CrazyBoss Posted April 18, 2016 Share Posted April 18, 2016 Hi. I wanted to show my son (age and wife about early Computer game history, and took my Pong Gamatic 7600 from the Basement, and start to connect it to the tv, my wife said it smells like burning, and she was right - Last time I used the game was 15+ year ago, and it worked great. It seems like a big resistor is burned out. I cant see what value it have. The caps looks good but again they might be out of specs. since the game is from the 70's i guess. Previous I have repaired a Humax Satelite box (PSU), cause the resistor also burned, in that case you had to change a CAP, a Z Diod and the burned out Resistor. Wonder if its the same here, I see a cap and a Z Diod near the burnedout resistor. Quote Link to comment Share on other sites More sharing options...

Wonder if its the same here, I see a cap and a Z Diod near the burnedout resistor. Pictures would be a great help in identifying the issue. It's also unlikely that a resistor burned out (maybe it's something you're confusing for a resistor?). If a resistor blew - it's likely that the whole system went as well. Also - how can you see that a diode is burned out? Did you test it with a multimeter? I'm also curious how you can tell it's a Zener Diode just by looking at it... Anyways, yeah we need some pictures or else no one can really help you... Quote Link to comment Share on other sites More sharing options...
CrazyBoss Posted April 18, 2016 Author Share Posted April 18, 2016 i will get back with pictures later I hope I can repair it, since I really want to tell me son what PONG is Quote Link to comment Share on other sites More sharing options...

Jan1980 Posted November 5, 2020 Share Posted November 5, 2020 I had the same problem today... The problem is, there is written 9V AC on the plug. But you need 9V DC !!! The sticker is not correctly !! Jan Quote Link to comment Share on other sites More sharing options...
afronob Posted April 22, 2021 Share Posted April 22, 2021 Hi, I've got the exact same problem with mine. Did you finally find the resistor who is needed a this place ? Have you got a reference to share ? Thanks :) Quote Link to comment Share on other sites More sharing options...
afronob Posted May 19, 2021 Share Posted May 19, 2021 I found the resistor you looking for : 10 Ω ± 5% Quote Link to comment Share on other sites More sharing options...
