SnapCraft Posted April 17, 2011 Share Posted April 17, 2011 Here's a problem I haven't seen on the boards: When using the test cart (or Kelly's cart ), I can't go up/down on Joy1. Joy2 makes Joy1 go up and down when Joy2 is moved in a circular motion. The joysticks are fine. It's something on the base board. I re-soldered the 9-pin joy ports. Nothing. Suggestions? When I first got this I had the semi-famous super bright dot in the middle of the screen with the "webbing" and horizontal lines for text (no, it wasn't the brightness knob). I did the tip of replacing with a Vic-20 6522 chip and it worked. Only to discover the sound didn't work. I noticed one of my re-caps was on backwards , fixed it and now have sound! I can't give up now. This baby is almost back to life! Please help! Quote Link to comment Share on other sites More sharing options...
VectrexMad! Posted April 18, 2011 Share Posted April 18, 2011 Left/right joystick is on pin 6 Up/Down is on pin 5. So check connections to those pins. And also pin 7 (+5V) and pin 9 (-5V) which are connected to the joystick. Sorry maybe a silly question, how do you know that your joysticks are fine? If I remember rightly, if there is only one joystick connected, one of the graphic boxes will light up for the other joystick because of pull up resistors inside the Vectrex. I believe that was stated in the service guide or trouble shooting guide. Quote Link to comment Share on other sites More sharing options...
