Everett1954 Posted March 16, 2017 Share Posted March 16, 2017 Yes, that is it. You won't find it at Radio Shack. Try DigiKey and Mouser (both mail order) or maybe Console5 (mail order) The grey covering is just heat shrink with the printing on it, if you cut that away (no need to) you would find a metal can. It is soldered in with two leads. Quote Link to comment Share on other sites More sharing options...

Also, are there any other items, other than the caps that I replaced, that I might try? Quote Link to comment Share on other sites More sharing options...

Maybe it is the cart connector like mojo says? Anyone else have something I can try? Quote Link to comment Share on other sites More sharing options...
Hank Rearden Posted March 24, 2017 Author Share Posted March 24, 2017 Although if it was the cart connector, why, without taking out the cartridge, would it sometimes boot up and play just fine and others just give me a high pitched whine and garbled picture. If it loads it plays and doesn't crap out at all. Quote Link to comment Share on other sites More sharing options...
Everett1954 Posted March 24, 2017 Share Posted March 24, 2017 Did not realize your problem was with just two cartridges or I also would have given you a different suggestion? What are the two cartridges? Could be the cart connector or the games themselve Quote Link to comment Share on other sites More sharing options...
Hank Rearden Posted March 25, 2017 Author Share Posted March 25, 2017 Did not realize your problem was with just two cartridges or I also would have given you a different suggestion? What are the two cartridges? Could be the cart connector or the games themselve 2 different Pitfall cartridges and Freeway. All 3 are Activision and play fine on my non-AV units. And in both cases, the Pitfall games have no sound other than when you run into logs. That issue only occurs on my CRT TV. If I hook it up via AV to the LCD, plays fine. But all 3 cartridges have issues just starting up on the AV mod. Most other non-Activision carts never have issues. But when they do run, they play normally unit I shut it all down.

Everett1954 Posted March 25, 2017 Share Posted March 25, 2017 The fact that everything works when you have it hooked up to your LCD TV, makes me think you may have problem with your TV and nothing wrong with 2600. Can you try on another CRT? It iS also possible that you have PAL (Europe and other countries) not NTSC (US) cartridges for those games. Pal carts are programmed for 50Hz TV not 60Hz (us) It would cause problems on a CRT but not a LCD. Provide more info on TV hookup, set etc. if possible.

I take back what I said about playing fine on the LCD. Pitfall only has log sounds no matter where I play it. I just fiddled with several carts and the 3 Activision carts seem to be the worst offenders. They will boot up once in 10 or 12 tries. Once playing it plays fine until I power off the machine. I still don't see how it can be the cartridge slot since I'm only flicking the on and off switch. I'm not reseating cartridge each time. I also tried Mrs Pacman and Superman. They both had issues on startup as well although not as bad as the Activision games. Sometimes I'd just get a blank screen, sometimes vertical colors bars, and others just lines and the high pitched whine. 2 different TeleGames carts seemed to have far fewer issues starting up. And not getting all of the games sounds on Pitfall is very strange. And it does the same thing on both Pitfall carts! Quote Link to comment Share on other sites More sharing options...
SignGuy81 Posted April 20, 2017 Share Posted April 20, 2017 Did you ever get this working? I think you may have the same problem I had here http://atariage.com/forums/topic/264563-no-picture-composite-mod/ Quote Link to comment Share on other sites More sharing options...
Hank Rearden Posted May 7, 2017 Author Share Posted May 7, 2017 Did you ever get this working? I think you may have the same problem I had here http://atariage.com/forums/topic/264563-no-picture-composite-mod/ One of my problems was due to a bad TIA and another problem was due to a bad RIOT? (the middle chip). I still have an issue with that board though as the picture gets distorted on power up but will sometimes correct itself and other times by hitting reset. But it will play fine once it corrects itself. I have more troubleshooting to do on it eventually but I don't have the tools to to go over all the solder joints at this time so I set this board aside for now.

Try replacing C241 and C242 http://www.ebay.com/itm/172288217132?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT Quote Link to comment Share on other sites More sharing options...

So those are all new. Quote Link to comment Share on other sites More sharing options...
