Check the pin # 1 of video input cable { broken or Bent }
if it is ok then there must be a problem with the cable or RGB Processing Circuit { Normally Dry Soldering of a faulty IC in the circuit of CRT BASE} .

Hi, I have compaq 7540 monitor 17''. It is showing only part of the screen and when I shake the monitor or plug it displays full screen for a second and gets reverted. Please help on this issue.


Sounds like you have a bad connection somewhere inside the monitor or cable. Try using a different cable (if possible) or trying a friends monitor. If it works fine, then you know that's your problem. CRT monitors are very inexpensive nowadays, and you might be able to find one at a yard sale or thrift store for pretty cheap instead of trying to get it repaired. Hope this helps!
