I'm looking for some ideas on what to check in my VPH722Q1. It has a periodic brightness surge . I haven't timed it but is becoming more frequent, about every four or five minutes the brightness surges on all three guns. any ideas would be welcome.


Thanks

Al,


I'll bet you have a dirty edge connector on the video board that stands between the blue and green tubes. Pull the board out and clean the contacts where it plugs into the mother board, and that'll fix it.
