I'd try it with a laptop and a few other TV's. Then you know if it's an issue of your TV, the converter box, your PC or the cable.

I recently purchased an HDMI to RCA converter box to be able to connect my PC computer or my 'Acer Iconia Tablet' to my OLD TV and play movie videos on it. It requires a 5 volt power adapter which I have. NOW when I connect to the TV I can see my desktop and the movie I'm playing BUT the vertical hold continually skips and there is NO colour. I talked to the vendor but they are at a loss as to why this would happen. Does anyone know or has anyone seen this happen before? I can't adjust vertical hold on the TV and it works fine otherwise.
Might the power source not be powerful enough? Do I need a special kind of RCA cable? (I have the standard red/white/yellow sound/video RCA cable). What else might cause this?
Here is a link to snapshots of my connections and a short video showing what the TV looks like when connected:
