I have a Macintosh clone PowerWave 604|132. The user's manual is

The power button on the front panel and the button on the keyboard
both cause the fan in the power supply to spin and the LED in the
front to illuminate. The display remains black.

Neither the programmer's interrupt button nor reset button has
effect. Meaning the Apple ROM isn't working? The CPU isn't working?
Should an audible tone come from the speaker when the machine
starts?

One memory card is in each of two banks of sockets. Removing either

The clock battery is probably dead but shouldn't cause this

Adjacent to the memory are ROM and cache SSIMMs in sockets.
Reseating is worth trying but the cards are stuck hard in the sockets.

Other ideas? Poke around with an oscilloscope?

Mac users were never encouraged to fix their own machines.
