LOL. This is a common, easily solveable problem. Remove your cellphone or anything that emits radiation of any sort from the general area. Don't believe me? send a text message while sitting net to your speakers. It does this even if you arent sending a message because your phone sends intermittent signals to the cell tower. the radiation being emitted from the phone does weird things with the magnets inside the speakers.

Sony stacking system LBTd505, the sound from the record deck suddenly went very faint. The cd and radio sections are fine. I have tried a new stylus, but no difference. Any ideas?


You have two options. First a faulty cartridge. Or a faulty pre-amp in the main amp.
You can find out if the cartridge (and amp) are playing up. By removing the connectors on the cartridge.
Then with the volume turned up to about half, with your finger, touch each one of the wires one at a time. It will not harm you at all. But you should hear a loud buzz on one wire on the right and a loud buzz on the left on another wire.
The two other wires will either produce a crackle, or a tiny buzz, or nothing at all.
If you do hear a loud buzz on two wires. The cartridge is faulty and needs replacing.
If you hear a slight buzz on them or weak sound. There is either a bad connection between the deck and amp. Or the pre-amp inside the deck which is only used by the record deck so will not effect any other function, is faulty.
You can remove the record deck connections to the amp and again with the amp on half full, touch the inputs with your finger. If you are not hearing a loud hum or buzz, the pre-amp is faulty. If you do the connectors are faulty.

Klh powered subwoofer model ASW10-120B... when you plug in to power... it makes a loud buzzing/humming noise


I would check the caps on the power supply. They are rather large electrolytic capacitors that will look like they burst and/or leaking. When these die, the caps ground and the sub will make a loud buzzing sound. If you are handy with a soldering iron you can replace them yourself. Replace them with the same voltage or a little bigger and same with the size.

If the cap. says 16v 4700pF on it, for example, a 20v 5300pF or a 16v 6200mF cap. will work for this application.

I get a loud intermitant buzz from one of my JBL eon 15-G2 speaker, no music signal just buzz. What is the problem do you think...? EQ circuit problem, speaker cones seem to be intact.


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.

You have two issues here, one is that your CD ROM lens is dieing slowly but, you can fix temporarily by cleaning this lens with a CD lens cleaner. secondly, the power supply side on the main board is starting to malfunction and may be on its way out. that is what humming/buzzing sound you are hearing during play. hope that helps ya and, thx for using fixya:)

Sounds like the amp has developed a problem. If you had it LOUD then you may have popped a speaker or an output stage. You say it still makes the plugging in noise, what happens when you touch the end of the jack lead whilst plugged into the amp. do you get a burst of clean hum?
