If you hold down a button for say 5 seconds, does the calculator finally do what you want it to?

If so, try resetting the calculator's memory
2nd+MEM+7+(left)+1+2
that should reset your calculator.

If not, try blowing really hard into the I/O port... that usually helps

MINTEK TV - Black screen in the center of the picture


This is the closed captioning text box. Search the menus to turn off closed captioning. The reason for its seemingly random appearance is that not all channels nor all programs provide this service.

JVC picture turns into a single line in middle of screen.


This is caused due to random falure of vertical scan circuits. It generally is caused by dried out capacitors or bad driver IC. Unfortunately it will get worse. If you fail to turn the TV off quickly you will burn a permenant horizontal line on the tube. Trip to the repair shop I am afraid.

Blackberry Curve that turns off randomly


Try using a different battery. Possibility is battery may be depleting fast when you turn the phone on. If phone works with the new battery that means your battery needs to be replaced.

Battery problems


Your battery is defective, needs to be replaced.
Batteries need to be charged in a random pattern and need to be worn down randomly,else they develop a memory and won't fully charge.

You have a bad vertical deflection IC and/or bad capacitors in the vertical circuit. The parts are inexpensive and can easily be replace by a service technitian.
