Well, I don't have a link cable, so I can't resend the OS. It worked Today, but I am afraid it may crash again. And yes, I did check the contrast. I think the batteries in it are new, but I don't have any backup batteries for it Since it is working for today, my main concern is learning what caused the problem. I have an ASM program on there to check the batteries, and it says they are low, so I will probably need new ones soon. I opened up the calc and used a meter to check all the LCD connections, and they seemed fine. Could low temperature cause an internal failure? It also was working a few days ago, after a few dozen hard resets. It started working today when I did a hard reset, and the message wasn't conjumbled. I pressed on to exit the reinstall OS thing, and when I turned it on, I t worked fine. I really, REALLY want to know why this sort of thing happens so I can prevent it in the future, and help others with their calc problems.

That line right there says to me that it was just a simple crash or something. In any case, here are a few things you can do:

1. Press Mode -> Alpha -> S (ln). And then press enter a few times and wait for the 0 to turn to a 1. If it does indeed turn into a one, then your OS is fine. If it say ROM FAIL, then your OS is corrupt and you'll have to work on resending it. (It's unlikely that it's corrupt).

2. Wait it out for now. See if the problem comes back. If it does, I would assume the "battery + DEL" combo will fix it

3. If it comes back, do "battery + DEL" and then clear all of your memory (2nd -> + -> 7 -> left -> 1 -> 2). Though, before you do this, I recommend you go find a link cable and send your stuff to your computer.

4. If after all 4 of these, you still encounter the glitch, then we can indeed call it a hardware problem. But until then, I'm going to guess it's just a crash.
