Sharp VC 584UB clock lights up but won't power on

Does it power on with the remote? Some front panel circuit boards have all buttons going to a single analog line on a control IC and each button pulls down or up through a different value of resistor that the chip senses. If a resistor drifts enough the IC no longer interprets the button it connects to as the function it's supposed to be.

I didn't get the remote with it but from looking online the original remote doesn't have a power button.
I also noticed the CH buttons don't work either when setting the timer it just says on CH 2

That is a very good point! Also when the tactile buttons get oxidized, resistance goes high and the control IC misinterprets what button is being pressed. Sometimes if you keep working the buttons, they start making better contact. It's worth a try.
