Same result after washing :-(

No start chime, no floppy spinning.

But now I have seen on the backside, there are three red SMD glue points without resistiors on R218 - R220. Nearly the CPU socket pins.

The solder points are looking normal. Nearly no solder. So the resistor are not torn off.

Is there anywhere a BOM (bill of materials) or a repair guide of the Quadra?

Thanks for all the input
