Texas Instruments TI-30 XS Multiview Troubleshooting
The TI-30XS is a scientific calculator made by Texas Instruments. It can perform trigonometric functions, store up to seven variables, and has three viewing modes.
- The TI-30 XS won't turn on
- The screen turns on, but quickly turns back off
- The battery life is really short
- The buttons are sticky
No matter what you do, you can't get the calculator to turn on.
If the calculator appears to be dead, there may be an easy fix. Before physically opening the device, make sure to check the contrast settings. The contrast may be set to zero or very low, giving the impression of a dead battery.
If the TI-30 XS won't turn on outside in direct sunlight, the battery has most likely gone dead. Unfortunately, there is no way to charge the TI-30 XS, so the battery needs to be replaced.
If you have ruled out other options and the calculator still will not turn on, it is possible that the display has gone bad. The screen will need to be switched out for a new one.
Shortly after turning the calculator on, the screen will turn off.
If the screen flashes on and then off, it is still getting power, just not enough. This problem may be due to bad wiring. If faulty wiring is the case, then the ribbon connection from the screen to the battery will have to be re-wired and re-soldered. This connection can be accessed after taking off the back panel of the calculator.
The battery may be low if the screen turns on, but immediately turns off. If this is the case, the battery will have to be replaced.
Even when a new battery is put in the calculator, it seems to drain faster then usual.
If you replaced the battery and it dies quickly, the solar panel used to charge the battery is most likely no longer working. Check to make sure there is nothing covering the front panel at the top preventing light from entering. If the solar panel is unobstructed, it will need to be replaced.
The buttons won't bounce back quickly, or they don't bounce back up at all.
The buttons not bouncing up is most likely due to the presence of dirt or other items blocking the space the buttons move through. Try clearing the space by blowing compressed air on the keyboard.
