Question about Texas Instruments TI-85 Calculator
I see noone has answered.I needto know something.Were there old batteries left in it for a long amount of time?If there were,they may have leaked and junked it out.Is there any discoloration on the contacts?Also,with an electronic device laying around for so long and not being used,the components within the circuit board may have just lost their value.Capacitors will easily go bad after 15 years of no use.If you ever do not use things for a long time,it needs to be used periodically and have the batteries removed as soon as it is stored.That also applies to A/C being cycled once a month during winter,both house and car,same for heat during summer,perhaps even twice a month.The squiggly lines is most likely an indication of circuitry gone bad.All I can suggest for a last hope is to leave it on for about a half hour in an isolated place in case something leaks.If it is a battery or a capacitor,baking soda will neutralize it and prevent it from corroding further.Greg

Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute
period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
Just keep trying. Sometimes they can be a pain.
