TorinV Posted May 22, 2014 Share Posted May 22, 2014 I recently bought two genesis systems on eBay, and both have had the same issue. When using Rf as the output, it displays a black screen with moving white lines and what looks like the game between them. When using the DIN connector to composite, there is no video signal. Both consoles have had the same issue, with the same black screen and lines. I've tried different games, TVs, RF adapters, and tried cleaning the slot. No luck as of yet. Has anyone else had this issue? Quote Link to comment Share on other sites More sharing options...
Zthun Posted June 19, 2014 Share Posted June 19, 2014 I had this issue. The problem was the power adapter. Are you using the official genesis block with the correct voltage. I had a 9v NES one on mine and it didn't output any video until I replaced it with a 10v adapter. I now have a problem myself with the system crashing, but as to the video problems, changing the adapter fixed the issue. Quote Link to comment Share on other sites More sharing options...
Osgeld Posted June 20, 2014 Share Posted June 20, 2014 NES uses AC, genesis uses DC, lucky you didnt fry the system, may have something to do with your crashes Zt but yes try a different DC adapter 9-12 volts should be safe Quote Link to comment Share on other sites More sharing options...
