Take a short piece of track and connect it directly to the TIU channel. A "trick" here is to use about 30 feet of wire to connect the track to the TIU channel. Power the channel with DC at around 16-18 volts, obviously you have to use one of the fixed channels. This gives you the best chance of getting PS/3 files to load.
The fact that you're loading something suggests the board may not be bad. If only the name doesn't show up, is this the original board? New boards come with a blank name, and to load a permanent name, you need the dealer loader.
