Scott and others,
I had tried several resets and 990 could only turn on a few times after each reset.
I noticed that the turn on sequency response is rather slow. In the past, once I pressed the "DVD" OR "CD" button on the remote, the 990 kicked in (turned on) instantly, with two distinctive "click" "click" sounds. (i.e. "click" "click" at once). But not now. After the first "Click" sound, the 5 speaker icons showed up on the front panel window, without the words next to them. After about 1 second and half, 2nd "Click" was heard, then the words next the the speaker icon appeared. Again, the double clicks would be heard almost instantly in the past, but not now.
If I heard clearly the double clicks instantly and distinctively after the pressed the POWER button on the remote, I can turn back the 990 on, after the remote's light were gone.
990 could not turn back on if I only heard 1 weak "click" after pressing the POWER button.
Awaiting more direction from Scott. Pls tell me if I have to call you on the phone. If yes, pls give me your phone number and the time to call you. I am at New Jersey, East Coast. Tks.
Kwok Lau.
