Re: Scrambled images on screen!!!
I think you may have an app that is interfering and running when it shouldn't. I'd try deleting or reset the calculator. When you put things back on don't do everything at once. A little at a time until you find out which is giving you problems. email@example.com

From the RAM ARCHIVE ALL menu, select 1:ALL RAM to display the RESET RAM menu or 2:Defaults to display the RESET DEFAULTS menu. 2. If you are resetting RAM, read the message below the RESET RAM menu. • To cancel the reset and return to the home screen, press . • To erase RAM memory or reset defaults, select 2:Reset. Depending on your choice, the message RAM cleared or Defaults set is displayed on the home screen.

TI calculators have an annoying habit of dimming the screen when the batteries are changed so that it appears as if the calculator isn't turning on at all. Turn the calculator on (or at least press the ON key). Press and release the 2ND key. Press and hold the Up-arrow key for a few seconds and see whether the screen becomes legible.
yamaha dx100 reset. Press voice switches 1 and 2 while turning power switch on. Display will say test entry?. press the plus/yes button. This will reinitialize all memory to factory settings. Also the lithium ram backup battery voltage will be displayed as check level with a number representing the battery voltage. The number will be 10 times the actual battery voltage. A new battery will display 33 representing 3.3 volts. If your reading is below 22 then your battery is shot and will need replacing and if you turn the unit off it will probably get a scrambled memory again.
