Dauber Posted November 13, 2017 Share Posted November 13, 2017 I did an AV mod on a Sears light-sixer. I've done this mod many times on a 4-switch Vader, a couple of Jrs., a heavy sixer, and at least three 7800s....but this is a rare occurrence of a mod not working. I get no video, but when I turn the console on with a cartridge in it, I get to short buzzes in the key of B-flat (50hz??), almost indicating that it's some kind of POST that didn't go well. The console worked fine before I modded it. I'm attaching pictures of my external solder points; I'm not concerned about the leads to the audio/video jacks...but if anybody can give me any pointers, that'd be great. It was this mod: http://vintagegamingandmore.com/installation-guide-6-switch/ Quote Link to comment Share on other sites More sharing options...
Shawn Posted November 13, 2017 Share Posted November 13, 2017 Did you remove the transistor at 202? Quote Link to comment Share on other sites More sharing options...
Dauber Posted November 13, 2017 Author Share Posted November 13, 2017 Yup. First thing I did. Quote Link to comment Share on other sites More sharing options...
Dauber Posted November 15, 2017 Author Share Posted November 15, 2017 FIGURED IT OUT! Just out of curiosity, I did a search for other instructions on how to do an AV mod on a sixer. I found a set of instructions that were virtually identical -- the mod board looked slightly different but had the same components and wiring. Thing is...those instructions tell you to wire the audio-in to the main board, but the ones on vintagegamingandmore.com have you wiring the VIDEO-IN to the main board. I had enough time this morning to futz around...I swapped the audio-in and video-in, and the console works great now! woohoo! (I also posted a comment that hopefully vintagegamingandmore's moderator will notice so they can make the necessary correction.) Quote Link to comment Share on other sites More sharing options...
