What is the remote code for comcast grey button remote for SONY STR DE835?

Check the circuit going to str-de835 probably there is an open resistor leak of diode check one by one.

If you wish to get more details, check this site. Pull up previous posts there. Setup code list and setup proceedings to many popular brand remote controls are given.

Code 31518 should work on your Comcast universal remote here is a link good luck! http://www.comcast.com/MediaLibrary/1/1/Customers/Customer_Support/Digital_Cable_with_OD/Digital_Cable/remotes/Remote_M1067BX3.pdf

If you consult the card that came with the remote, you will find several codes for "Sony". You will need to experiment with each code until you find one that will power the receiver on and off. Then you will have control of the receiver. If you don't have the card, then go to the web site and download a copy in PDF format from there. I have a lot of Sony stuff, and I have found that the codes varry according to the year the equipment was made and its function.

Theres a couple of problems you may have. 1 bad solder connections,you can remove bottom plate and look for bad connections and 2 you may have shorted transistors, however if the protect relay comes on its probly bad connections.

Most likely bad output transistors and a couple of resistors. mp1620 and mn2488 are the part #s for the transistors. If you take it to a repair shop you are looking at spending $100-$130

First you need the Comcast Remote with a grey OK/Select button in the middle. Program code 1903 and it should work. I have a DAV-FR8 system and it works. Was unable to get the remote with the Red OK/Select button to work.

First you need a Comcast remote with the center button, OK/Select to be grey. Now program in code 1903 to aux. Works on my FR8 System, same basic as FR9. I was unable to get Comcast remote with red center, OK/Select, to work with any codes.

I found the operating instructions here:

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:
Vol+ = 32975
Vol- = 31951
Power = 32719
Good luck. Let me know if it works.
