Neither of those links work, and as you didn't post the model number of your remote, I can only guess which one you have. I'm guessing it's the 15-2103, which is a UEI remote, so the Toshiba TV code is TV/0156, that's the code that should work your Apex TV. And before you ask "how would that help", just try it, if it doesn't work, then come back for help.
