I brought a Vectrex a while ago as fully working...
And when I tested it it looked fine. But if the unit is left on for more than 30 minutes or so the screen picture starts to fluctuate in size (gets smaller then bigger).
Anyone here know what's up with it?
I had exactly the same problem with one of my vectrexes...
It seemed to work ok when I checked it, but after about 20-30 mins of playtime the unit started going berserk and the image was shrinking...
A complete recap was the solution for me.
I'm not sure if it was a bad joint or a bad capacitor...but the recap solved the problem for me.
If the problem is not solved after the recap then you're in trouble, since its probable that you have a faulty chip on your vectrex....
now as for the initial question of the thread....
Apart from the cosmetic condition, you should definitely check that the controller is auto-centering. As already mentioned vectrex controllers are expensive...so you wouldn't want to get a faulty one with your vectrex.
If you have the luxury of picking up the unit and checking it yourself....let it play for 30 mins and check for any weird behaviour of the screen.
