Whats up guys!

So Im having an issue with one of my 3000s. When it is powered on, as the subject states, most of the LEDs immediately and perpetually stay lit.

For starters, here's what I have: the screen, buttons and other relevant parts work properly. The LEDs that stay lit are:
Pad Bank
Full Level
16 Levels
Note Variation (After LED)
Play

I have a second 3000 that I have as a backup. I have switched the CPU PCB out with the 3000 in question and the LEDs function as they should. So, I know that the problem is with original CPU PCB.

If you have any troubleshooting advice, please send it my way. Thanks
