dphirschler Posted August 6, 2014 Share Posted August 6, 2014 I have an Extended Basic cartridge that is non-functional. It won't even boot to the TI title screen when the cart is plugged in. I am considering repairing it, but first I have some questions for the experts out there.1. Is it worth it to try to repair it?2. Where can I find some resources on troubleshooting/repairing these carts (and specifically this one). Darryl Quote Link to comment Share on other sites More sharing options...
+arcadeshopper Posted August 6, 2014 Share Posted August 6, 2014 (edited) I have an Extended Basic cartridge that is non-functional. It won't even boot to the TI title screen when the cart is plugged in. I am considering repairing it, but first I have some questions for the experts out there. 1. Is it worth it to try to repair it? 2. Where can I find some resources on troubleshooting/repairing these carts (and specifically this one). Darryl Carts are tough.. if its not working it's either a short, break or the grom or rom is damaged. They are pretty simple boards.. Imho if its not an obvious short or broken trace its dead. If you want to try and end up failing to repair it, I'll send you a working one if you mail it to me. I can recycle the case into something new. I have a few spares and with UBERgrom boards the originals are pretty much extras now.. Greg Edited August 6, 2014 by arcadeshopper Quote Link to comment Share on other sites More sharing options...
ti99iuc Posted August 6, 2014 Share Posted August 6, 2014 I had some problems with cartridges among my collection, and I must say that I learned to make several attempts before giving up for dead a cartridge. try to: - open the cartridge case and clean the contacts, sometime, dirty contacts could be a problem for a good working; - try to insert the PCB without plastic case and see if it work, it's happened that some of my cartridges work without case and in the case have problem, i do not never understand why. - check the bottom of the cartridge, if the welds are all ok or there is some imprecision, skip welds or damaged or oxidized; if, after all this check all seems to be ok, well ... the probability that the cartridge is dead is high...

am1933 Posted August 6, 2014 Share Posted August 6, 2014 Sometimes they are not dead and are simply pining for the fjords If all the above checks have been tried I,m afraid- Your cartridge is no more, it's expired and gone to meet it's maker,it's a stiff, bereft of life, it rests in peace, it's metabolic processes are now history, it's off the twig, it's kicked the bucket, it's shuffled off it's mortal coil-run down the curtain and joined the choir invisible. IT IS AN EX CARTRIDGE!!!! 2 Quote Link to comment Share on other sites More sharing options...

Agreed dirty contacts AND dirty cartridge port can be the issue as well.. If your console is old and well used the port usually gets too dirty to function, and the felt "cleaner" gets gunked into the socket.. http://www.mainbyte.com/ti99/console/console_dis.html the cartridge extender is a little board.. with a socket.. easy to remove and clean and remove the felt from if it's a mess Greg Quote Link to comment Share on other sites More sharing options...
dphirschler Posted August 7, 2014 Author Share Posted August 7, 2014 Well, I have tried all the suggestions above except for examining the contacts on the bottom of the board. Is there a guide that can tell me where to probe and what values I should be getting? Can you tell I am a novice at troublehooting electronic hardware? @Greg, you'll seriously send me a working one in trade for my bad one? That's very generous of you. It's starting to look like I might need to take your offer. But I am not quite ready to give up on it yet. But admittedly, it is looking bleak. :-( Darryl Quote Link to comment Share on other sites More sharing options...
