My bose remote for my lifestyle48 only works from really close up? I was lead to believe they work from any room in the house... what's wrong?

Look in the instruction manual and make sure that you have set the codes correctly, the house code for the remote, as well as the room code for the second room. Also check the batteries in the remote control, especially when the room as far away from the main room, the batteries need to be full in order to reach the center. I assume we talk about a wired system? When this is a wireless connection to the second room, it may need a reset, unplug and re-plug the wireless adapter, there should be a pilot light in the back of the wireless adapter, which should be green. If that does not help, call Bose.

Your v35 system needs to be programmed to work with the second zone wireless unit. Read the instruction manual how to do it, or let a Bose dealer set it up for you.

27+ is really quite old for electronics, a number of things could have gone but from your description i'm tempted to say the output chips have overheated or blown.... other things to consider with aged audio is the electrolytic capacitors drying out and also causing problems in the audio chain.

the fault is probably the infra red reciecer is low gain
this is normally a small printed circuit board.
best to let a service engineer replace it

Make sure you unplug your sa 2 and sa3 amplifiers after setting the codes. Wait at least 60 seconds, then plug back in. I would also unplug the in and out boselink cables as well. Once youve waited for a minute, then plug everything back in. Should work. If not, call Bose technical support. They are really great. I have 15 SA 3 amplifiers throughout my home. They are great.

Make cable guy get you one.I cant believe he left without fixing it.

check ur sensor if still cannot just go to repaired change onother new components

The first solution is wrong. (no offense to the Guru) This can not be caused by any settings, so save yourself the hassle.
The LS38 does use RF and IR, but if the remote works at all, RF is already active. 'IR control' is only for using other universal remotes on this system.
If shaking the remote does not cause a rattle, then there's probably nothing wrong with the remote. Also nothing wrong with any dip switches. (I'm assuming you've tried new batteries)
The power supply cable (DC power) at the back of the media center also doubles as the receiving antenna for the RF remote. Straighten this cable out as much as possible. Make sure it's not wrapped around any other cables, power cables especially. This should solve your problem.

It is a very strange case that you have.
I think that bose is correct, there is definetly an electromagnetic interference with the system, but the strabge part is that panasonic plasma tvs are not supposed to emit such EMI and they should be shielded.
one advice is that to verify this try putting on the tv, and bring a portable radio close to it and see is there is a change in the sound, if there is one, then definetly your tv is emitting EM fields. this could be due to a factory defect in the tv, have it checked by the retailer where you got your tv.
a second solution is to place the receiver of the bose system further away from the tv and try using both of them.

Have you tried using the remote antenna supplied with the Bose system? This connects to the "Remote antenna" socket on the rear of the media centre and is made up of 2 parts: a shielded section (black in colour) that runs past any sources of interference - mains or signal cables, other electronics products - and the unshielded antenna (clear plastic covered copper wire) that must be fully extended vertically to act as an aerial. Position this away from sources of interference and as close to the second room as possible (Bose do a longer version, free of charge in some countries....)
The remotes only have a range of up to 20metres - this will drop the more walls it passes through and the thicker the walls. Any interference can affect this - radio transmitting equipment (WiFi, video sender, but especially products transmitting on the same frequency - 27MHz or 40MHz, e.g wirless thermostats or alarm systems....) or products with poorly shielded transformers. Experiment with swtiching off other electical equipment (including lights if they have a transformer - e.g. halogen spot lamps). If you identify a source, can you move it away.....?
