HELP My whole system all powers up but NO SOUND

Good morning everyone!!
Last night when i came home,my first thing in my mind is to listen to my system.So,i power up everything and when it's all warmed up ,i start playing my cd and heard nothing.I checked all the fuse and looks all good and no sign of burned fuse?BTW,my system is set up for "BIAMPING ".Tube monoblock driving the upper panel of my speaker (Martin Logan/Aerius) and a solid state amp to power the bottom side ( woofer ).As i said it's all power up but not getting any sound at all in my ML.I did connected another speaker and no sound still.What the heck is happening in my system? Btw,i did even checked the preamp fuse and it looks good and ofcourse i can see it powers up or light's on. I am thinking to open it up last night to check my 12ax7 tubes. is it possible it will be my preamp tubes??
Or the problem will be in the pre-amp??REmember both tube amps and solid state amps power are all ON and lights ON but still not getting any sound.I am at work right now and thinking a lot what really happened? I need all of your input and information so when i reach home hopefully i will enjoy my Friday night.Thank you all very much in advance!

Jameswei,
I have the Jolida JD100.Mute was off all the time and tripled checked the player and the control last night.I turned on my DVD player and having pictures but no sound.Tonight i will check my cd and dvd player in my other system just to make sure.I hope i can find another preamp to check it all.I still suspected it's the preamp?

Are the ML's plugged in, and are their power lights on also?

Is everything else on the circuit working? While highly unlikely could a breaker have switched off or a fuse have blown? Since it seems unlikely everything would have gone have you checked this?

Was anyone else in the room with you? Did they hear the music?

Mcfarland,Yes the ML is always plugged in and i do not have the power lights in my old Aerius ( but biwired).I also connected another speaker and still no sound at all.
Thanks.
Uru975,i am sure everything works.The only equipment works are the tv and directv machine which plugged in to the same surge .As i said everything works still in the room except no sound.Thanks.

Onhwy61,no one except my wife but still no music heard last night.These are all in my bedroom.Thanks.

I just spoke to Jo of Cary Audio in N.C and told what was going on.He told me to check the preamp tubes (6sn7).If the one filament is not working and maybe affecting the other one too,I will try to open and check and replace the tubes if needed.
