I have a Lifestyle AV38. I bought it second hand without a remote.
Since then I purchased on of those universal remotes that was supposed to be preprogrammed, but no joy.
So I purchased a proper second hand BOSE remote for my system. It is an RC38T1-27.
All 8 dipswitches in the battery compartment are switch to the down position (pushed down towards the bottom of the remote control).
New batteries, no luck. Tried reprogramming by holding ENTER while it's off and pushing some buttons, not luck. Note when I hold ENTER when it's off, the HOUSE CODE appears with 4 blocks in the bottom position I believe.
I thought it might be the IR sensor, so I ordered a replacement. I'm handy with electronic bits and was able to replace the old one myself. Then plugged it back in, went through the steps above and still no luck.
I then tried the universal remote and that doesn't work either.
I suppose one possibility I can think of is something wrong with the motherboard or pins for the IR sensor plug.
Any suggestions on what I can try next?
