The Innovage code list gives LG (Goldstar) TV only codes: 004, 005, 009, 056, 057, 155, 156, 172 . A manual code search is also available. Turn on the LG unit, aim the remote at the TV and press and hold Code Search until the LED lights up solid red. Push the TV button on the remote and then slowly press the on/off button until the TV responds. Then press Enter to store the code on the remote.
There is a link to the manual here: http://www.blurtit.com/q717681.html

The only other issue is the age of the remote. Universal remotes only have the codes that correspond to devices released 6 months or more before the remote was programmed. If your TV is newer, then you need a newer remote.
I hope this helps.
