You can re-calibrate the remote first by following the steps below:

2. After a few seconds the word CAL will appear in the middle and the word SOURCE will appear in the top left area of the remote.
3. Press the SOURCE button.
4. The word KEYPAD will appear in the top right area of the remote
5. Press the KEYPAD button and a small circle will appear in the bottom right of the remote.
6. Press the Circle
This should've recalibrated the remote.
If you need to relink the remote to the system, HOLD down the mute button while having the remote as close as possible to the unit. You will hear a beep . Release the button, after a pause , you will hear the remote beep twice.
This re-links the remote to your system
If the backlight is not working, your options are
1. Spend $349 and get a new one from Bose Or
2.Spend $220 and get a used one on E-bayOR
3. Use your remote with the lights on so that you can see the display :-)...the cheapest way OR Invest in an LED Book light that you can clamp on the remote and use that for your light ($9.99)

@ajcooke01 · can’t give up on iFixit. Of course you tried the reset: · Unplug the multi-room interface power pack for a few seconds, then reconnect it. This allows the unit to reset itself after a power surge or power interruption. · and you tried to re-establish a connection: · If NO RESPONSE is continuously displayed, the link between your music center and the multi-room interface may be broken. To re-establish the link, hold the center close to the interface. Press and hold MUTE for about 5 seconds until you hear a second beep. After about 10 seconds, you should hear two beeps to confirm that the link is established. · Note: The music center establishes a link with the closest multi-room interface. · If you have the multiroom interface you could try to control it through a computer interface. Looks like the Bose Lifestyle all use the same serial commands: · COMMANDS:Setup....\x54\x41\x50\x0D · ON/OFF....\x61\x45\x40\x40 · Vol Up....\x61\x45\x41\x41 · Skip Reverse....\x61\x45\x42\x42 · Play / Pause....\x61\x45\x43\x43 · Skip Forward....\x61\x45\x44\x44 · Vol Down....\x61\x45\x45\x45 · NextDisc....\x61\x45\x46\x46 · Video 1....\x61\x45\x47\x47 · Video 2....\x61\x45\x48\x48 · Aux....\x61\x45\x49\x49 · CD....\x61\x45\x4A\x4A · AM/FM....\x61\x45\x4B\x4B · Tape....\x61\x45\x4C\x4C · Stop....\x61\x45\x4D\x4D · Mute....\x61\x45\x4E\x4E · Mute All....\x61\x45\x4F\x4F · Random....\x61\x45\x50\x50 · Play....\x61\x45\x60\x60 · Pause....\x61\x45\x61\x61 · Fast Rev....\x61\x45\x62\x62 · Fast Fwd....\x61\x45\x63\x63 · Zone 1....\x61\x41\x01\x01 · Zone 2....\x61\x41\x02\x02 · If nothing, else this should work for you for more troubleshooting. 199402
