sideburn Posted January 14, 2016 Share Posted January 14, 2016 Can someone please answer me all or even just one of these questions: Should the picture tube be lighting up even if logic board is disconnected? What voltages should I see on back off crt and near the high voltage transformer? If this is not the place for tech help, is there another vectrex forum where I can get some troubleshooting support? Thanks! I am desperate for some help trying to repair my vectrex. The picture tube is dead but I'm seeing voltages that look correct so I'm wondering if the crt itself is bad. I got no replies from my first post so I guess this one will be my last try Quote Link to comment Share on other sites More sharing options...
+madman Posted January 15, 2016 Share Posted January 15, 2016 Have you looked at the service manual? It should cover all necessary voltages. Quote Link to comment Share on other sites More sharing options...
chas10e Posted January 15, 2016 Share Posted January 15, 2016 Have you looked at the service manual? It should cover all necessary voltages. http://www.ags.tu-bs.de/lib/exe/fetch.php?media=web:e.lab:projekte:vectrex_manual.pdf there is also Vector gaming forums http://vectorgaming.proboards.com/ I'm hoping mine never breaks .... Atariage does have many good techs & I hope you find the help you need Quote Link to comment Share on other sites More sharing options...

Things to check - Power supply volatges, 555 timer, High voltage transistor. Quote Link to comment Share on other sites More sharing options...
