My speakers just stopped working. No power when I turn know to turn on and increase volume


Ir you are lucky it will be your power supply that's gone dead. Use a volt meter to see if the power supply is working or try to find a power supply with the same characteristics (voltage, polarity and amperage). If that doesn't work, the amplifier may be busted. If so you'll need new speakers.

My dc691p speakers require 9 vold dc. Will it do any harm to use a 19 volt dc


yes, your speakers will be damaged. do not connect 19 volts to a 9 volt device. go to walmart or radioshack and purchase the correct power supply.

No power to my computer can mother board be out


The 2400 C is listed as a desktop model--I would suggest the power supply in the unit may be bad--seen some reports on the internet about this.

Some of these units (and other equipment as well) have issues with the power supply:

Every set has a standby power supplythat is running 7/24 if the set is plugged in and it supplies voltage to theremote circuit that turn on the main power supply for the tv and hence turn theset on.

This is an area where companies cut corners by using lower rated voltage caps.By this I mean Standby usually provides under 10 volts to trigger the seton----what they do is use filter caps rated at say 10 volts max in a circuitwith 9 volts (example)=with the standby on all the time the filter caps(electrolytic caps) dry out and fail.

The problem usually begins where you have to turn set on or or two times andgradually gets worse--takes longer and more tries to get it to come up.

Once on it will stay on until turned off for a period of time.

The caps will begin to work better (regain some of thecapacitance) as they get hot--hence one it is on it will seem ok.

The beauty of this problem is most of themhappen when set is a year or two old (no warranty) and all you have to do islook at the top to locate bad ones.

They are generally black or blue and round and vary in --they have twoconnections each--a + for positive and a - for negative--not unlike a batterywhich in a way they are. The + and - are marked on top and bottom of most boards.

They are easy to replace and not expensive parts.

The tops are silverand metal looking with creases on top and if bad they will be puffed up ontop---tops must be perfectly flat with no brown material leaking top or bottom.

If this is your problem once you id them (make a drawing) you can begin.

Here is the critical part---on each cap is also marked the value like 220uf 10vdc---220 micro farad at 10 volts maximum.

If you find for example 6 puffed up and all are 10 vdc replace them with thesame value capacitance (like the 220 uf) but go up to at least in this case(from 10 volts) to a 16 or higher rated voltage cap.

The only issue is when you go up in voltage rated value the cap is larger sosometimes there is an issue of physical space for the replacement on the boardto fit them in.

The reason they cheapen these sets in this way is if 10 caps and you make25,000 sets there is a considerable savings in parts cost.

They do not care as long as it lasts past the usual one year parts warranty.

I have taken the time to be long winded because this really sounds like it maybe the problem you have.

See attached photo of a typical cap and if you have questions or need advicelet me know.

In your case if you get inside and see damaged parts like these you can either have them replaced or buy a replacement power supply for the unit.

Hello everyone! I have lost my Koss HD50 power supply and was wondering again, how many volts and how many amps? ex:6V, 500ma Thank you kindly! Erjel


Three C cell size batteries per speaker is what you use if you are on the go.

http://www.shopping.com/Koss-HD-50/the-paradox-decent-small-computer-speakers/1386310/reviews#tabAnchor

Hmmm.

EACH C cell battery produces 1.5 Volts (DC)
3 times 1.5 Volts (DC) = 4.5 Volts
Total of 9 Volts (DC)

500 MilliAmps?

Your main concern is with the Voltage.
The Amperage can vary. It can be more than needed.
Why?

Because Amperage represents Current.
How much Current is available.

(Water hose example;
Voltage is the speed, or velocity of the water coming out. Amperage is how many gallons per minute that comes out of the hose)

However, you better make sure that EACH speaker receives No more than 4.5 Volts (DC)
Since you do not have the special splitter adapter cord that comes with the power brick, you will have ensure that EACH speaker receives no more than 4.5 volts.

This is if you are trying to use a 9 Volt (DC) power supply. (AC adapter)

I plugged power supply into 220 volt. do you


check out for the main fuse in system, and if you have 110v, rating..then the transfomer for the device is damaged, just replace the transfomer and on the system again..the whole system is not damaged, could be the transfomer, and the fuse.

Incorrect voltage input


Check the fuse. Otherwise there's another fuse at the low voltage transformer itself. it will be covered with plastic tape on the primary winding of the transformer. Just replace it and enjoy your music

Good luck
