I have a Westinghouse model LCM-17v2 flat screen computer monitor that someone gave me but there is no power cord. This is not a standard power cord (you know, the type with 3 holes), it is one prong (it reminds me of what I use to charge my cell phone). I have been unable to find it online and even asked a website for their help and they showed me a photo of the standard 3 hole power cable. I sure hope you can help.
