It is a good solution, but only use the Analog Volt Meter or multimeter (just \$8 dlls in a electronic store) and make the first steps that guest wrote:
"Plug the red lead into the center post of the adapter and touch the black lead to the outside ring. With a DMV it should show a positive voltage if the center post is Positive or negative voltage if the center is Negative. With an analog meter (red - center) positive voltage, (black - center) the needle tries to swing to the left of 0 volts" it is enough.

Good Luck!!!

Use a DMV (AKA Digital Volt Meter) or an Analog Volt Meter) to check the polarity of the plug. Not sure how to use a meter? Plug the red lead into the center post of the adapter and touch the black lead to the outside ring. With a DMV it should show a positive voltage if the center post is Positive or negative voltage if the center is Negative. With an analog meter (red - center) positive voltage, (black - center) the needle tries to swing to the left of 0 volts. Being 12VDC don't worry about being shocked the voltage and current is low enough that if you were to get shocked it feels like a little tingle and is direct current not an alternating current (AC) which if handled improperly will cause your heart to stop. Remenber it's not the voltage that kills, it's the amount of amperage. (12VDC 3A -- AC Adapter) vs. (12VDC 700A -- Car Battery) Car battery wins !!! You can weld metal with a car battery but not with the AC adapter. Rule of thumb, You can always under supply the amperage just not over supply it except with fuses. Fuses were designed to limit the amount of amperage that the circuit can handle. Putting a smaller amperage fuse might get by for awhile,but will blow instantly during a power spike. Replacing with a higer amperage fuse will not allow the fuse to blow and cause the circuitry to overload and cause a fire. (Bad !!!!! Do not ever do this).

Hopes this helps.

What type of coaxial power connector is on the circult board to the Mag Innovision model LT 565 LCD monitor? I need to find a replacement part.

Most monitors use barrel type connector with 5.5mm outside diameter and either 2.1 or 2.5mm inside diameter. You can get both of them at Radio Shack. You do not want to use the 2.5mm if the center pin is 2.1mm it will not make good contact.

Alternate generic 12 volt power supply

OK, usually, the Center, PIN is always POSITIVE, The OUTER, Screen, is Always NEGATIVE. This "Polarity" is also usually indicated on the Power Supply itself, and Often right beside the "Power Socket" it is imprinted, with a diagram, of a dot inside a crescent., there is a Positive mark, to the Dot, and a Negative mark to the crescent. Your supply, will have to supply about 4 - 5 amps of current, at the right Voltage, I would imagine, make sure you have your current limiting set.

If you're looking for a generic ac adapter, the specs of mine are: 19vdc @ 200mA, NEGATIVE polarity.
Important...the center pin is NEGATIVE (most center pins are positive).

MAG LT776s Monitor power cord

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.
