    Hi,
    I have a 19-inch Acer LCD monitor with a bad power supply. I understand the problem to be bad capacitors on the power supply unit/board. I can replace those capacitors but I can not open up the monitor. It has a special key hole (lock) in the back & I can not find the tool/key to open it. Does anyone have any idea (short of drilling a hole in the back of the monitor to pick the lock)?

    The screen lights up, the ACER logo flashes, and then it powers off after 1-3 seconds. If it's left plugged in, it will continue this process.

    You've posted that the MB must be repaired and yet no specifics are listed! Do you have any specifics to aid others in repairing the AL1916?

It is inside the LCD the at the main board. You have to repair the board to make it function.

I think what you need is a "D" shell connector.. see if the one that fits your PC Power Supply will fit into the Monitor.. if so then purchase another the same. It's called a "D Shell" Power Cord.

No, it has a normal, seperate power cord. But the socket in the monitor is very small, it's a small round one. When facing the monitor from the back, it's located directly to the right of the monitor-stand, at the bottom-side of the screen. Just put the monitor on it's side to see it clearly.

It's all explained with pictures in your monitor's manual which you can download from the official website here: http://www.maginnovision.com/Support/Downloads.aspx?sn=464

I NEED APOWER CORD FOR DAEWOO L950


I can't find information online about your monitor, so I'll give you a generic answer for all monitors.

Almost all monitors use a C13 cord - the same kind used for a desktop computer. Some use a C7 (two-wire, like that used for some name brand laptop adapters) or a C5 (three-wire, used on other laptop adapters)
C13 image:
173-0602-e.jpg
C7 image: ac15wna-r.jpg
C5 image:
173-21103-e.jpg
These images were lifted from the Mouser Electronics website (AC Power Cords Mouser ). They also carry C13 cords with right-angled plugs, which may be more convenient with some monitors.

There are a very few monitors that use an external power supply, which is like a laptop computer power adapter. If this is the case, the voltage and current requirements for the power supply should be on the label on the back of the monitor, and the only other thing you have match is the plug on the power adapter output cord (it needs to fit the power jack on the back of the monitor). Note: the voltage of the power supply must be the same as that shown on the label (usually 12 VDC) and the current rating must be the same or higher. If you don't see the voltage and current listed on the label, look closely at the power jack - the numbers may be molded into the plastic next to it.

It is rare to find a monitor with a permanently attached power cord. If this is the case with yours and it is damaged, do not attempt to splice it outside of the monitor. Put a replacement plug on if the good part of the cord is long enough, and use a good extension cord. Otherwise, you should open up the case and replace the entire cord. You will probably have to get a connector for the part of the power cord inside the monitor also. (If you are good with soldering, you may be able to splice to this connector, using heat-shrink tubing to insulate the connections.)

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

Power cord issue? Black Screen with image issue?


The powere cord you are using is fine (the cord is made to handle the 10A load, you are only drawing 1.5A). The monitor uses switching mode power supply that can handle any voltage INPUT between 100v up to 240v. More likely to be bad caps in the power supply. See example of failed Westinghouse due to bad caps: http://s807.photobucket.com/home/budm/allalbums

I tried turning on my monitor and it wouldn't turn on. I checked the power cord and everything was connected correctly. Any Idea;s?


The first step is to make sure the plug you have the power cord plugged into is supplying power to the monitor. [surge protector? Check the switch or the reset button]. Check for the powered on light, usually in the power on button on many computer monitors. Yellow usually means a bad connection with the computer. So the monitor is actually on, it just appears off because you have a black screen. Check the video cable linkage to the back of the monitor and the computer's graphics card or digital video out.

If when you "power on" the monitor's on light does not light it means that power is not getting to the unit and you could have a bad power cord. If it is of the universal type that unplugs from the unit you can swap out for a new cord to test this [some monitors have external power supplies as part of the cord and this could be the problem]. If swapping it for another works than that was your problem.

Many monitors though have their power cords mounted via chassis clamps to the unit and have internal power supplies and are not end user serviceable.

If power is making it to the unit there are a handful of possibilities. Unfortunately the majority of them, at that point, involve dis-assembly of the unit's outer casing and is not advisable to an untrained end user. A service call would be required at that point.

How to know if the monitor is totally dead?


Generally, if the power light (LED) doesn't come on and there is no screen display with or without input signal, it's dead. Probably a failed power supply.

Monitor dead


The monitor has a bad circuit shorting out it's power supply. Could also be faulty electrolytic capacitors in the power supply.
Good luck.

PS/2 power supply connection


You seem to have an oddball monitor if what you describe is correct. The power supply to a monitor[Display Screen is that what you mean?] is either direct to main power- in which case the power cord is either built in with a power plug for wall socket, or has a socket on the back for a separate main power cord. Or is powered from a low voltage converter that delivers low volts usually via a coaxial plug like this illustration PS2 connection does dot come into the equation as far as I know unless you have got hold of something unusual. Tell you what take a shot of the back of the monitor and lets have a look see mean while here's is a shot of a typical low voltage power supply available anywhere.
