You may have already considered this, but maybe the remote isn't set up for that TV. Is it programmable? Can you borrow one with universal capability and try to set it up for that TV? Maybe someone has a DVD or Satellite Receiver remote that has a TV or AUX output you could try to program for your TV.

OK, do you have an oscilloscope available?
Try locating the IR receiver and check it has 5V or 3.3V supply.

Can you post a picture of this small board? IR sensors typically look like this:

You should see some varying square wave (on a scope) when IR signal is received on one of the pins of that device.

Right hand device with three pins. Check pin 3 for Vcc (3.3V or 5V) with respect to chassis ground (black on the chassis), and pin 1 or 2 for signal using a scope and pressing buttons on remote.
