Hi guys,

I turned on my cx cas H model today and when I tried to calculate certain things, I found that they wouldn't become visible on the calculator.

My middle panel of buttons (the ones where the numbers are and other buttons incl delete are located) don't work. But my the top and bottom panels work (I can still turn on the calculator and get pronumerals and things like that)

Is there anyway I can fix this without having to buy extra parts.

Hope you guys can help
