Need to fix HP 12c display



#3

I have an old model of the HP 12-c (says "Made in Malaysia" in the back) and requires (3) 1.5 V batteries.

The bottom half of the numbers in the lcd screen are not displaying properly. They are faded.

I installed 3 new batteries, but this did not solve the problem.

Does anyone know how I can repair this calculator?

Thank you.


#4

with luck you only have some tricky & tiny soldering ahead of you. or you can find one without a case or manual for a song on ebay. the shipping is likely to cost more than your replacement calculator.

since you're a financial person; then you can sell your old battery door for the same price. they are a precious commodity. net loss: 0
