I recently did a monitor swap on my Q*Bert. I removed the original WG4900 and replaced it with another WG4900 that had a tube-swap done on it. The picture on the new, tube-swapped monitor is great, however, when I turn on the game next to it, I now get some interference.
Here's a pic
The line shown moves from left to right over and over, towards the game that appears to be causing the interference.
The game to the right (the one presumably causing the interference) is a Vs. Unisystem running various Nintendo boards and a Sanyo EZ monitor. All the boards are in RF cages so I'm guessing the interference is being caused by the Sanyo.
I note that the old WG4900 did not seem to be affected.
Does anybody have any experience successfully eliminating this type of thing (aside from physically moving the cabinet to a different location)?
I was thinking about possible solutions (other than physically moving the cab) and came up with:
1) Swapping out the chassis on my new monitor with the original chassis (the old monitor didn't have this type of issue, however, if if this problem is linked to the TUBE, then the chassis swap would be pointless.
2) Buying a roll of RF shield and lining the inside left of the Nintendo cab with that.
3) Lining the right inside of the Q-Bert with the RF shield.
