P2000 monitor issue

[pinball god]

Just started occuring. My Monitor on a pin2000 seems to have a slight PINK tinge to the whites. When I go to the diagnostics section and use the 4 push button switches I notice the white colour kind of flickers between white and a red/pink. Short of using NAPPYSAN (as I know someone will suggest this as a solution), what areas should I be concentrating on or is it just a matter of replacing the monitor?

Sounds like a chassis issue but having never actually worked on one id wait for further advice

I'd email Joey @ JOMAC.  If he doesn't know the cause/fix no one will.

Has it changed orientation at all (ie have you swapped the pin from one side of room to other?)...May also need a degauss.

Is there anything you have moved next to the machine that may be interfering ? Check with Jomac - it should be a simple fix - no need to replace anything, Rob !

Sounds like a drifty voltage (or ground connection) that feeds your RED drive transitor, each time you press the button it 'normalises' the voltage (or ground) so the tranny drives a normal WHITE colour and reverts back to pink when you stop pressing the menu buttons.

Sounds like some kind of unregulation (filter cap) for the volts that goes to the driver trannies.

A quick fix might also be to remove the neck PCB off the rear of the tube, and re-fit it, those poins can be intermittent/corrosive due to the high voltages pumping thru them.
I fixed monitors for 25 years, and have seen a lot of weird faults, yet i'm sure there's 1,000's i havent seen yet hehehehe

Food for thought.
