I have a wells gardner V2000 B/W vector monitor in my game and it appears that the deflection board is a G05-802, I know that the HV board is a v2000. Is this causing my problem?

See picture.

another note

I installed a Bob Roberts G05-802 cap kit and everything was the same except on the HV board one cap did not match so I replaced a like value on the HV board and left the listed cap alone.

I also have an Asteroids DLX with a G05-802 in it and tried swapping the deflection board which was identical in parts to my BZ deflection board but the pinouts were different.

What is going on here....there doesn't appear to be any hacking it all seems factory built.

Here is a pic of my deflection board....easily identified as a G05-802. But my HV board is easily identified as a Wells V2000.

I've mixed and matched V2000 and G05 parts in the past with no issues. They are (almost) identical. Your problem looks like the brightness is up too high. Turn the brightness pot down a little.

That's exactly what I thought when I first saw the pic....and I've seen those pots go bad causing them to go full bright and unadjustable too.

Try adjusting the brightness/contrast and see if that helps.

Issue

I agree that is a brightness issue. There is one pin different on the v2000 and the 802. Some people move the wire over in the connector and some people just bend the pin over. Completely interchangeable.
 
On the contrary, the monitor is waaay dim. The picture doesn't do it justice. I have tried to turn it down, but then you can barely see the graphics and the trace lines are still there. I'm pretty sure the Z section is wasted on the deflection board or maybe the brightness pot has gone south.

I think I'll change out the Q504 and Q503 and if that doesn't work then I'll do what is stated in the G05-802 FAQ manual and pull the D504 off the board.
 
Can anyone decipher this text? I think what it is telling me is that if everything is o.k. and the brightness is still low, then de-solder the LED D504 and then I should have a good bright picture? This is from the G05-802 FAQ manual.

Spot Killer
The Spot Killer does not seem to cause much trouble with the exception of the LED, D504. It
cannot be checked by the usual ohmmeter method because it reads infinite resistance both ways.
If your dipswitch test pattern does not want to come in, or your brightness just doesn't seem bright
enough, and EVERYTHING EVERYWHERE else checks good, pull out D504. Chances are you
will have plenty of brightness.
Poor brightness with retrace lines could mean a defective D504, or perhaps the "Z" signal wire is
not connected properly to the base of Q504.
