I was given a 15HPB monitor withoput the power supply. I was told that it didn't work. I do not know if it was the power supply or the monitor itself that is bad. I don't see an easy way to open it up. Does anyone know the power connection on the PS/2 connector (+12V, +5V, grounds). I picked up a similar power supply (+5V, +12V, at the required 2A) for $5 at a hamfest. However this one has a regular keyboard connector. What are the odds that a old style keyboard connector to a PS/2 connector would match the power supply pins. I don't want to spend $35 on ebay for the correct supply, if the monitor could be bad.
The monitor requires BOTH 12V and 5V @ 2 amps with a PS/2 (keyboard type connector). A single voltage p/s will npot work.The monitor requires BOTH 12V and 5V @ 2 amps with a PS/2 (keyboard type connector). A single voltage p/s will npot work.

Re:
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.

It is understood that your AOC monitor is not working, you had followed troubleshooting steps like connecting VGA and Power cable from monitor to computer and the monitor panel light is ON but still no display. You have tried connecting another monitor and it is working fine, so it is advised to contact AOC support to check if the monitor is under warranty and it can be replaced or repair. To help you do these, please follow the link given below: http://us.aoc.com/aoc-technical-support/?page=contact-technical-support
What is the model number of the monitor? Of course you should know that the back light inverter uses high frequency and it may be beyond the range of your meter
There are 2 basic reasons for the "No Signal" message.
Loose video card inside the machine- if you're machine didn't come with on board video or if you are using an independent video card instead of on board video, the card can unseat at times, either due to movement of the machine or pulling on the video cord
Loose connection between the video cord and/or monitor and/or machine. Unless the plugs on both ends are secure (including tightening both screws to prevent loss of connection), the cord can dislodge just enough to interrupt your connection, causing a "No Signal".
If neither of these is the case, try hooking up a different monitor (if equipped, you can use an HDMI cable to your TV) to see if the "No Signal" message persists.If using a different monitor works, the issue is your Acer Monitor.
I'm assuming this is a desktop motherboard? Make sure the plug for power is connected and tight. It is refuses to work see if you have another slot and try moving it to the free spot.
If it still doesn't work: 1. make sure your monitor is connected properly and turned on 2. if possible try the monitor on another machine to make sure it's not the monitor itself
If the monitor works correctly on something else and you've tried the above than it's likely that the video card itself died and needs replacing.
Do the following: Step 1 -Check the voltage switch (if it has one) on the back of the PS. Make sure it matches your home voltage. If yes proceed to step 2. Step 2 -Check for heavy dust/debris inside computer case and inside PS. Clean with can of air as needed to prevent possible overheating. Step 3 -Check all connections to motherboard and try restarting again. Look for the green light to appear on the PS.
Notes: -Improperly installed or incompatible memory modules will also keep PC from starting up properly, although this usually is communicated through a series of beeps at start up. If no memory upgrade has been made recently, this is probably not the issue.
Most power supplies last well beyond other PC parts. Finding a replacement should be pretty simple. A used PS will do just fine. Test before buying unless New In Box.
Connect the monitor cable to the 15 pin monitor receptacle on the rear of your PC
Connect your PS-2 mouse to the PS-2 mouse connector (usually colored green) on the rear of your PC. (If you have a USB mouse, connect it to any USB receptacle on your PC)
Connect AC power cords from your AC power (wall) receptacles to your monitor and to your PC' powr supply's AC connector.
This completes the installation, you can now turn on the power switches on your monitor and computer.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty
One bad lead can cause a computer to fail to detect a hard drive continue on a cycle or to shutdown
Test all leads that attach to your hard drive including electrical extensions,IDE,SATA and
the leads from your motherboard to your hard drive make sure they have a secure connection and are not faulty or just replace them there probably old and faulty
problems
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty or just replace them they are probably old and faulty ?
hope this helps
It may have damaged the power supply(PS) and a fuss is possible, but you may not recognize the fuss on the circuit board. Open up the monitor and take a look. Also take the Number down off PS and look-up on line. A used/refurbished PS. eBay a good place to look
Try taking out the ram and reinserting it also anything that is in the PCI Card slots.. other solutios is take and unplug each device and see if the boot up changes it will sometimes give a read code it might help eliminate the problem
Power supply went bad (6.5v on the 5v rail) and fried my motherboard. I read where Mad Dog, Inc was terrible at returns and replacements and the BBB rated them as one of the worst. I threw up my hands and just ordered a new one from a different Mfg.
The monitor requires BOTH 12V and 5V @ 2 amps with a PS/2 (keyboard type connector). A single voltage p/s will npot work.
Do you know where we can buy a power supply from? We have the x2gen 19" MONITOR. Thanks.
