Question about Lexicon MC-8 8-Channel Amplifier

Open Question

I have an MC-8 that is freezing up, it started with the Satelite, losing sound, muting and locking up, I would have to un plug it and reset it, then it would work for a short time, but eventually got worse,now it wont produce sound at all through satelite. Just today now, I tried to adjust the speaker levels and it wont produce sound through the speakers, whatever it is its getting worse, I can listen to movies ok, that is all that works, thx jay Email James67gang@aol.com

How do i un lock my sound


Check for the Mute function if the sound is off.
Still if it does not work, take out the batteries and mains power and re install and start again as the system will reboot.

If I hit the reset button on my mp3 player to un-freeze it, will I lose my current music on it?


Hi Stacey,
Using the reset button of an mp3 player will not cause loss of music or other media files.
I hope you can un-freeze it in this way but in my opinion the problem could be solved in few cases.
Thanks.

I have been watching my LG 42LD520 for 2 months. Today turned it on and there is no sound. Any ideas??


If you are using a satelite system...just unplug the satelite receiver for 30 seconds and plug back up. Try unpluging the TV and check for the mute function...it may be off. Also go to the sound menu in the TV and be sure the speakers are on. The worst problem is a main signal board.

I have a Kenwood KDC 135 car stereo wont un mute.


behind the face plate there is a little recessed reset button. push it using the tip of a pen or similar. that will fully reset the radio to like it was when you bought it.

Some times head units hicup. this is how you reset it. In most error cases this solves the problem.

Toshiba satelite isn't recognizing that the


Have you tried using a different mic? If its a cheap mic It may have very well just quit working(or never worked).
Is it a new laptop? If not, any previous issues/problems?

"Apparently" the drivers are updated? "Apparently" isn't exactly a good term to use when it comes to something like drivers. Its either: Yes, they are or No, they are not. Make sure they are first.

To test if the mic is/isn't working go to Control Panel> Sounds and Audio Devices>Advanced Button(Bring up the Mixer)>Properties>Make sure Mic is checked in the list. Go back to the mixer, and un-mute the mic and slide the volume bar all the way if it isn't already. Now talk into the mic, is it playing threw the speakers? Yes? No?

From what you've provided I would guess its just a bad/broke mic. I'd suggest investing in something better, like a headset with the mic built in(as you'll probably need one at some point anyways).

No audio How to un mute


Hello

I'm using the same laptop right now and have been for 3 years and I didn't know there was a key combo. Can you go into Start, Control Panel, Sounds and Audio Devices? If you can then you can unmute there.

Picture and sound problem


If your getting your signal via a satelite receiver or HD cable box, its likely that the sound dropouts and picture freeze are the result of marginal signal strength. Does the TV ever do this when using a DVD player? If not, its certainly the quality of the signal.

If the TV is at fault, the problem will be on the digital board.

No volume on my F20


It sounds like you have muted your F20.
If this is the case you need to turn on the Sat Nav (outside so it picks up the Sats). Once the sats have loaded and machine is working. Press the arrow button bottom right, which takes you to map pages, press the screen on an empty area on the map page. This will bring up another on screen menu which gives you another 6 options (these include pausing routes, brightness etc..) one of the options is 'mute' (top right on screen button) press the button once and you should be un-muted.(It is one press to mute and press again to un-mute). Once un-muted, use the side + & - keys to raise and lower volume.
Hope this helps, if you are already un-muted and still have no volume, you may have a faulty unit. You could try a master reset by inserting a pin into the reset hole on the bottom of the unit.
