Problem with Link port
« on: December 05, 2011, 03:33:00 pm »
Hey guys, I have following Problem with my 83+:
For now about 2 weeks or so, errors in xmit occur when I want to receive/send data. At the beginning, the linking worked by performing little pressure on the plug, but now nothing works anymore, I cannot even back up. Since this is a hardware related problem, I should be able to fix this, but I'm not sure If I should do that.
I think its only a contact out of shape in the 2.5 mm jack or a broken solder joint.
Sending the calc to TI isn't a solution, because I need the calc almost everyday at school and I want to keep my data. What shall I do?

- Rewrite/Copy the all my program code since the last backup to another calc by hand and save that on my computer
- Archive everything
- Remove all batteries and unscrew the calc, try to fix the problem by myself
- Buy a new TI, but keep the other for school
(I think this will cause a Ram clear, but the archive should be fine, right?)

If you have all 5 batteries out at the same time you will get a ram clear.

My suggestion would be to archive everything, take the calculator apart, and go from there. Once you get it apart, there's a chance you will see pretty quickly what is wrong, and in that case you can decide what to do.

If you don't know what's wrong, the best way to figure it out would be to plug something into your link port and strip the wire. Then use some kind of circuit tester (multimeter or a battery, some wires, and a light) to figure out where the break is. After you figure that out, then you'll know what to do.


So, I'd try to figure out what's wrong before you buy a new one. But if you do buy a new one, you should get an 84+ and save yourself some disappointment when programs don't work.

OK, thanks. That's what I thought the is the best. And a 84+ would be the right upgrade, but I have to keep my 83+ since this is the only we are allowed to use in exams.

Seriously? 84+ is the same as 83+ as far as exams are concerned.

I also would like to add that there might be an discontinuity in the cable itself.  Make sure to rule that out.

That's strange because only the 84+'s have the Press-to-Test mode.  (uhggh)

Wooho... It works - and no data got lost!
It was just a broken solder connection at one of the contacts, so no big deal - the hardest part was to get the whole thing open, but I managed that.
Thank you guys!
