I have an Emerson lc320em8a and can not use my Direct TV remote to turn the tv on/off or control the sound.

Universal remote codes for Emerson Brand TVs are: 0004 0009 0044 0135 0049 0051 0189 0053 0147 0039 0130 0227 0233 0250 0252 0254 0257 0265 0266 0310 0325 0456 0040 0041 0042 0021 0023 0024 0179 0045 0025 0027 0030 0032 0034 0035 0037

I was successful in finding codes on this site that were not listed in the manual:
Direct TV Remote Codes

I have the same setup like you. Direct TV and Emerson LCD TV. The Direct TV remote stores a limited amount of codes and none worked on my TV. Sadly it's not something you can update. They seem to only stick with the popular codes. Welcome to the "head of the curve" like me. lol

Try with the philips this method:
Manually turn on the tv or the device to be controlled.
Push and hold the code search button until the red lights stand.Now release the button push and release the tv button,then you got to push and release the on off button until the device turn off stop push and release the enter button.
You might need to push the on off button 1 to 150 times.
Good luck
