Hi there, new guy joining the club here... been using Altec speaker since about 10 years back. Below are the list of Speaker that I owna and still kickin'.
ACS45.1
321
BXR1121
FX3021
One thing i'm not understand and need all the sifus here to give me some advise.
The FX3021 i just bought it during the recent PC Fair. Sounds is good but unfortunately the left speaker is making cracking sound, either during watching movie or listening to music. It's connected to my TV. Soemtimes it won't come out some times you'll hear that very obvious but it won't "crack" very long though.
Any advise on this?

Oh thanks.. hm.. thought of using some cotton to clean directly like that. Spray on the cotton and poke into the hole. Let's see is there any dirt coming out from the jack...

QUOTE(power911 @ Sep 1 2010, 02:57 PM) spray directly(but not ridiculous amount... think logic) and clean it up with cotton bud? don't worry,it won't short out your tv that easily give it some time for wd-40 to settle and dissolve the crap then wipe it off... maybe like a minute or two when you clean it out it should come out dirty Hi, i try with the WD-40 thingy yesterday but it seems not working and there's no "dirt" or any dirty thing on the cotton. I guees it might not be the problem as my TV is less than 4 months old. I even us the WD-40 to clean the mini jack head. still no luck. When i play any songs or anything, the left speaker sound is just like a little breaking compare to the right speaker which sounds solid and no such "breaking sound"... anymore suggestion sifus? Need to send back for RMA? |

not totally distortion though, is like the audio is not clear, quite difficult to explain as my audio knowledge/words is limited here.
It sounds a bit of "plak-plak" when it comes to certain high tune whereas the right speaker sounds just find.
Another thing i notice is both speaker will have this hissing sound.. anyway to elimitate tha?

QUOTE(beggarmaster2000 @ Sep 4 2010, 11:32 PM) hey guys =) have you tried plugging it into another source? it might be your tv for all you know? my guess is.... if it comes from pc fair it should be old stock or slightly defective product my best guess is that 1 or more (plik plak suond)signal path capacitor is dead, hissing sound most likely come from power filter cap, so changing/upgrading it will be a good idea... dry solder might also be present in such situation if i wouldn't ask for help here if i am no good with a solder and don't know how to pull your set apart... and most importantly we all need pictures of the insides before guess work =) try your warranty first before attempting to cure it yourself unless you super confident =) Well, as I mentioned, i tried with MP3 player too also the left speaker sound is not "solid" as right speaker. Anyway, will try to arrange to send for RMA then... but before that need to find a song/some audio that will trigger the plik plak sound again when they asked for that. haha.. |
