ianoid Posted May 25, 2018 Share Posted May 25, 2018 I have a 4 switch with Rev 14 motherboard. When i start it up a get a black screen. Not the usual fry screen of a dirty cart connector. I suspect it's something else. It's a relatively clean unit and the cart connector looks OK, What do you guys suggest I start with? I have a multimeter to work with but I would need specific direction with it. And I can solder and desolder stuff as needed. I don't have a spare unit off hand to swap out parts. Might be able to dig up a harvestable Jr. Quote Link to comment Share on other sites More sharing options...

ubersaurus Posted May 26, 2018 Share Posted May 26, 2018 Best Electronics sells the ICs, which is probably a good way to go (especially if you can grab any other spare parts you might want). 1 Quote Link to comment Share on other sites More sharing options...
ianoid Posted June 3, 2018 Author Share Posted June 3, 2018 Harvested from a non working unit, tried the TIA no dice. Then I tried the RIOT and it worked! Thanks! Fun! Quote Link to comment Share on other sites More sharing options...
