I just registered myself on this forum so that I could say THANK YOU for the previous posts from Kubakai (on 03-13-2007), Superhooper (on 08-03-2009) and Motorbaby (on 05-11-2010). My remote quit working about a 45 minutes ago while watching Grey's Anatomy. Husband tried for a half hour to reprogram it using documentation from Comcast. He gave up and said we should call Comcast...but we all know that means ALOT of frustration. So I googled 'program Comcast remote to cable box' and lo and behold, this forum popped up. It took me a couple of tries (had to use the leading zero), but it worked! A BIG THANK YOU!

Hi, I have a Motorola DCH3416 box and a Comcast remote with the red OK button. 90% of the day, I have absolutely no problem with my TV or remote. However, I regularly have issues at night (around the same time, interestingly). The issue is that when my Sharp Aquos TV is off, the remote clearly is able to change the channels on the cable box. When the TV is turned on, the remote works for about 3-4 seconds, but then the box stops responding to the remote signals. It's almost as if there's something about the TV being on that is interfering with the workings of the remote during the night.

Comcast, of course, is of no help in this situation (they tried to explain to me that my wireless router was disrupting the remote signal...right). I'd greatly appreciate your expert advice.

Thanks!

This is a classic case of IR interference coming from your TV backlight. Either turn it down (or turn ambient sensor off), relocate your cable box or try one of THESE fixes.

Hi. I have the most basic comcast remote. Just number buttons, channel, volume, mute, set and power (black with yellow mute button and red power button). It works on my TV, but not on the comcast box, which is a Motorola Digital Adapter. It has no buttons on it, so my cable is stuck on one channel! Is there any way to get it to work again? THANK YOU!

The remote is setup at the factory to control the DTA.  One thing you cab try is a 981 reset.  If you do this, you'll need to re-enter the TV setup code.

1) Press Set until 2 blinks
2) Enter 981
The remote should blink twice

Hi, thank you for your time. This is a great forum, appreciate any assistance.

I just bought a Sharp aquos 60 LED TV, installed and works perfectly. I used the Sharp code on my Comcast remote, gray with red OK button. Everything works well, EXCEPT...

When I adjust the volume on the comcast remote, works great. However, when I click the up channel/down channel or virtually any other button on the comcast remote, it not only performs that function on the cable box, it also changes the TV volume down or up, whichever was last used.

Seems very odd, that the Comcast remote seems to have crossed frequencies with the Sharp TV, any ideas how to remedy? Did I explain it thoroughly enough?

Thanks again, for your help.

What setup codes are you using with both the Sharp TV and the cable box?  What brand and model is the cable box?

Thanks for your help.

The cable box is Comcast RNG 110, I am sorry I don't see a make (motorola, LG etc) anywhere on the box. I did not set the box up, so I don't know what the setup code for that is. I have 4 boxes in the house, all the same RNG 110, the 4 remotes all do the same thing to the Sharp TV, but not to the other Tv's I have, a LG, Panasonic and Sony.

I am using 10093 for the Sharp code. I have also tried 11602 and it also works but does the same thing to the TV, adjusts the volume when I press any button. I tried 10165 and 10386 and they did not work with the Sharp TV.

Thanks for any advice!

The RNG 110 uses the XMP IR protocol and 10093 is the Sharp IR protocol.  A protocol defines the pattern of on/off flashes of the IR emitter, including the modulation frequency, and the durations of the on burst and of burst.  These two protocols are different of course, but there are similarities.   Both use a modulation frequency of 38KHz (so does 90% of all IR controlled equipment).    XMP uses an on duration of 210 microseconds, while Sharp uses 260 microseconds, which are fairly close to each other.  However, the TV should be easily able to reject XMP signals.

Two suggestions:  
1) Try reducing theIR signal level reaching the TV by covering the TV's IR sensor with e.g. black tape with a small hole in it.  Or try a piece of fabric in front of it.  See if you can find a covering that allows the TV to respond to signals sent using TV mode on the remote, but doesn't respond to cable signals.

2) Perhaps Sharp has fixed this problem with a new release of firmware.  I don't know which model you have, but there is a firmware update available for many new Sharp 60s TVs.  The instructions show how to determine if your TV has the latest firmware, and how to update if necessary.

It makes sense to complain to Sharp.  The TV should not do this, and since there are probably a few million Comcast users who have boxes which use XMP protocol, they may have already heard about (and maybe fixed) this issue.

Thanks for the help. I finally contacted Sharp and after much ado was told I am being mailed a Firmware update on a flash drive. We will see if that happens, I will update.

I did purchase a Logitech Universal Remote which works with both TV and Comcast Cable box and does not have the same issue adjusting the volume, however I don't like the feel of it at all. The volume adjusts in increments of 2, and when I hit mute it mutes then un-mutes. It seems to send every signal twice, weird.

Thanks for the help, I will let you know if I get the Firmware updated and the results.

Ok so I got the flash drive with the Firmware update, installed according to instructions, and....


Didn't work. Same problem, sucks. Now I need to spend another hour on the phone with Sharp to try to see if I am the only one with a Sharp TV and Comcast Cable.


What a pain

Let's try one more thing.  It is possible that the RNG 110 responds to 2 different IR protocols.  The two setup codes are 01376 (GI Cable, used in Motorola equipment) and 01982 (XMP, used in newer cable boxes).  I would first blink back the setup code that the remote is currently using for cable, and then try the other one.  You'll probably need to use the 982 command so that the remote will let you change the cable setup code.

Hi there! I as well have spent 3 hours on the phone with Comcast this afternoon to try and "fix" my problem. please help if you can.
I have a SONY TV and silver Comcast remote.
Remote stops working on occasion and I need to turn the TV off to reset it which would make it work. Called Comcast today and now the remote doesn't work at all. They tried having me reset the remote, but it doesn't work.
Help? Thanks!
