High pitch screech

try lowering your ringer volume or reset your phone.

Some things I would check are do you have blue tooth in operation. Do you have any form of michrophone in the cab as it sounds like a feed back problem coming through your speakers. Talk to a radio techie to see what he thinks

It most likely is coming (based on model number listed here) from the high voltage transformer---ways to silence that up to and including replacing that part.

i dont know how to say it dude but its something inside the ps3 i dont know what its called but yours is probably burned or broken u can get it fixed for about 50 dollars if u have warranty on it or call sony and u can send it to them

Does the ringing happen when listening to the radio, CD, or both?

that high pitched ringing is usually caused by a power leak in the high voltage section of the set. it needs to be looked at by a proffessional electronic technician before it goes out altogether.

That high pitched ringing sound is a faulty colourwheel that will need replacement.

Okay for starters, you need to check to see if that fax machine is automatically answering the phone when it rings. you can check to see if it is trying to recieve by call that phone number from another phone and listen if it answers and when it does, does it make a high pitched squelling sound that varies in pitch.
if it does then it should be working ok, if not then you must program your recieve mode to automatically answer.
you can also check to see if it's sending by doing the opposite: put a sheet of paper in the machine to fax and dial your cell phone or other number, when it rings pick it up and listen for the high pitch squeel, if it works then your fax is working properly.

Thank You,

Sounds like the capacitor that goes bad just before the hIgh Voltage transformer goues bad. If i were you I would call an authorized RCA repair Shope and see if this is going to cause more damage to your set in the future.
