You can do a code search on your remote to find the code. Here's how:
Turn your TV on, press and hold the TV button on your remote until all the lights at the top flash, press the large red power button, press channel up until your TV turns off. If you go past the code on accident, just hit channel down until the TV turns back on. Then press pound (#). The TV light will flash 3 times and the code will be stored in your remote.
