Hello there: Most of the computer stores or a electronics store like office depot or radio shack or walmart or k-mart ect ect ....will have these cords Furthermore if you have a second hand store in your area they might have them there too Hope this is very helpful for you> Best regards Michael
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.
on the specs from ebay I see you need a 12v dc 5 amp ac power adapter . normally they have an led , but if you can't get power you will have to verify that you have the 12v at the tip, you will need a multimeter or 12v bulb connected to the end. if your getting power then the panels circuit is at fault. talk to a local geek about checking it out.
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.
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:
This one should work for you it's the same voltage and amperage as your unit. 19VDC 3.16A Any standard power cable from an old printer or computer will work with one of those PS's.
The only thing you need to check before you buy is the polarity of the barrel connector. I looked on the net but could not find out that info so look at the jack where the power plugs into the monitor. You might see a little diagram showing a + and - signs. If the line coming off the + sign goes to the semi-circle than the barrel is positive and if the - goes to the SC the barrel is negative. Ask them before you buy which way that one is. As long as they are the same you will be able to use that PS.
