Thank you I have been trying to use various remotes and even purchase Harmony remote, another remote on my home theater PC and had called Comcast support a couple of times (over a year ago) but today I found your post and followed the instructions and it worked like a charm for my SONY DAV FX-500 Home Theater System. - Thank you!
And found a bunch more codes that seem to be working (most of the 'Sony15' ones that I've tried seem to be working - this is awesome). I pulled this from the following link (may be easier to read there)
I used to have a 'Function' code which was VERY handy (I lost my original remote, just ordered a new one off ebay for $7.50 from China, free shipping), hoping to find that code again. Anyone? If I find it, I'll post it here.
Comcast is of no help with this. I called customer service and was told to call Sony. I found a posting on a blog (not Comcast's) that worked for me, and I hope it will for you you here it is:
Re: Comcast remote code for Sony DVD home theatre
I finally found a way to control a Sony DVD receiver amplifier combo with the comcast remote. Mine is model DAV-DX150. I'm so excited about it I had to create a user name here just to help the other poor souls juggling multiple remotes. I found this answer on fixya posted by rmgillsp. Don't know who he is but I love him this worked for me:
It seems like most (maybe all) Sony HTIB do not work with the Comcast Custom Remote. I've found a work around that fixes the volume control and power button though. Hope it helps you all. I have a DAVHDX275 but I think this will work for most Sony HTIB systems.
What you need to do is steal some codes from a like product and then hardcode in the changes you need to the comcast remote. Set your AUX to 21232 (a Sony code for TV/VCRs).
Then do the following:
1. While still on AUX, press and hold SETUP again until the remote blinks twice
2. Type 994
3. Press and release SETUP
4. Type 32975
5. Press and release VOL+
The remote should blink twice. That should reprogram the VOL+ to work with your Sony HT device. For each of the following function codes, follow the same steps and use the codes listed below:
Is there a code for the silver remote with red button to control my Sony DVD home theatre system? I had to exchange my remote with the grey button because it stopped working and i received the red button in exchage. I could control it with the previous remote but I have tried all of the codes for all sony devices and the search for code feature but no luck. The model number for my unit is DAV-FX500
