Power indicator on, but nothing else

Question

I just bought a used Olevia LT23HVX 23inch TV. It is in excellent shape physically. It had no power cord, so I used one from my computer monitor. When I hit the power button a red indicator light comes on, but that is it. I have no remote either. I don't want to invest in a remote unless I know the tv works. Is there something else I can do to see if it works? I am not familiar with these TV's so I don't know if I have to have cable connected to it for it to do anything. Is this normal? I have it my office where I have no cable/satelite. Thanks for any help you can offer
