I have a dell 1702fp lcd and the power supply has shorted. It outputs 14v 3a

Would i be able to use an IBM ac adapter that outputs 16v 4.5a ??

The connector is different though... is there any way i can cut the end and just hard wire it to the lcd?
If yes, then can someone point me in the right direction?

Thanks in advance

More current is ok,, but is that 14 AC it states on pak?

and is the IBM 16 AC as well?

Thanks for the response
yes that is what the ac says

How would i go about connecting the IBM 16 AC to the LCD?

Would i just strip the end of the ac connector and solder it in the lcd power slot? Various methods would be appreciated :-D

you could simply cut the connectors off both,,, and splice the orig input connector onto the lead from the IBM pak,,,

can you humour me and put a pic of both paks showing plugs here?

No camera as of now but

Dell connector
http://i22.ebayimg.com/01/i/06/4a/77/d8_1_b.JPG

Power Jack dimensions:

Inner diameter - 4.4mm

Outer diameter - 6.5mm

Comes with pin in the central connector.

ok then you cut the dell plug off about 6 inches back from plug, same for ibm pak and just splice the dell connector onto the IBM paks lead,,, it is ac so should not matter which wire is which....

its is 16 volts versus 14,, so check when you fire it up for parts near input, for heat,, should be ok tho,, the board has all the voltage regs onboard, and should handle the extra herbies,,, I cant gaurantee that fully tho..

Thanks elken
I see that you're omniscient so hopefully you might have an answer for my other thread too about antiglare at

Thanks again

hehehehehheh yep I am '''''Q''''''

Um. Are you sure it's ok to use a different voltage AND a different amperage? Why would they bother having different power packs if you could just mix and match at will?

Personally, I'd probably invest in a new Dell branded power supply. It'll probably cost you $50, but it might be worth it...

Hey guys, this is what i did, tell me what you think (uh oh) lol

I strip the ibm 16v wire and slipped it into the center (the connector on the dell 1702fp is 6.5mm with an inner slot of 1.3mm) of the power slot of the dell 1702fp

Should i test it by powering the backlight?

There should be two wires connected (ground/negative and positive).

On every cable I've checked the positive was in the middle and the negative was on the outside. I can see the outside wires in the pics, it sorta looks like shielding, but it also completes the circuit.

It'll be hard to get both wires into the plug without shorting them. You're much better off cutting the other cable and splicing the wires together. Make sure they are connected well, if you can crimp them that would be good, or solder 'em, or if you have to: twist them very tightly.

If you don't want to cut the other wire, you can just stick the wires into the plug, just make sure they are only touching what you want them to. The inside of the plug on the monitor is going to have 2 metal surfaces (probably a spike looking thing, and a ring of metal along the inside. The spike it probably the positive, the outer ring is probably the negative. The negitive/ground can be connected to another grounded part of the screen. For instance; you could clamp it down with that screw on the right side of the top pic.

Do you have access to a soldering iron?

If you do, you could probably desolder the entire cable from the broken AC adapta and solder it to the substitute adapter. This way you don't have a bunch of wires twisted together (and all the connections will be better).

Tend to agree with Hirudin. The high amperage of these power supplies is to drive the backlight. However in the PJ application, the backlight is not needed. Higher amperage power supplies cost more. A power supply between 500 ma and 1a should be sufficient to drive the controller board. I would be more concerned about matching voltages. If you have any computer surplus stores nearby, you can probably get an exact voltage match at sufficient amperage for about $10.
