Hi,

I have an original Asteroids tabletop machine. It works fine except after it has been on for a while the screen image seems to expand so that the scores and bits round the edges move off the screen.

Anyone have any ideas about how i can get it sorted? I live in the UK btw.

Cheers,
Anthony
 
Sounds like the monitor needs to be recapped. Just e-mail Bob he can set you up with the parts you need. Since you are in the UK you may want to order additional parts just in case...so you don't have to pay more shipping later.

Oh and Wecome to the boards!! ;)
 
Actually it sounds like it's blooming - picture is expanding. The fix is to replace the high voltage diode. It's either going to be a little box near the flyback, or a cylindrical piece in line with the anode wire (high voltage wire).

While you have it apart though it IS a good idea to cap it - $10 goes a long way to keep that vector shining.
