RE: Tempest Spot Killer On w/ LV2000 and Zanen 206.

Arthur,
        Glad to see you made it over here.

First of all, I would say that the D100-D103 and Q901 and Q902 are all OK.
(since you are getting +/- 26V and you can see a dot when you turn up the
brightness)

Use your multimeter and check the x and y outputs from the game. You should
see a DC voltage close to 0, and an AC voltage of something (sorry, can't
remember about where is should be). Basically, if you get an AC voltage of
0, or a DC voltage that's stuck on some value that's not real close to 0,
then you probably have a bad output section on your game board.

Subject: VECTOR: Tempest Spot Killer On w/ LV2000 and Zanen 206.

Hi All. Got my new cocktail Tempest, and had a blast for 1/2 hour until the

monitor went out. Spot killer on. Right voltages on fuses. Chassis
transistors not shorted - +/-26V.

Installed LV2000, both LV2000 LEDs on. Spot killer still on. Turn up
brightness, blue dot in center of screen.

Per, www.amug.org/~necro/video/zanen206.html, installed the Zanen kit, and
extra components (minus chassis transistors - and minus D100, D101, D102,
D103 deflection board, and Q901, Q902 High Voltage parts (on backorder)).

F700 blew on power up. Spot killer on. Replaced fuse, didn't blow again.
Spot Killer still on. Turn up brightness, blue dot in center of screen.
Rexamined all components; nothing obviously burned. F700 still good.

Offer any ideas? Or wait and replace the D100-D103 and Q901, Q902 before
going into serious troubleshooting?
Thanks, Arthur.

p.s. This is my first post; is this list described/referenced on the web;
are previous messages available? Surely someone else has had this problem;
but I can't find a troubleshooting on F700 anywhere (sure, all the other
fuses, but not F700).
