Managed to score a Vectrex of eBay back last week, paid £70 for it delivered and whilst its not in excellent condition its accpetable or though there are a few issues with it. The on/off/volume knob is a bit temperamental, sometimes when you click it to the on position it doesnt turn on and you have to fiddle with it a few time for it to actually turn on. The other problem has only started happening in the last day or so, it actually started to happen after i put the Vectrex back together after taking it apart to clean the inside as it was abit dirty, i didnt touch anything inside at all. Now it would appear that it takes a good few minutes for a picture to actually appear on the screen, at first after putting the Vectrex back together i thought i had completely buggered it but after a few minutes of turning it on and off a picture appeared. Tried it again this morning and no picture again until leave it turned on for a minute or so and then got a picture, any ideas what is causing any of these issues??
