Sharp ZQ-5650 older pocket organizer. Repair question.
Hi folks, thanks for reading. So I have the said pocket organizer that needs a battery change. Every time I change the battery's on something like this, it mess's up the display big time. Dead pixels. To where it's no longer functioning and I have to throw it out. Is there any way to avoid this? This model actually has a little button on the back but that could be for the door. I'd really appreciate it any help. Hopefully it doesn't require anything more then a multimeter, I do have one of those but that's about it. This model takes a 2032 and 2 x AAA's.
I really do not want to screw this up. Thanks.
And Im a real person not a bot!!!
