Remove the 4 wires to the cartridge. With the system on. Put your finger on each of the wires separately. On two of the wires you should hear a buzz (one on each channel) on the others very little or perhaps a faint buzz.
If you hear the loud buzz(s) the amp inside the deck is working and you have either a faulty cartridge or have not connected the two wires right.
If you don't hear any buzz, the amp inside the unit is faulty. If the amp has other functions that do work (such as radio) then it is the pre-amp for the cartridge that has gone. As this will not affect the other functions.
Remove the wires to the cartridge (make a note of where they fit first). With your amp on, touch each wire (one at a time) with your finger. On one wire you should hear a buzz in the right channel, on another wire a buzz in the left. The two others should make hardly sound at all, or nothing. This test will prove the signal is getting to the amp. While testing make sure you move any RCA leads or plugs, to be certain they don't cut out.
If this checks out then replace the cartridge.
If it does not then you have a problem either with the connectors or and internal amp inside the turntable itself.
If you turn the unit on with no input and get a loud buzz, and when you put signal to it and you cannot hear the music but the buzz (Probably more like a hum). Then most likely the amp is blown.
Hello,the most common solution is to simply replace the subwoofer cable itself. the ground on this cable is the outside of the connector and not the pin in the center and they do fail. You can use any rca cable as a quick test to confirm if the cable is at fault.
try grounding the shield of the rca cables and see if the buzzing goes away. if so you have a bad ground to the rcas either in the deck or the amp. grounding the rca cable shield should take care of the problem.
Hello, you can verify that your receiver is working or not. When you are playing a dvd unplug the audio RCA plugs (red and white) from the back of the Sony dvd player. Touch the tips of each of the RCA plugs with your fingertip. You will hear a buzz sound coming from the speaker associated with the plug if the receiver is working\ i.e. touch the red RCA plug tip and the right speaker will hum...touch the white tip and the left speaker will hum or buzz. This will not hurt your system or speaker. If you do not hear the hum turn the volume to 3 or so and wet your fingertip and tap the tip of the RCA connectors. You will hear "pops" coming from the respected channel. I believe your cd\dvd is at fault. Good Luck!
Have you had any electrical work done to it recently?
... try two things. One, unplug the RCA cables from the amps to see if it is with the signal or with the amp itself.
Two, check the ground connections for them to be nice and clean as this may cause this issue.
If the buzz stops when unpluggin the RCA cables.. it's either a problem with the cables or with the Head unit sending this weird signal. (NOTE, if ALL speakers have the buzz it's mostly caused by the HU, thus, if it is only with one side as you explained, I'll lean towards a bad cable, or an amp failure (either not receiving proper ground, or it has gone bad.).
Hope this helps you some. if not, lemme know and I'll try to help you thoroughly.
Sounds like you have an open filter capacitor. Your gonna need to look at the b+ and figure out what cap is bad. A circuit diagram would assist you in this repair. If you have no experience with electronic repairs then your gonna need a pro to assist you with this as there are no user replaceable parts inside this unit. Sorry Man. Good Luck
