Free Vectrex Parts Machine local pickup in South San Jose
Title of thread explains it all. Tube glows when powered on, but only a single dot displays on the monitor. No joystick, and only 1 screw for the back of the case. First come first serve.
I'm curious too. I tried fixing one for a friend and recapped the entire thing and it still didn't come back. I'm guessing the tube was good but the mainboard was bad.
I was just testing the vector tube with my Zektor ZVG board, which shows it working (that is Tempest playing) although may need some adjustment. The mainboard is still dead...something I'll try troubleshooting later...for now this is my new Zektor test monitor.
