Title: My calc mess up horizontal lines
Post by: Yeong on April 14, 2011, 01:23:18 am

I hav TI-84+ SE OS 2.43
It didn't happen before, but it suddenly started to happen.
What is wrong with that? Emulator doesn't have a problem with it.

calc screen:
-----------------------
|Text                       |
|       --------------- |   <--- "Horizontal" line
|                             |
|                             |
|                             |
-----------------------

Check to see which row it is and which hardware model you have. It could be that your display ram is corrupted. but if it is only in the OS you should be fine.

Oh maybe I didn't clarify it well enough.
That horizontal is the Draw command horizontal.
It should draw horizontal line across the whole screen, but some random reason, it won't.

Can those pixels be drawn normally or are they dead?

Have you tried reseting your ram yet. If that doesn't work try resending the OS. I have 2.43 on a 84+ SE too and have never had this problem.

Odd.....I recommend this, testing in between to see if it was fixed:
1: GarbageCollect
2: RAM Clear
3: Full on Reset
4: Remove all batteries, including backup
5: Step 4 for at least 6 hours

Other than that, an OS reinstall might help.

Edit: My post count is now 1337 :P also, OmnomIRC doesn't like it, says I have 0 :P

Is it because you're drawing text over it?  You should draw the text first and then the horizontal line after.  There is a text flag somewhere to tell it if the bottom row of text should overwrite what's under it (or something like that) so its possible that got flagged on your calc.  A ram reset would restore everything though.

I tried resetting a lot but obviously it didn't help.
No, the line doens't overlap with text.
I think it started after installing zstart but i don't think it has to do with anything though.

So your graph screen is offset by a few coordinates, right? I presume that's why the line is messing up.
This has happened to me a few times, I set the Xmin to 0, but the left side of the screen is like -10. I think RAM Clearing could fix this, but I'm not sure...
