PLEASE HELP!

I have purchased a refurbished FLM-2011-HDTV Monitor. It did not come with the remote. I have read all posts above and cannot get my Charter cable / Scientific Atlanta universal remote (3 digit codes) to program to this TV. I have even tried an RCA (4 digit codes) remote and also cannot find the right code. I currently have it plugged into to aux power outlet on my cable box so I can turn the TV off by turning off the cable box, but I must get up and physically turn the TV on by hand and it's getting annoying.

Does anyone have another code or can someone tell me of a universal remote that might work with this TV?

THANKS!
