Re: TI83+ graphing calculator

kc8adu- I checked the fuse, there's continuity on both.
Diggie- I cleaned them both with rubbing alcohol (90%)
bluto- I didn't try and mods but I would be willing to change out the resistors and capacitors. I'd greatly appreciate if anyone could help me identify them - with the SMD devices I am really lost.
mockingbird- That's really interesting. I didn't come across that video in my google research. I tried testing the resistance and it doesn't appear to be my problem. Great advice though!
CMJ21973 - I tried all the steps on...

Re: TI83+ graphing calculator

Severach: I can't cheat. She want's to watch me fix them.

Shovelnose: She says she never dropped hers and I know for a fact that mine was well taken care of and never had any issues with liquids or drops. As for mine, one day it just wouldn't turn on any more. She claims the same happened to hers with the black screen.

Iti: I'm more than willing to host the pictures any place you feel safe. I use imagebam a lot because it doesn't require an account and holds a fairly large size image. I wanted to be sure to preserve the detail....

Re: TI83+ graphing calculator

Yes. I checked this and did the hardware reset key sequences. Unfortunately it didn't do the trick. Good advice nonetheless.

Re: TI83+ graphing calculator

Wow, I'm an idiot. When powered on, one does not respond/turn on at all and the other has a completely black screen (as if all pixels are turned on.)

Is there anything else I can tell you?

My girlfriend and I each have a broken TI83+ graphing calculator. One night I boasted that I bet I could fix both of them; she laughed and said that she didn't think so. Anyways, long story short: we have a very lucrative bet going on now. This is not about money, or if it is "worth it" to fix these. I NEED to win this bet (if you get my drift.) I've got good soldering skills so that won't be an issue. I need advice where to start. I'm fairly lost with these surface mount devices.
