Most monitors have a light on them that indicates that there is power running to them when the monitor is turned on. If this light is not on then you either have a defective power cord, or the monitor itself is defective. The only way you can really determine what is the case is by trying a new power cord for your monitor. If you find the monitor itself is defective it would most likely not be cost effective to repair it unless it is still covered by the manufacturer's warranty or a service plan.

If the light for the power to the monitor is on, you are not seeing anything on the monitor; the problem is likely to be with the monitor cord or the computer's graphics card. I would first try a new VGA cord, and if that doesn't work you could try installing a new graphics card.

If you continue to have this issue, or you don't want to troubleshoot it yourself, you could bring it to the Geek Squad® precinct in your local Best Buy® store and they should be able to troubleshoot the issue for you (make sure you bring the computer with you too). I hope this helps!

An open box item can be merely an item that a customer decided they didn't want, and then returned it to one of our stores. It can also be a product that was damaged aesthetically, and was exchanged due to this damage. An open box item can also be an item that was defective, returned to the store, and then repaired. If the item was repaired it should state this on the open box price tag, and any aesthetic damage should be visible.

An open box item is sold as is, which does mean that the paperwork might not be with the unit. It depends on the terms of the manufacturer’s warranty as to whether or not their warranty will cover an open box item, but we will honor the terms of the manufacturer's warranty if they don't in regards to open box items.
