Re: Question re: WG 19K7901 monitor



Well I finally got up the nerve to pull the monitor and discharge it
myself (first time).

I looked at the chassis but nothing was noticebly wrong (at least to my
untrained eye).

I checked for continutity on the 110VAC lines (by manipulating the
wires while measuring resistance between various points) and there
doesn't appear to be any breaks in the power lines. I seem to have
continuity from the power source to the monitor connector to the down
stream side of the fuse on the board.

So here is what I'm left with:
When the monitor has been off for any length of time (couple of hours)
the monitor will not power up when power is applied to the game. There
is no glow in the neck at this time.

If you look at the left side of the chassis there is a metal piece of
the chassis that runs vertical to the circuit board (where the 110 VAC
power lines mount to).

If I apply a little pressure to this piece of metal, I will hear a
little crackling and the monitor comes to life.

I assume that I may be flexing the board ever so slightly by applying
pressure to this part of the chassis.


Any have any ideas or willing to take on this challenge for a fee? If
it makes any difference, I am located in Flat Rock, MI (south of
detroit).

In the alternative, does anyone know of a replacement chassis that will
save me the time of becoming an expert on the Wells Gardner 19K7901 (it
is couled to a Phillips A48ABK05X tube)?


Thanks,
Tim
