Picture quality is dim. There's also a continuous crackling sound emanating from the rear area, I believe in the area where the lamp goes. Is this merely a lamp problem?


check the lamp ballast board which may the cause of dim and crackling sound. check for bad high voltage transformer and dry joints connector at the ballast board.

Crackles even after blades are cleaned


To stop the crackling sound, you need to remove all of the dust particles from the wire in the back. Sometimes when the unit is extremely dirty you can see sparks emanating from the wire, this is what causes the crackling sound. The unit has a built in cleaner you can lift up and down to perform this task, located on the top, but this doesn't work extremely well.

I usually take a can of compressed air and blow as much of the dust I can off the wire and all surrounding internal areas as I can. To do this, approach the unit from the front, and turn the blade door slightly so the wire can be seen. This along with a thorough cleaning of the blades should eliminate the crackling noise. Of course, make sure the device is unplugged before performing any cleaning.

My bass makes a crackling noise it never used to have this problem, i put this little faggy magnet near it and i think its the cause


Sounds like you turned your system up beyond it's capabilities... aka blown woofer. Buy a new sound system from www.pcrepairshop.org and that crackling noise will be gone for good, guaranteed!

My Aiwa powererd sub-woofer TS-W50U) has crackling sound.


Crackling is an unusual noise but typically indicates a bad capacitor in the amplifier board. This can be a rather costly repair but first we will go through basic trouble shooting steps.

Reduce the volume on the sub and see if the noise remains and changes with the volume.

Unplug the sub and disconnect interconnect cables. With both hands push softly on the speaker cone to move it in, let it back out and do this a few times. If you hear a scraping noise and some resistance your driver is misaligned and you need to recone or replace the driver.

Check all your interconnect cables, there may be a bad internal connection (usually causes pops and cut-outs).

Let me know how things workout. If it makes the crackling noise at all volumes and the driver seems fine then I would seek a professional to repair it, or replace.

Cheers,

Kevin

Not sure about the smell though. Mine has started to smell a little strange and I haven't figured out how to fix that problem.

M-Audio BX8 blows a fuse


If your monitor is crackling and fizzing, that is not a fuse issue, unless the fuse you have installed is underrated. It sounds like you have a bad driver/woofer, and need to get it replaced. CLICK HERE FOR THE REPLACEMENT DRIVER for this model.

Crackling Sound From Subwoofer


Check any wiring coming or going to the subwoofer. It sounds like it could be a loose connection.  Is there a LFE or bass boost knob on your subwoofer? Does turning that up/down cause the crackling (if it exists). If so, you could use some tuner cleaner to clean the contacts on the potentiometer knob.

If the crackling is on the subwoofer only, it might be damaged from bottoming out.  See if you can remove the baffle or grille covering the woofer and inspect for visual problems. You can also try to lighly push in and out on the subwoofer to hear if it makes any scraping sounds. If so, it is definitely damaged and the driver will have to be replaced.
