SearsRoebuck Posted October 19, 2018 Share Posted October 19, 2018 (edited) Hey all, bought a Super Video Arcade recently and I am getting the dreaded black screen of death when turned on. About half the time when I turn it on I can hear a short low noise, a quick 'bummm' sound, but nothing else. The reset button seems to work properly though. Taking it apart I don't see anything obvious. Any one have an idea? Asking around and I was told it could be a bad ram chip. Sadly none are available on ebay though. At some point I am going to send this off to Crossbow for modding but I wanted to see if I could get it working before that to save him the trouble.

mthompson Posted October 19, 2018 Share Posted October 19, 2018 (edited) I was able to fix my motherboard by replacing a couple of the transistors. Here's the thread than documents my repair. I also sourced replacement chips that I ended up not needing. They're listed in the thread. I was able to swap some of the chips first from a good unit and eliminate them as the source of the problem. You should also check that you're getting the proper voltages at the various test points. There is also a cheap kit available to install new capacitors (link). In all, fixing these requires patience and experimentation. Start with the cheap & easy stuff first.

mr_me Posted October 20, 2018 Share Posted October 20, 2018 (edited) Inspect and clean the cartridge port. Test multiple cartridges. Check that the different voltages are getting to the mainboard correctly. You can find the service manual here. https://console5.com/wiki/Intellivision What do you mean when you say the reset button is working?
