I need a compatible low-cost power supply for this monitor, MAG LT565 but I have no idea what size DC plug will fit it . Any one?

eMachines are a budget computer.

Designed to save the consumer money.
One of the items used that cost is saved on, is the Power Supply.

Power Supply is generic, and of low quality.
1) Low quality Electrolytic Capacitors
2) Low quality Power MOSFETs
3) Low quality Rectifier Bridge
4) Too small a gauge of wiring is used

Plus most consumers do not keep the inside of the computer clean, and if they do the Power Supply is usually neglected.
The two leading causes of desktop computer failure; the computer is dirty inside, and/or the Power Supply is bad.

With a weak voltage power rail you may see LED's light, and maybe fans spin, but there won't be enough power to turn the Processor on.

[No Processor operating, no computer. No computer = no video signal to the monitor. No Signal, Power Saver Mode, or Sleep Mode is indicated ]

1) If ALL of the LED's were lit up they would use less than 1 Watt of power.

2) EACH fan uses 2 to 3 Watts of power.

3) A typical Processor can use from 51 to 125 Watts of power.
Just depends on what Processor it is.

See if there is an unused working computer that has a KNOWN to be good, Compatible power supply; that you can use for a test unit.

Or use a multimeter to test the three main voltages, coming out of the Power Supply
3.3 Volts (DC) [ Orange wires ]
5 Volts (DC) [ Red wires ]
12 Volts (DC) [ Yellow wires ]
[ALL Black wires are Ground wires ]

For additional questions please post in a Comment.

Go to www.partstore.com for a new power supply.

The power cord is a standard PC style cord ...

Try maplins i got one the other days for £24.99 they have a sale on at the moment, thats if you are in the UK of course...switching mode power supply model no. L11BQ, flung the box so can do any better than that im afraid

Hi,

Your description is the external power supply/adapter for a Mag Innovision LT776s 17 in. Flat Panel LCD Monitor. One may be purchased here. Aftermarket/replacements may be found here, here or here. Pls verify that the plug matches the jack and the polarity is correct. Additionally, if it would be a replacement, pls check the voltage and current rating.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

The order the plug wires go is from the top right side - pink /blue

The bottom side - blue /pink

Your question was presumably cut off in the title of your post, but on the power brick, there should be several statistics of the power supplied by the cable. There should be watts, Amps, and whether the output is AC or DC. I believe your monitor takes DC power, so if you are buying another power supply, make sure that it gives out DC power, not AC. Also make sure to get the specific wattage, and for a monitor that size, 3.0 amps should be more than enough to keep a steady power flow, and also keep the power brick at a reasonable temperature.

The correct one would be 12v @ 2.5 to 3 Amp.
If the set used less current than 1 amp it would be in milliamp (500ma which is half an Amp)etc.

As long as you get one that is 12v @ 2.5 to 3 amp it will be fine.
You could buy one with a higher current rating like 4,5,6 or more Amp's as long as it's 12v DC. The set will only use the current that it needs to function so I higher current won't hurt. It's the voltage you have to make sure is correct. If you do buy one with a higher current rating it will probably last longer because it wont get so hot.

The socket for the AC power supply is located RIGHT ON the cord that plugs into your tower/graphics card. I just bought one today at the thrift store, ** power cord, but was looking for the input myself and found it there. Hope that helps.

as you say that old speaker is working from the same tower means your computer is ok.

the problem is in speaker only.

plz chk that while shifting some wire must have broken or loose or speaker not connected properly.

ultimately chk connection.
