Thank you gonk!

Guys, You know what, I got back my 990 last week and still got the problem of not getting it powered on.
I called Scott and he advised me to plug the 990 directly to the wall outlet. (I have been hooking up the 990 and other gears with 3 x ISOBAR Power/line conditioners at 3 different wall outlets.).
I plugged the 990 directly to a wall outlet last night. It could be turned on by the remove. I tried this morning again and it turned on. I will try again this evening to see what will happen.
Scott would be right, that the ISO Bar power conditioner is good for PCs, not for HiFi gears.
I would share this experience with you guys.

Scott, thanks.
