Question about Bose Lifestyle 30 System

1 Answer

Slow decline in volume

My LF 30 volume slowly declines for now reason, I turn up the volume to compensate until I cannot turn it up anymore.

The only way to repair is to power off and power on the system.

I just watched a 2 hour movie, had to reset 3x.

Thanks

I'm a bit of a bose LS 30 expert myself, very closely involved with bose lifestayle reanges professionally for many years.
thers a problem on the amp module on the back of the bassbox or a problem with the CD 20 volume output being reduced over time or lastly and quite simply the remote is fualty.

in each case the problem is easy to track down.
1st. take batteries out of remote ( and any other bose remotes that may control the cd 20, ) if the problem goes, get a new remote, impossible to fix unless its obvious mechanical damege to remote.

2nd get a loaner from somebody else or the shop of either cd 20 or bassbox, ( it doesnt really matter for the purpose of the test which nor which bassbox you try, it dosent have to be perfectly acoustically matched to see if the sound is dropping., once the cables match up. ) this will eliminate the possible probelm in either remaing unit.

as far as repair is concerned. you could have a go if you wanted to mess around witha lot of baord level electronics, but once youve identified the cause of the problem i suggest get a bose authorised repair or buy a spare one second hand. ( you'll only need the faulty part complet and in tact)

whatever you do.......... don't open the bassbox, as its a few years old the chances are you'll not be able to seal it back up properly in a way that will rerproduce the same quality of sound. and even if the bassbox is not at fault you'll probably have to suffer an ugly looking repair or a new bassbox that isnt necessary.
if on the other hand if you are determined to open the bassbox, let me know and i will help you do it properly but the chances are there is nothing there causing the volume to fall, that can be repaired without building a complete replacement and lots of visits to radioshack or your local electronics shop, and i would be extremely amazed if the problem is in the bassbox.

i would bet you have a faulty remote or at worst a control voltage problem in the CD20 unit.

RT2770 cuts out above a volume setting of 30.


Bass and other settings may be set too high and are overdriving the unit.

If all else fails try the old unplug it for a while and then plug back to see if that helps.

What if anything else is hooked up at the same time to this system?

Hello, I have an RT 2870 RCA surround sound system. When I turn it on all I hear is static and its not until I crank the volume up to around 25-30 before I can hear the audio. How would I fix this problem?


NEVER USE MAXIMUM VOLUME FOR TROUBLESHOOTING.

Turn the volume control to something medium.

The errant switch, control or condition may change and you will suddenly release the amp's full power and possibly destroying your speakers. If a signal isn't audible at 1/2 volume it's probably not there.

Carefully examine the front panel for clues like a misplaced Mute or Tape Monitor control or Multichannel Analog Input selected.

There is a good chance that a common control (volume pot??) may have developed a high-resistance or 'dead' spot through defect or idleness and is causing your symptom. Turn the POWER OFF and operate every control throughout its range a number of times, especially rarely-used ones like Tape Monitors and the Mute control.

Turn the volume to something reasonable and see if that helped.

My SC BT100 is perfect until I use the IPOD dock, it works ok for 10mins but then 'blows'. the unit becomes very hot and wont turn back on until it has cooled down.


You are overpowering the Amplifier and it is protecting itself until it cools down.

The reason for this is that the output from the IPOD is already pre-amplified. If it didn't shut down you would either blow the Amplifier or Speakers.

If you keep the volume turned down to a minimum on your IPOD and use the volume control on your theater system you should be OK but still don't turn the theater system to full output.


Please leave feedback.

Cheers

Sounds cuts out if volume is over 30


hey
I have been has same problem for long time, actually problem was on and off... the reason was short circuit of speakers or speaker connections.

I find a little peace of cable stack inside of the connection handle. you know all the cable stick on back...

well what you can do is, unscrew all the screw back and the bottom of the box. slice the electronic box, just check connection piece is clean cable free....

use always clean cable and don't put it too much.

it is very easy to fix

Volume increases on its own intermittently


When the volume increased did the display show it doing so as if someone was turning the knob?  I mean did the volume go from like level 15 to 30 or did the unit's level stay constant while the audio volume increased?
Were you alone or sharing the room with a jokester who has a universal remote?
Does this problem occur when the batteries are removed from your remote?
Are you sure the 'volume up' button on the unit itself is disengaging properly after being pressed?

Volume Does what It wants


My Yahoo YHT-400 does something similar, only it won't do it right away, it has to start getting hot first, then if I have the volume set at 25 or higher, it will slowly start turning itself up louder until it either maxes out, or I intervene. Either way, it's really annoying, even though I'm only using it as an amplifier for my computer. I just figured it was doing it where it's second-hand and had tons of dust inside caked in and around the fans until I cleaned it out. But when on AUX/TV, one would think the Bit Rate Transfer gauge would remain at 00, but it jumps up and down constantly, whether there's any audio being put through it or not.

Whine


i have a koss KS4102 system also and mine does the same thing. its done it for almost 2 yrs now. ive taken it apart and noticed that the sound is coming from under the heat sink. im not an expert at home audio, but my best guess is its either the amplifier going out, or some kind of processor. but i do know from past experience that its probably going to be cheaper to buy a new receiver, rather than paying a pro to fix it, if it can be.
