GE profile advantium 120 PSBSB1201NSS01 no display, won’t operate

I have a GE profile advantium 120 PSBSB1201NSS01 microwave from 2009. Display is out, no oven operation but the turntable runs when the door is closed. The display and operation worked a few times when closing the door and flickered when I was checking the door switches. I figured it must be bad switch so I replaced them but still no display or operation. But the turntable still runs when closed. Pushing the touchpad I can hear faint clicks. Any ideas?
