You can find codes for the remote here:
http://www.urc.philips.com/ . Then look up the CL043 and click on the remote code finder. This is also called the SRU3004WM by Philips.
A Westinghouse TV should responds to one of the following codes: 0915, 0013, 1216, 0300 if the TV was released 6 months before the remote was programmed or earlier. (Whte Westinghouse codes are different.)
If those codes do not work, there is a manual code search option. With the TV on, press and hold Setup on the remote until the red indicator stays lit. Then press and release quickly the TV button on the remote (the LED will blink once). Then press the Channel Up button until the TV responds (up to 300 times). If you overshoot, press Channel Down to go back to the previous code. Press and release the Mute button to set the code. Check if the remote performs all the needed functions. If it doesn't, repeat the above steps to find another code.
I hope this helps.

(if the remote is older than the TV, you may need a newer universal remote.)
