Why do I have blank lines going across my screen?
Everytime I try to use my calculator I cannot read it because there are blank lines across my screen. Is there anyway I can fix this?
It sounds like your ribbon cable is failing or become loose. This is a common issue and not incredibly difficult to fix. You can find a great guide for it here.
这个答案有帮助吗?
I appreciate but i doubt the people with these calculators have that many wires to waste, none the less the soldering skills to do that.
