Question about Sony Audio Players & Recorders
I have a phono preamp connected to my sony cmt cp100 in order to use my turntable, but i recently noticed a random deep growling noise coming from the speakers when the preamp is on. It happens super randomly, once every few minutes. I can't wrap my head around what it could be. Is there some sort of "incompatibilty" between the cmtcp 100 and the preamp? I switched cables, loudspeakers, and even replaced the preamp but the darn noise is still there! any clues? thanx in advance!
Hi Humberto, comment the brand and model of the phono preamplifier, also if it has a separate power supply or inside the preamplifier cabinet
I ask you this, because if you were armed in a plastic cabinet, you could pick up interference caused by cell phones or other type of component that can emit electrical noise and these interferences are those that could generate the noises that you hear in your speakers at the moment that you listen to the discs
I await your comment
Greetings Franco Dosil
Hola Humberto, comenta la marca y modelo del pre amplificador de fono, tambi?n si tiene fuente de alimentaci?n separada o dentro del gabinete del pre amplificador
Te pregunto esto, porque si estuviera armado en un gabinete pl?stico, se podr?an captar interferencia que producen los tel?fonos celulares u otro tipo de componente que pueda emitir ruidos el?ctricos y estas interferencias son las que podr?an generar los ruidos que escuchas en tus parlantes en el momento que escuchas los discos
Espero tu comentario
Saludos Franco Dosil

Testimonial: "Hey Franco thanks for your message! I was using this LD PPA2 preamp when I noticed that weird noise. The preamp has an external charger. https://www.uraltone.com/hi-fi/etuvahvistimet-riaa-korjaimet/ld-systems-ppa-2-riaa-etuvahvistin.html Then I replaced it with this TCC-750, which is in fact better and more expensive, but it keeps making the same noise! This preamp also has an external charger. https://www.uraltone.com/tcc-tc-750-hifi-riaa-preamp.html The turntable is a Yamaha P-350. The noise is not a hum but more of a short, low, kind of growl (for lack of better words). It happens intermittently, only once every few minutes. Very randomly. Super weird but very annoying too! I appreciate the help. Thanks!!"

SOURCE: Memory Loss
Many devices utilize a small battery for system memory purposes, such as radio station presets. It draws a small continuous current for that purpose. If your system used to keep the presets when disconnected, then I would guess that?s the case. Search for a small battery compartment in the back of the system, take out the battery and take it with you to be replaced with one just like it. If that doesn't fix it, then i hope you're still under warranty, otherwise either you'll have to live with it or take it to a repair shop. Good luck!

It sounds to me like you both are having a problem with a capacitor going bad. some capacitors act as a noise filter and it sounds like you both have a bad one. If you are any good with a volt-ohm meter that reads capacitors you should check them to make sure they are at their proper values which will be posted on the capacitor. then replace it. if you dont know how to use a v-o meter then take it to a shop and have them replace it

HI. that grinding sound is signaling a lens assembly issue. the linkage and gear assembly seems to be jammed. this assembly must be able to move freely i order for the lens to track the CD. if the lens assembly is stripped or jammed, it will not be able to read and it will shutdown into stand by mode to prevent the motor from damaging itself. its most likely gear failure.
Unfortunately, the repair parts for this unit are only available from sony repair depots and, you will need to contact sony manufacturing in order to receive a repair ticket.

I have not found a way to select Audio
In without the remote (and I've tried every combination of buttons I can think of!)
The approved way to select Audio In is to press the FUNCTION button on the RM-SC30 remote that should have been included with your Sony CMT-NEZ3. See http://esupport.sony.com/US/perl/model-home.pl?mdl=CMTNEZ3 to download your manual.
