K8098 Audio Analyzer blank screen

Kits Audio Hi Fi Projects

I just purchased a K8098 audio analyzer from Jameco in USA.
Symptom is no display except for backlight.
I have checked all component values, and checked signals with an oscilloscope. VDD is 3.28V. No signals on any pins, except for pin 10, Crystal. This signal varies from about 22MHz to 42MHz, which seems way too high for the MCU and specified crystal. I understand that the PIC is supposed to work without a crystal. but it looks like either the MCU needs a crystal or is dead and needs replacing.
Please advise on any changes to be made, or other actions i can take, including getting a replacement MCU.
