Need a "Comcastic" guide? The Great Mog_ur will make Comcast issues disappear.
I'm a Comcast Customer service agent in the South Florida region for the last 8 years.. If there'are problems with your service, questions about the best deals and why the Tripleplay packages are such a money saver, or general "what's coming out now" questions... let me know and I'll do what I can to help you.
We do not have a listing of codes for a Seiki brand TV. Is it made by another company like Sony or Panasonic? If so, you can try those codes to see if they work. If it is its own brand, then you would need to search for the code on the remote. Press the TV button, then press and hold the Set button until the TV button blinks twice. Then press the numbers 991 followed by another 1 and the TV button should blink twice again. Press the gray power button at the top of the remote and then aim the remote at the TV. While aiming at the TV, press and release the channel + button, release, press, release. ... and so forth until the TV shuts off. Once it does, you should be able to hit the gray power button again and the TV should come back on. Please note, there are some TV brands that will not program to the Comcast remotes. In that case, you would still need to use your TV's own remote to turn it on and control the volume. I hope this information has been helpful.
