Question about Myryad M Series MDP 500 7.1-Channel Amplifier

1 Answer

Pre-amp locks up

After 10 to 20 minutes of operation the pre-amp locks up, usually with a "Myrtad MDP500 Powering-up" message. At tjis point the powerr button does nothing. The only way to get around the problem is to unplug the unit. I suspect a micro-processor problem. Is their a US repair service that anyone knows of? Is a schematic available. I have not received any response from my e-mail communications to Myryad.

    Hallo, I have the same problem whith the MDP500; last year I sent it to the repair center in Milano (Italy), and they kept it for almost three months, saing afther all that it did not showed any problem during their tests, and they sent it back to me. It worked well till one week ago, when the same problem showed up again. I don't know if I should sent it back to the Milano repair center, but it is the only one in Italy. I'm seriously thinking of changing product!

NHT sa-2 amplifier won't go into standby mode after 10 Minutes of no signal

Does the NHT sa-2 have it's own pre-amp? Because I'm wondering if the power off only works when it's own pre-amp is used? So when your receiver is connected it's shut off.

You could try something connected to it's own pre-amp (if it has one) and see if it goes off when there's no signal from that.

L.G CL CODE/ERROR Good Day, Today I will explain to you how to remove the...

L.G CL CODE/ERROR <br /><br />Good Day,<br /><br />Today I will explain to you how to remove the annoying CL code/error on all L.G Dishwashers & Washing Machines.<br /><br />Firstly let me explain let me state that this code is not in fact, an error code. It is actually there to tell you or warn you, that Child Lock has been activated. This feature was added because small children usually fiddle with controls on washing machines & dish washing machines. It is an easy way to lock in an operation and then be assured that it cannot be changed afterwards.<br /><br />The process usually involves you entering a method of washing (like pre-wash, extra dry, quick wash, economy wash etc), then activating child lock - and then have peace of mind that no wandering fingers will tamper with your settings...<br /><br />How to deactivate/activate Child Lock:<br /><br />Here are some examples of various L.G washer Front Panels:<br /><br /><img src="jedemeyer1_23.JPG" /><br /><img src="jedemeyer1_24.JPG" /><br /><img src="jedemeyer1_25.JPG" /><br /><img src="jedemeyer1_26.JPG" /><br /><img src="jedemeyer1_27.JPG" /><br /><img src="jedemeyer1_28.JPG" /><br /><img src="jedemeyer1_29.JPG" /><br /><br /><br />All you need to do is press these two buttons connected via a small child face icon. On certain dishwashers you would need to do this while the door is open.<br /><br /><img src="jedemeyer1_30.jpg" /><br /><br />That's it! All you need to do.<br /><br />I hope this Tip has helped you.<br /><br />Kind Regards<br />JEDEMEYER1<br /><br />* If this Tip helped you in any way, please rate it<br /><br />

I work at a business and have a A T &amp; T Dect 6.0 phone. When I record a message upon playback the message has a tremendous amount of static in it. What do I need to do to rectify the problem

Try resetting the system per the user manual. Usually, this requires powering down the unit for 2-3 minutes. If this doesn't help, hopefully it's still under warranty.

Does it matter at what time I take a pre-workout supplement?

The only time you should avoid taking a pre-workout supplement is late at night because then you will have a hard time falling asleep because of all the stimulants. If you read the labels of different products, it is usually advised not to take a pre-workout supplement four hours before you got to sleep.

Can i hook up a power amp to my denon avr-3300 with out a pre-amp

Yes. Your receiver has the required pre-out connection terminals needed to go to an external amplifier. That would make your receiver operate as the pre-amp/processor.

The door is locked & I cant open it , all the lights fashed & giving error

Please provide us with a make and model so we can give you accurate information.

To address your immediate problem, you will almost certainly find that unplugging from the mains (Not just powering off on the button, as some door locks have a sneak circuit, even when the power is turned off at the button) and leaving the machine undisturbed for a full 20 minutes will allow a reset, the door lock will disengage and all will be well when you power back up.

I have a Tv Philips model 32PW6506/01 few minutes after that is between 10 and 20 minutes go stand by, then if I press p + start and after 10,20 minutes and goes into standby ...If anyone knows about...

Good day!

Usually that problem is cause of the failing capacitors on the power supply section.
You have to do is open the back cover of your TV and look for the actual image of the capacitor with in the power supply section if it is leak/bulged on the top.Please replaced it with the same type,ratings and value.

Thank you and good luck.
