thanks for response, will try that. At the time of your reply it has returned to normal (for the moment- as it reverted to normal for about 10 seconds shortly after submitting my post onto the forum). Do you still think it's the 'gun'?
pink screen is a lack of green drive, check seating on graphics card, if anyway technical (if not do NOT attempt this) remove the cabinet and tap around the tube base for possible dry joints etc, also check connecting cable from pc to monitor by unpluuging and re plugging.
only my points re cables to monitor or the crt base in monitor but ONLY if you are technically competent or if you know someone you could as them to check for possible dry noints in the green drive circuit.
Hi griffo. I occasionally get this same problem. In my case it is caused by the monitor cable being kinked where it exits from the connector behind the base unit. If the computer is pushed too hard against the wall the cable is compressed, presumably causing a partial breakdown of the insulation.
