Re: AC/DC Adapter

Hi, You would need an adapter that puts out 12 Volt DC, Output Current: 3.3 Amp and the Center Positive Power Tip (Output Power: 40W). The original ViewSonic adapter is M/N: UP06031120A Hope this be of some help/idea/ Post back how things turn up or should you need further information. Good luck and kind regards.

Monitor wont come lite on the switching adaptor is off.Is the adaptor bad or monitor bad? How do I get a new adaptor?Model # WDS048120

The lamp on the power supply adapter should be on the minute it is plugged onto the AC outlet without the DC plug connected to the monitor, if it is not on then the AC adapter is bad, you can check the DC voltage with a digital meter. Post back so we can guide you further.

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.

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.

Need cable and power supply

Power Adapter Input AC 100-240V, 50-60Hz, Output DC 12V/4.0A

This may help. Just make sure you have the right dc output mentioned on the back of your monitor (12v4a or 12v5a) if any lower your monitor will shut off after displaying for few seconds then electrical smell will come out from your ac/dc adapter. When it overheats it shuts off.

Daewoo monitor

If you know a little bit about electronics, then you can find or buy a multimeter to check the output voltage of the AC/DC power adapter (if it uses one, sometimes the converter/adapter is inside the monitor). In order to get a voltage reading from center "hole" of the end of the power cord, use a paper clip (thicker paper clip if you have it). If the converter voltage is good, then this monitor might be a warranty return candidate. Hope it's only a power adapter problem (you can find a replacement on Ebay) ZT3000 "Beta tester of "0"s and "1's"
