I have the Trutech "19" LCD-HD with DVD (PLV31199S1) and the advice above for using Goldstar codes worked with my Comcast Cable universal remote. The only problem I had is using all 5 digits as the Comcast remote instructions specify. It really only wants 4 digits.... the last four. I used 0178 and I'm good to go! If you read between the lines you'll see the first digit specifies the device you are programming and for TV's that is "1". The codes they listed in the instructions was 10178 so I just used the last 4 digits and it worked fine.
