What is the code for Philips sound bar css2133b?

You may try these codes: 0177, 0083, 0983, 0084, 0184, 0277, 0377

Try these one also 1214, 0598, 0277, 0298, 0442

If all else fail, try 9999 and 0000.

If by chance it still does not work, it means the universal remote is not compatible with the sound bar.
