Question about JVC RX-6042 Receiver

1 Answer

Sound cut-out Sound from any source, DVD,CD or even VHS cuts out at irregular intervals, sometimes 5 mins apart, sometimes 20 secs. When it cuts out it might stay out for 3 secs or sometimes 30 secs. I have Digital optical in as well as RCA's to R & L (red & white).I have checked all connections, changed the optical cable and even changed the DVD/CD player. Any ideas? Cheers, John

    I have this same problem. I have chacked all DC voltage, protection circuit, all transistors in voltage stabilizatin circuit +12V -12V +5V and everything look good. I think problem is with some temperature protection, but I don`t know where I should to find it.

    I have the same problem. When the sound cuts out, the receiver is switching to pcm mode. Is there a way to do a factory reset on this machine. Couldn't find it in the manual

Most likely this unit goes into protect mode due to heat detection. Try to see if there is a pattern to when this behavior starts. Does a lower volume level allow the unit to run longer? Perhaps there is a problem internally that is allowing DC voltage to get to the output stage. This will cause excessive heat which can then cause the protection circuit to kick in. This unit may need to see a bench with some test gear to locate the exact problem. If you can, look for any pattern and update this.

The VCR is not turning the TV power off. The tape is not playing. I'd guess maybe it needs a cleaning or a replacment.

Sound cuts out from time to time


Hi, your system has some problem on the bass module which overheats the thermal sensors built in the bass module/subwoofer. I recommend that you bring the bass module to the Bose service center near your location.

That is the only solution...

Speakers crackle, then sporadically stop


Sounds like an amplifer fault. Many of these Midi system use a large black IC attached to a metal heatsink. They control both the power amp and pre amp on both channels. When they go wrong they can cause all sorts of effects,
If you can repair things I would look at that. If not get ready for a large bill. If it's the IC some are expensive, it does most of the work!

Bose lifestyle 20 sound cuts off


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.

NAD C541i CD Player plays but the sound cuts out for an instant every 10-20 secs. It eventually goes away, but it is annoying when you first play a disc. Any help appreciated.


hi, i've had a few nad C541i's and not so long since the sound on one of them cut out for milliseconds and on some occasions the sound would make the noise very much like a severely scratched vinyl record, i thought it was a faulty laser so i tried another KSS-213C laser out of a scrap kenwood and the fault persisted. to cut a long story short, i took the main PCB out and there were various dry joints. once these were resoldered i was blessed with a fully functioning player. hope this helps?

Freezer problem


Not sure of what cut out refers to. If you mean the power supply is tripped out after twenty secs hen I would say there is a fair chance of the compressor being down to earth (ie broken). If you mean that the compressor tries to run and then stops after twenty secs then there is a fair chance the compressor is stalled (ie broken). There is also a chance that the relay (starting device) may be at fault failing to start the compressor. If it is the relay then the cost may be around £70 if its the compressor then you are lookin at a couple of hundred pounds approx. The buzzing sound does sound like the compressor trying to run but stalled and unfortunately compressors have no real average anymore and are prone to fail whenever they choose to. Sorry to sound negative and hope this helps.
