Quoting admiralWillyWilber,
My power cord does not look like a regular cord. It looks more like a laptop cord.
That's like my LG 27" monitor's power cable... a regular plug to the supply, a power adapter to reduce current, then a small single pin plug going into the monitor. Before I got it I'd only ever seen monitors with a regular power cable the same as those going to the PC itself.
Thing is, see if you have a spare adapter with the same power ratings and same size pin. Perhaps you could try it to see if it is in fact the cord at fault. I have a spare for my monitor now. I often keep power adapters from old/dead hardware, but I found my spare monitor cable at a weekend market for 2 bucks. Though it was originally for a Toshiba appliance it does the job.
