What is the DC voltage for a ADI Microscan monitor, Model # M17AWA?

I have 2 or 3 power adapters but not sure which one would be required for this. I relocated from one town to another and everything got tossed around.

My monitor want come on acer 9300-5005 laptop


1. Take the battery out of the laptop & try to turn on the laptop using power adapter only. If the computer turns on, then the battery is defective & needs to be replaced.
2. Make sure the power adapter is not defective. Test the output voltage of the power adapter using a voltmeter. Compare the voltmeter reading to the nominal value written on the adapter or the laptop.
3. Make sure the DC jack is not loose or broken. A loose DC jack will need to be re-soldered. A broken one will need to be replaced.
4. If you have another processor which is compatible with your laptop's model, try swapping processors & test to see if the laptop will work.
5. The power button could be bad.
6. The motherboard could be defective & needs to be replaced

hope u r a professional..as u r handling chip-level repairing of monitor, knowing itz hazardous n dangerous..

however, check thoroughly for dry soulderings..(esp. at the crt base)..[this chance is maximum]..
see if the base is loose or faulty..
yes, it can b the 'chroma ic'..but don't ignore the associated components..(esp around the base)..
check video amplifier n sub section..
the colour diodes, transistors n resistances at the base..

for better supervision contact ur system admin/vendor....

No' it's not powering up at all now, can you help' after changinng ac-adapter & battery


Laptop is dead. How to troubleshoot the problem.
In this post I’ll explain how to troubleshoot a dead laptop and find the problem. The following troubleshooting tips are not model and brand specific, they should work for most laptops.
Let’s take a look at two different scenarios.
Example 1. The laptop is absolutely dead.
When you plug in the power adapter and press on the power button, there is no signs of life at all. The laptop will not make usual noises, LEDs will not light up, the fan will not spin, the screen is blank and black, etc… In short, the laptop is dead.

What you can do in this case?
1. Make sure the wall outlet is working and the laptop DC adapter is getting power from the outlet. Try another wall outlet.
2. Test the laptop DC power adapter, make sure the voltage output is correct. You can test the DC power adapter with a voltmeter.
3. Let’s say the DC adapter is fine and the adapter outputs correct voltage. In this case unplug the power adapter from the laptop, remove the battery, wait for 1-2 minutes, plug in the adapter and try turning on the laptop again.

OK, you tested the adapter and it’s bad. If you decide to replace the original DC adapter with a generic one, you’ll have to follow this rule:
The voltage output on your new adapter has to be exactly the same as on the original adapter. The amperage on the new adapter could be the same or higher.

If nothing helps and the laptop is still dead, apparently the motherboard is fried or there is a problem with the DC power jack. It’s possible the DC power jack is broken and the motherboard is not getting any power from the adapter. In this case you’ll have to disassemble the laptop and replace the power jack.
Example 2. When you plug the DC power adapter and press on the power button, the laptop starts making normal noises, the LEDs work properly but noting appears on the screen. The laptop will not start.
First of all, take a closer look at the LCD screen. Look at the screen under bright light. It’s possible that the image is still on the screen but it’s very faint.
If there is no image on the laptop LCD screen, test the laptop with an external monitor. Connect an external monitor to the VGA port on your laptop and turn the laptop on. You can toggle video output between the internal LCD screen and external monitor by pressing Fn and F4 keys simultaneously on HP laptops, Fn and F5 keys on Toshiba laptops, Fn and F7 keys on IBM laptops. Other laptops may use different key combinations.
Let’s say the external monitor works fine but the internal LCD screen has no image at all. If that’s the case, your problem could be related to the LCD screen or the video cable. Also, make sure the video cable makes good connection with the motherboard and the LCD screen. Try reconnecting, reseating the cable.
In my case, both internal and external monitors were absolutely dead. Neither of them had image. That means the problem is not related to the LCD screen or the video cable. From my experience I know that this problem could be related to the laptop memory.
Try reseating the memory module, maybe it’s not making good connection with the memory slot. Try cleaning contacts on the memory module with pen eraser. Try moving the memory module into another slot. Try replacing the memory module with another known good module, it’s possible that your original module is dead.
If you have two memory modules installed you can try removing them one by one, it’s possible that one of the modules is bad. Try installing different memory modules into different memory slots.

In my case reseating, swapping the memory module didn’t help. I was pretty confident that my problem is not memory related and I moved on.
Try removing battery, hard drive and DVD drive and turning on the laptop without these components.
Also, try turning on the laptop with an external monitor when the video cable is unplugged from the motherboard. If the laptop start with video on the external monitor, apparently there is something wrong with the laptop display panel.
Finally, disassemble the laptop and removed the motherboard.
1. Motherboard. Like on most laptops, in my case the video card is integrated into the motherboard
2. CPU with heatsink and cooling fan.
3. Known good memory module.
4. The power button board witch you need to turn on the system.
5. Working DC power adapter.

Still cannot get any video on the external monitor. The system turns on, the cooling fan starts spinning but there is no video.
At this point I’m 95% sure that the motherboard is dead. CPU failures are not very common, so it must be bad motherboard.

Power failure issues


The specs for this monitor is a 60 Watt, 12 Volt, 5 Amp power adapter. The voltage must be the same. You can always get an adapter with a higher Amperage rating, but never get one with less, as this can overheat the adapter and damage it. I was not able to locate specs on whether the voltage to the monitor is DC or AC... most are DC. If this is the case, the observe the polarity at the monitor. Power adapters have a positive and a negative... center and outer contact, Make sure that the power adapter matches that of the monitor, else it will not work.

Adi microscan monitor 17 green screen


this is a loose cable from the monitor vga. please make sure the cable is secure from THE monitor side

It is a connection somewhere. It can be the cable, monitor, or video card. If you another input on the monitor i.e. DVI try that with a different cable. If there is another output on video card try that. Mix them to test. trial and error.

Odds are there are some smashed pins.

What voltage is the dc adapter?


You will need at least a 4 amp rated regulated 12 Volt power supply.
These are commercialy available from most electronics parts suppliers.
They come on a circuit board. You can mount it in your own case and
use the original Viewsonic wire end. If you do a google search for 12
volt reglated power supplies you should find many of these.

However, with a second-hand Sprint AC adapter with 3A,
12v adapter, the screen blinks on and off
intermittently. Obviously there is some difference here between a class
2 adapter and a power supply box.

ADI A905, No Display, but appears to get signal


I have the same problems as you. I found the only fix is to physically unplug the monitor from the wall outlet, and then it plug back in. Sounds like an internal design flaw.
