Question about Texas Instruments TI-89 Calculator
Battery in my TI 89 leaked and now the calculator doesn't do anything. ie. it is just blank or just some black stripes on the LCD. Is there a way to get my calculator fixed.
Try doing a hard reset (hold simultaneously Left + Right + 2nd + On). If it just isn't wanting to display properly, but does turn on, that might help. I think you can do the same thing by taking the four AAA's out and the spare CR1616/CR1620. Otherwise, the battery acid probably ate one of your components and it's time to repair/replace your handy-dandy.
