Re: Asteroids problem sorta fixed

Ok. I have "blooming" then. According tot he faq it says clean transistors
first. Those should be clean as they are brand new.

For quick reference, page 14

The HV diode, that is....?

A failing HV diode will cause ‘blooming’ of your picture. Arcing within the
high voltage rectifier
connectors causes this condition. To cure this problem, follow this
procedure:
1. Switch off AC power and remove the monitor from the game.
2. Remove H.V. cover secured by two screws.
3. Unplug the H.V. rectifier from its holders and inspect the holders to
insure that the springs
are inside the holder.
4. Replace the bad rectifier with a new rectifier. The leads of the
rectifier must be cut and
formed in the same manner as the original.
5. Insert the rectifier firmly in its holders, banded side toward CRT.
6. Inspect the lead dress of the transformer H.V. wire. Wire must be
dressed.
7. Inspect fuse F102 on main deflection PC board. The fuse value should be
1.5 amp.
8. Replace the H.V. cover, which was removed in step No. 2.

So I don't have to discharge the monitor to do this?
