The c7 capacitor on the the pcb seems to be damaged.
I took apart my TI-83 plus to see what was wrong with it, and I found out that the c7 capacitor does not work properly. Does anyone know what the c7 capacitor is so I can replace it?

According to this site, the capacitor is suppose to be 27pf.
What exactly is wrong with your calculator? It may not be a hardware problem and I can help you if it’s a software issue.

I actually fount a similar website for finding the PCB layout, but the websites seem to be different. are you sure the site is a ti-83 plus and not a ti-83?
@cue Dang you're right, looks like that's a plain old TI-83. Good catch, unfortunately I'm not sure if I can find the value on a TI-83 Plus. I'll see what I can do though.
