Question about Audio Players & Recorders
My bose lifestyles 20 system powers on fine then the sound will cut off after about 5 minutes. If I turn the power off then back on the system will cut the sound off after about 5 to 10 seconds. If I turn the power off and let it set for about 15 to 20 minutes before powering it back on it will again stay on for about 5 minutes then cut the sound off. I think the system is overheating but not sure where to start (head unit or base amp) or what to do or check for. Any assistance in this matter would be appreciated. Thanks for any help.
It sounds like the digital signalling processing chip has bomed out, (assuming it is the digital version, this can be verified by the 9 pin connector on the bassbox beside where the speakers are plugged in) perhaps it has recieved some un freindly electromagentic interference.
if this is so, i'm afraid there is no way you can fix it or reprogram the EEPROM (well of course there is but even if you had the correct equipment you need the program)
I would be supremely confident that BOSE could quiclik fix that for you with little difficulty, the neaserst dealer probably has the correct programming cabling and equipment.
if its not the digiatal version or even if it is, there is a second potential problem,
either the CD head unit or the powered bassbox is tripping out due to either circuit overheating or electrical fault,
in either case ? that is difficult to rectify, as the highest likely hood is the baords are covered in dust taht could be conducting static or a fault has developed.
the bassbox could be opened, but you might damage the cover (leave this as a last resort, especially if you havent done that before!) so bring a broken cover to the dealer will be a bit embarrasing ;-(
worse a broken cover will rattle when reinstalled and working again and will result in starnge sounds too.
honestly, seeing as i'm recommending taking to the delaer anywya, try aand bring cd unit and bassbox back to dealer a quick test by swopping modules will quickly eliminate or find the source of the problem, alternatively try doing the swop test with a similar unit around at your friends house !
hope this helps.
