RE: Major Havoc Screen problems

Thanks for the info. I have got the WG 6100 and I just used Bob Roberts
basic kit and additional kit on it to get it up and running again. If I
check the 180vdc pin5 on the HV cage and it isn't 180vdc, then what do I
need to do? Should I be adjusting the HV pot? Do I use that 180 vdc to
guage how much to adjust? Or do I adjust the HV trip pot? My WG has the
newer HV board (P316 - HV), P327 for Defl, and P328? for Neck.

BTW, I am not really sure as to where Pin 5 is on the HV cage. Ar you
referring to the red connector going into the HV unit?

Thanks

This could be blooming caused by low high voltage. What kind of monitor are
you using? If its a WG6100, you should be able to check for 180vdc on pin 5
of the HV cage. If you are using an Amplifone, you should be able to check
one of the secondary windings on the HV transformer (it isn't red, is it?).
Btw, if anyone cares, you can also set the HV on a G05 by either using the
90V (B+? - I don't have my schems on me) and the 400V (focus).

This could also be a problem with the HV diode. This is a very common
problem with G05's.

that, made adjustments and started to play the game. While I was playing
(about 15mins), all of a sudden the picture expanded on the screen such that
objects were way off the screen that I would normally see (almost like I
zoomed in on a part of the game - or as if I had adjusted the x & y size
pots. Anyhow, it was like this and I rebooted back to test mode to
re-adjust and could not shrink the screen back to the correct size (it was
still way to stretched). I also lost the red border around the tests
screens as well and the nice smooth shrinking box no longer is smooth.. it
skips sizes and just disappears and appears as a smaller box like it is in
jerky movement mode.
