No sound on my element tv. I TRIED both remotes (cable & tv remote). The cable tech came out & tested it and said it must be the tv because it's not the box. What could it be the tv is like 9 months

Try the code 052.

SOURCE: Need 3-digit code for tv remote

I'm looing for the TV brand to choose so I can find the right 4-digit code for an Element TV (Element is not listed)

SOURCE: Sharp TV (LC52D64U) remote control Comcast cable (DVR) box ?

I had the same problem with my remote. I would enter the code and there would be no response from the remote. I looked up the manual for the other comcast remote and the codes are 5 digits instead of 4. Try codes 10093 or 11602. The reason why there is no response from your remote is because it is waiting for you to enter the last digit of the code. Hope this helps.

might be able to use the cable co remote and autosearch thru the codes, but its too hard to explain, the cable tech should have ran that procedure. unfortunately, rca has 50 million models. it is common to have a tv and yes rca for sure, to not take the codes. sometimes the tv is too new for the cable company remotes to work. i am leaning toward the tv too new theory. give it six months and i bet there will be a new remote version.

I am having this same problem with our Mitsubishi LCD Flat Panel TV, Model LT-46246 ans our Scientific Atlanta remote cable box, same model as yours. We cannot use the remote at all to change the channel. I called Mitsubishi and they said they have never heard of this. I find this incredibly hard to believe. Time Warner, our cable provider says that it is not the box because it works when not hooked up to the TV. What a pain. I would love to hear if anyone else is having this problem or has a fix for it.
