Question about Texas Instruments TI-86 Calculator
My son in school was pushing on the screen and now there are big marks there how can i get rid of this.
If they are smudges, or smear marks, clean them with a soft cloth with some isopropyl alcohol (rubbing alcohol, very little). If LCD screen is damaged I do not know what you can do except having it repaired.
Hope it helps.
