Answers :

If you still have the monitor, check the signal cable -- wiggle it a bit at the PC end and at the monitor end, while watching the image on the monitor. Any change? If you have issues when moving the cable at the PC end, you may want to try shutting down the PC and disconnecting the monitor. Then clean the pins on the monitor's connector with 91%+ isopropyl alcohol and a cotton swab (make sure no cotton is left behind). let dry and try again.

If none of this make any difference, wait for the monitor to go dim. Then, gently smack it on all sides. If the image clears up or changes, there is likely an internal bad connection. Do not open the monitor unless you are familiar with all safety precautions involved.

I have the same monitor and I was having a similar problem. Turned out, there was a cracked solder joint on the signal board at the back of the CRT plus several more questionable ones.
