Try 10171. I got that code to work with my television (LC320SL1) even after Comcast told me they did not have a code.
Unfortunately there is none. Comcast apparently does not support remote control codes for recent Sylvania LCD TVs. Apparently Comcast believes the small number of Sylvania TV's does not require their small investment in coding to be worthwhile.
Screw Sylvania for making a TV with a proprietary remote code!
Get Dish and see if theirs works.
I've been trying to get a comcast remote to work, and nothing seems to work. Now I'm forced to pay the geek squad a hundred bucks. I'll keep in touch to see if that works!!!
Nothing works. Comcast sucks. I wish sylvania would sue comcast for being so discriminatory in its business practices
Sylvania comcast codes. 10054 10030 10171 11271 11314 11963
Dumb. Comcast doesn't make hardware. The boxes are motorola and the remotes, I think are made by an oem that is tied with RCA, this is why they will work by default with RCA tvs. No one should sue anyone for this. You can't have one size fits all always. If you could prove that rca disliked philco who was tied to sylvania, that this is some conspiracy from the 1950s because philco stole rca patents, then perhaps you might have something. I made that up, but either way, not a cable companies fault.
