I have and old ti-92 that worked fine, have not started it in a few years. I decided to put some new batteries in it and nothing. Screen seems blueish. I changed the cmos battery (tested 2.8 should been ok) and that did not help. Sure I lost my OS. Have not really dug for service manuals, wondering if anyone has had any similar issues or knows sources..
Out of all my old calculators, this one decided not to turn back on
The screen does turn more blueish when you turn it on, but nothing is present. Just dark blue screen. The brightness levels do nothing.
