The TI-83 Plus is a graphing calculator released in 1999 as an upgrade to the TI-83.

What is this missing component on the logic board?

Opened up my TI-83 Plus calculator (its an older model: 8TA837MB-30B). The board says TI-83 (F) on it. When I opened it, an inductor in the L6 slot was missing. This is located near the I/O jack to connect to the computer. A commercial picture of the board is shown below with where the L6 inductor is supposed to be. I just can’t find out what value of that inductor is so I can replace it. Any help would be much appreciated. I’m doing this more for soldering practice rather than just buy a new board and replace it. Thanks!

@timothydavis288 Hi, missing components aren't always a bad thing, is your calculator functioning properly? If so, I wouldn't worry about it. If it's not working, could you please explain what exactly is going wrong?

I tried plugging it up to the computer and it didn't receive a program I sent to it. I assumed that was the problem. It worked fine on another model. Opening it up showed that there was a missing component and so I deduced that that was the culprit.

Does it run fine? If so, I wouldn’t worry about the inductor. But, if you’re doing soldering practice, it’s probably best to use a completely broken board (e.g fried motherboard from a desktop, vcr mainboard, etc)

Good luck!

That does help! But no, it does not recieve programs from the computer. So I deduce that the inductor is the problem.
