I searching for TI-83 calculator schematics, but nothing found.
The issue: When I insert batteries into calculator and power it on....OK! But when auto power off or 2nd/off pressed the screen contents disappear and the screen remain light grey. Current consumption is 20mA when power is off and 30mA when power is on.
If power is on then all function is OK and selftest OK.
Thank You!
