LCD Monitor does not power on.

Honestly it sounds like something is going bad in the monitor (my guess would be either the main power supply or the backlight power supply) and you would either need to know electronics or know someone who knows about repairing electronics to fix the problem without replacing the monitor.

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

Problem seemed to be a short in the power cable to the monitor. Replaced the power cable and for the time, the monitor is working correctly.

Check the information at Viewsonic's website regarding their warranty:

http://www.viewsonic.com/support/warranties/limited-warranty/

If you have your proof-of-purchase and it shows the monitor is less than a year old, it would be covered. You would need to follow the procedure on their website to have the unit repaired or replaced, but it would not be your job to try to fix it.
