Black Screen

[JesusFreak]

so here goes, my friends calc. won't work, when we can get it to turn on, the screne is black, and twice we got is to show text, but it froze. Also she had a piece of plastic in the port. I tried to redo the the OS, but it didn't work.

what should i do??? (is the tape all used up?

[X1011]

Try taking the batteries out (including the little one) and hold clear+on while you put them back in.

[Adm.Wiggin]

that is evil

i noticed you said 'she' :lol:

hmm... i would try what X1011 said, and if that doesnt work, hit it with a hammer (jk on this one )

That's some pretty odd behavior for a calc. I'd start by removing all the batteries; including the backup cell. If that doesn't work I'd remove the batteries again and short the +/- battery terminals with a stick of graphite (from a mechanical pencil). This should reset any residual data in the static RAM. If that doesn't work, it's time to visit eBay.

[Darth Android]

if you can, use a piece of wire instead of graphite...graphite has a high resistance

[DigiTan]

Precisely, using graphite will ensure a slower and longer capacitance discharge away from any devices that may be holding the residual charge. Otherwise, you'd run the risk of exceeding the max allowable current for those devices in the discharging "pulse".

Did you check the contrast?

I'm all up for the hammer idea.

[JesusFreak]

i'm not dumb, i took the bateries out, that is a given, and yes i did try the contrast, i even too a calc. picture on my comp. and it just showed a bunch of lines and stuff.

i will try the graphite, and on + whatever

[Newbie]

y the sound of it she will probally have to buy a new one if the graphite does not work.

It forces the Flash memory to run a self check, in which it turns each individual bit on, reads to ensure that it turned on, and then turns them all off, and reads to make sure they're all off. extremely destructive to anything stored anywhere on the calc, since you'll need to re-install the os, thus clearing the ram, and it clears the arc itself. But it's good for solving problems caused by anything bad being on the calc.

[DigiTan]

Oh, I forgot to ask earlier: was the calc damaged somehow? (Left out in the snow, etc.?)

[62 52 53 53]

and DON'T take the batts out when you do on+clear

[Awesome1]

this ain't gunna help...i was walking home from my bus stop (at the time lived in a trailerpark), my calc fell outa my bookbag and into the snow somewhere. I spent about a week or two looking for it. I got it back froma friend who found it. LUCKY ME!!!. The screws were all rusted so i took it apart with a torx wrench and dried it off. It was soaked in the inside. It was hairy for a while, didn't do add subtract, divide and other stuff right for a couple days. After some use it straitend right out. Works perfect now.

So i don't think the snow would harm it. Maybe if u submerged it in water.

But that is a problem i have not heard of. Try e-mailing the people at ti or something. Or tell "her" that she's gotta spend $90-$100 on a new calc.

*In an evil look*
What does taking the batteries out doing the self-test do???

[Toksyuryel]

I would imagine the same thing as if an ERR:BREAK were to somehow occur durring a garbageCollect: total destruction of the ROM.

[Fr0sty]

Call TI, they sent me a silver edition and I haven't even mailed mine back yet. I've had it for like 5 months
