How can I re-align the screen on a TI-85?

I obtained a secondhand TI-85 for a dollar today. It didn't power on, so I removed all the batteries and put a jumper across the contacts for the memory backup, which cleared the memory and reset everything to default. HOWEVER,

The LCD seems to be calibrated 4 pixels off. When anything is entered into the base screen, the left four pixels are off the display, leaving the fifth column of the character to be nudged up against the left side of the display. When I graph something, however, the display is centered. Any ideas what could be causing this? A second "Reset All" didn't help. I'm a TI-83 user, so I'm not familiar with the TI-85 interface.

Are you sure the physical screen hasn't been shifted during a fall or otherwise? (sloppy repair for instance)

 I would try taking out the CMOS battery for a few minutes. If you open the battery, there's the AA's, and a little screw holding down a small piece of plastic, take out the screw and remove the battery, theoretically clearing all the memory. Just a suggestion, no guarantees :P

Already did that. Thanks for the suggestion, though.

 Ohhhhhh my bad, I thought that you were talking about the AA's. Never mind then :P

Here's a link to the manual if you don't have one.  It won't solve your problem but it might come in handy sometime.

You reset the memory backup.  Did you try doing this several times.  It may be that it just didn't come up right the first time.

You might try joining a calculator forum.  I'll bet they could get you the answer you need right away.  Like this one.

Nice calculator for a buck if you can get the screen adjusted and there is probably a way to set that if you can find the service code.
