Question about Texas Instruments TI-30XA Calculator
I think the display on my calculator is broken b/c when I turn it on it says 7 rather than 0. as I punch in numbers 1-9 acroos the screen they become more clear and legible. could it be the ribbon cable from the circuitboard to the display? is it even worth wasting time over? I believe I can buy a new one for about $15 so it may be more trouble than its worth.
Either battery is dying, or circuit board has gone, or connector cable loose.
You can replace battery by removing 6 screws at back of calculator, but cost of battery is around 40% of buying new TI-30XA for $10 from Amazon, Staples or elsewhere.
I've used TI-30XA's for years, batteries usually last 2-3 years, then I buy new calculator. The one time I tried to replace battery, fading display still problem, so circuit board had gone bad.
So you could try battery replace and may be OK, but also may be waste of time and $$
