WG 6102

WG6102 (P327, P328, P329)

I am almost done with my Tempest cabaret restoration, but am still fighting
with the monitor. Depending on the monitor's mode, it may or may not
turn on when the game is powered on. However, a good wack to the
side of the cabinet will usually bring it back. Obviously, this sounds like
cold solder or a loose connection. I believe it's in the HV unit, but
for the
life of me I can't find it. I resoldered all pins, cleaned the pins on
I could
the row of pins, but the molex plug, etc. Can't find any burned or
damaged components on the board.

Here is what I know:

- Even with the picture off, there is still loads of deflection chatter.
- If the monitor is off, the tube itself doesn't crackle. However, when it
   turns back on I hear the normal crackle. If the monitors turns on when
   powerd on, I also hear the normal crackle.
- With the monitor out of the game, and when the picture is on, I can very
   lightly tap the top of the HV cage and it turns off (but deflection
chatter
   can still be heard). If I tape the cage again, it rarely turns on,
but if I
   hit (wtih some effort) the side of the frame, near the top, that the
HV unit
   is on, the screen will usually flash the image for a moment and fail
again.
   If I do this enough, it will eventually stay on.
- I have NOT done a cap kit on the monitor yet, since I am still trying to
   get the "correct" list of parts together for this monitor (it's a
true 6102)
   and I know there has been discussion before relating to what is the
   correct parts, what's not, whom sells it, what they sub, etc., etc., etc.
- Testing the HV, under the cup, shows 20Kv and it climbs a little if the
  monitor is on about a minute or so. My HV probe isn't the most
  accurate and tends to fluctuate slightly (about .5Kv or so).
- The other problem I am seeing with the monitor is a curve across the
   bottom of the screen and shaky vectors. I know the shaky vectors
   are usually a missing HV cage (mine is present) or bad caps at 901,
   902 and 905 in HV unit. However, I'm not sure what is causing the
   curve.

Anyone have any ideas?
