As the TI-92 Guidebook notes on page 15, "The display may be very dark after you change batteries. "

That diamond key is on the lower left side of the keyboard. You ought to press and hold the diamond key while repeatedly tapping the minus key. It may take 25 presses of the minus key before you see any change on the screen, so don't give up too soon.

Have you tried connecting this monitor to another computer, even a laptop. This would tell you whether the display is bad or the video card is the culprit. I suspect the monitor's power supply is dying. Taking it to a pro for repair should cost @55.00. Buying a new monitor @ $100 - $125.
