AC power cord for a llyama LCD monitor model Prolite E433 .... the cord was lost when we recently moved. I know it plugs into a socket on the video adapter cable that plugs into the cpu.

Good Day Tricia,

I had to pull up you owner's manual to get the spec's on your cord, so if you need the manual follow this link:

Anyway after reading the spec's you need an AC-DC power supply that outputs 12volts at 3.3amps. What makes this difficult to find is the 3.3amps, most aftermarket power supply only go up to 2amps. So what's next? Well you can order directly through HP at this link:

If you do this make sure get part 8121-0740 if you live in the states, or part 8121-0731 if you live in europe.

The only other suggestion I can give is to bring the monitor into a radioshack and see if they have a 12VDC 3.3AMP (you can get a universal with higher amperage if needed, the monitor will only draw the 3.3 it needs even if it is supplied more) and the reason I say bring it in is so they can match the size of the plug that goes into the monitor, as there are about 20 diffrent diameters's. Again the problem you may have is finding one with a high enouge amperage.

I hope this helps

Good Luck

Hi...there,
Try replaced with a new AC Adapter. If it still the same...then you got a busted backlight inverter. To order a new AC Adapter go to this site @ www.3rd-rocks.com click on lcd parts. have a nice day!

Dim or dark display can be caused by a faulty inverter board or faulty CCFL lamp. The inverter supplies high voltage to the CCFL lamp, the CCFL lamp is a miniture fluro tube and these dim with age.
