Normally, the polarity is molded next to the connecter hole; it may not be real easy to see.
If you have a digital multimeter with a 'diode' position, most devices have a diode internally installed to prevent damage in case of a bad substitution and the meter will show a value of somewhere between 500-800, typical would be in the mid-600s.
If you find that, then the meter is currently causing the internal protective diode to conduct as it would if the WRONG polarity would be applied and most meters will supply a positive voltage to the red lead for diode function.
Commonly, the center is the positive contact but this sure isn't certain.

If it uses AC adapter, then check the DC voltage at the DC plug to see if you get any voltage, if it use Direct power cord then it may have blown fuse inside the monitor, then you will need to open up the monitor.
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

I need to know if there is still some were to purchase and Ac Adapter for a Balance LCD Monitor CM2019?????????


All you need to know is:
- The output voltage (usually 12V)
- The rated output current (usually above 5A)
- The plug polarity (usually plus on the inside)
Then just purchase any replacement AC adapter that has the same voltage, same plug polarity and rated current preferrably more (at least 120%) of the original.
That's it.
You can buy them online, for example at http://www.12vadapters.com/

My B70A Hyundai will not power on. The green or amber light will not power on. I wanted to make sure I have the correct Plug. Are there any drivers or is it plug & Play? Thanks Lesa LesaBrown1@aol.com


This monitor is plug and play but the driver (or lack of) is not the problem.
Its either your the power supply or the monitor itself has an issue with its
internal power distribution circuitry. First make sure your power supply is
operational. The original 120V AC to 12V DC 3.3 A power supply for the
B70A had a green LED on the brick itself. You will find it on the top right
corner of the brick, on the end where the DC cord comes out (opposite
end from the AC input) If you have the AC cord plugged in the wall, the
LED should be lit. If it isn't, the brick is no good, and should be replaced.
Any 12 VDC adapter with an amperage rating of at least 1A but no greater
than 3.3 A having the same size tip (with correct polarity) should work.
If you have confirmed that the adapter IS functional and the monitor LED's
still remain off, the internal power distribution circuitry of the monitor is
damaged, probably caused by burst or leaking capacitors.

Hi yes it looks like the inverter has failed and will need replacing, or if your compitent enough you can fix it at board level. The usual suspecs are a small SMD fuse on the inverter board / power supply board and/or buldging capacitors which look like blue or black cans.

hope this helps.

I did not have a power adapter for my lcd monitor but after 2 weeks of searching stores, internet and universal adapters I found the power adapter for my specific monitor on ebay. If that doesn't work I would suggest a universal power adapter.

Replacement External Power Supply


So the old power supply doesn't have the output voltage, current and polarity noted on the label? What a ripoff! *grin* Did you look on the case near where it plugs into the monitor? Sometimes that will tell you the voltasge and polarity. Poliarity? Get that one wrong and the monitor could be cooked instantly! But it's usually positive. I found a completed eBay listing that had this info: "the power supply which the seller used to power up this Planar Flat Panel is inventoried as follows: ViewSonic 12V Power Adaptor Model # SYS1126-5012" I looked that one up, and it's listed as 12V at 4.17A. PC Hub has them for $28.62: http://www.pchub.com/uph/laptop/345-19804-2285/AC_Power_Adapter_5V-12V_Others_SYS1126-5012.html Good luck!
