You need to verify if the remote is sending out the IR signals or not first.
Testing remote control:
The remote control puts out IR (InfraRed) signal that human eyes cannot see, to find out if the remote is sending out the signal or not you just point the remote at the digital camera's Lens (Digital Camera can detect IR), you should see flashing light on the camera's screen when any one of the remote button is pushed. If you do see the flashing on the camera, then the problem is in the TV IR receiver or the main logic board; more troubleshooting with scope will be needed to look at the signals.
If the remote checked out OK, then look at the back of the TV first for the "REMOTE INPUT", use a mini-phone plug and insert the plug into the remote input jack in and out a couple times to clean the switch contacts that select between the front IR receiver of the TV or the rear panel IR input jacks.

You need to use the IR emitter that came with the Bose V30 system. Bose employs a proprietary RF frequency remote which communicates to the hidden central control head. You plug in the emitter to the processor unit and run the emitters to the IR 'eye's' of the equipment you want to control. Once all this is done then and only then can you go through the remote codes to control a particular device. The Bose V30 has 2 IR emitters that come with the unit to control 2 devices. You can expand on that buy buying a IR emitter bridge that has several inputs for other devices.

Now when it comes to a DVR I am not so sure the Bose universal remote will work all the playback and FF and record control buttons and a DVD or VCR. I hear there is a new BOSE remote on the market that can do that but I have yet to see it in person or ask a sales rep about it. Sometimes they are non-tech's so its no help : (

Check manual, but i think you need it to navigate numbers

These are the codes for Sanyo TV'S for this remote. The newer TV codes are at the end so work in reverse order when inputting these codes. Thanks for using Fix Ya.

Best chance is linked below but you will need the remote's model/part number at hand since the site couldn't find that model number:
