TI-35 Plus I purchased the TI-35 Plus hand-held calculator years ago. I dropped it, the batteries popped out and now it won't turn on. I think it may be the battery contacts. Can it be repaired?

I fixed mine he same way, by cleaning the battery contacts, just this morning, in August of 2020:

I agree - i used a bit of rubbing alcohol on the contacts and bent them inward a slight bit - had to twist the case a bit too but now it works wonderfully and i've had this calculator since it was first out on the market - love it!
