Hi all, first post here. I rescued an abandoned Quadra840av. When you press the power button, the LED turns on, power supply comes up, but no chime.
I went ahead and recapped it with tantalums, found leakage in most electroytics, but not too bad. One trace was corroded and i bridged it accordingly. Still same symptoms: no chime on power on, no video.
Here is what i've done so far:

Here is what i've done so far:
- Checked PSU voltages, seem ok (12V and 5V)
- I am testing it with floppy and scsi disconnected form the motherboard
- I can power on from the keyboard as well not just he power button
- I replaced the battery with a new one - no leakage on the area around it
- I ordered a new SIMM from ebay, maybe it's the memory.
