I bought a used vectrex off ebay. The guy shipped it very very well and did a wonderful job. Have one problem. When I turn it on, the words are garbled into funny horzontal lines. There is a white dot in the center. And every dot or line is connected to lines that run to the center screen where the white dot is. Been trying to figure out how to repair it but not have had any luck finding the solution to my problem. Any help will be much appreciated. Can make a youtube vid to show my problem if it will help.
