Harmon Kardon hk870, 825 help please


I have aquired some 80's Harmon Kardon equipment and can't seem to get anything to make noise.
When the hk825 preamp is turned on the indicator lights flash.I wonder if this is an indicator of a fault?
I have two hk 870 amps and on both the "wait and power" indicator lights do not come on but I do know the amps are drawing current.
I have hooked a working tuner to the preamp and no noise.
I can't believe the whole thing is toast.I got it from an estate sale and everything was well packed and looks like it was well cared for .
Any help appreciated.

Hopefully someone can properly interpret the flashing indicator lights.

If not, try outputing the preamp into a known working amp. If you can get a radio station to play out your speakers this way, the HK 870s should go to a repair shop.

Otherwise, try inputing a known working preamp into the HK 870s to see if they are the problem.
