SYLVANIA VS UNIVERSAL REMOTE

Hello. I have lost my remote for my Sylvania SRT 2319 and am trying to program my Time Warner Universal remote to work with it. I have found the code and the remote will power on and off the TV but it will not control any other features. Any time I press the channel key or a number key the CBL (cable) device button blinks, like it's not registering as a TV button. Does that make sense? What can I do?

Electronic Catan

I want to create a customized Settlers of Catan board. For the purposes of this question, it could also be a custom Monopoly board. I want the pieces ( cities / hotels ) to light up when they are placed on the board. I know I would put LED's in each piece, but besides that, I am not sure if or how I could power up the LED's. I am not an electrical engineer, but magnets, watch batteries or inductive charging sound good to me. Help me make an awesome electronic board game!
