DistantStar001 Posted March 19, 2019 Share Posted March 19, 2019 I was recently given a second Magnavox Odyssey 2, and it won't load any games. I know the cartridges are good and clean, as they work perfectly in my original unit. This "new" one, on the other hand, only gives me the bios or a black screen. I reset the pins and cleaned them with alcohol. Everything looks clean and aligned. The reset button seems to work as the screen flashes when I push it. I even took it apart and cleaned what appeared to be some corrosion off the traces near the cartridge port. The board looks clean, and I didn't find any unwanted continuity between traces, but the game still won't load. Any ideas? Quote Link to comment Share on other sites More sharing options...
metarog Posted March 21, 2019 Share Posted March 21, 2019 You can try swapping out the two socked chips on the motherboard. They are the 8048 and the one right below it. These chips do go bad from time to time. Quote Link to comment Share on other sites More sharing options...
DistantStar001 Posted March 21, 2019 Author Share Posted March 21, 2019 (edited) What is the chip below the processor, and where can I find a replacement? Also, on the few repair videos I've seen, there's a common mod where a 0.1mf ceramic capacitor is soldered to the underside of the board connecting what appears to be two pins on the processor. From what one of the videos said, this was done because the 0.01mf capacitor on the top was insufficient to guarantee the proper functioning of the processor and prone to failure. Could this help in my case? Edited March 21, 2019 by DistantStar001 Quote Link to comment Share on other sites More sharing options...
metarog Posted March 21, 2019 Share Posted March 21, 2019 It is the 8244 Audio Video chip. You will probably have to pull it from another O2. Ill check to see if I have an extra one. Ive already sold 2 of them in the past. I havent heard of that issue and mod but if you do find out please let us know. Quote Link to comment Share on other sites More sharing options...
DistantStar001 Posted March 22, 2019 Author Share Posted March 22, 2019 Well, I did the capacitor mod, and I can confidently say that it made absolutely no difference. Quote Link to comment Share on other sites More sharing options...
metarog Posted March 24, 2019 Share Posted March 24, 2019 Well it was worth a shot. I looked around but none of my boards have any of those chips. Quote Link to comment Share on other sites More sharing options...
DistantStar001 Posted March 25, 2019 Author Share Posted March 25, 2019 That's alright, thanks for looking. I'll keep poking at it, you never know, I might get lucky. Quote Link to comment Share on other sites More sharing options...
