake the data cable receiver pin located to the back of the monitor.
If the lights on the keyboard does not appear the problem is within the cabinet it may occur due to the dust too,so clean it properly , using a hair drier for blowing the dust is better.
