Cold solder issues - each component is soldered into small holes on the printed circuit board which in turn connects said component to the other components. Due to time, heat, use, some solder joints would be cracked or loose. It is possible that the cold solder is still minimally connected (hanging by a thread). When the receiver turns on heat would be generated which would be sufficient to further loosen up the solder joint to the point it no longer provides electrical contact. Jarring the unit creates movement inside enough to re establish the contact, sometime good enough sometimes not enough.

Again, since the unit still operates (sometimes) then it is highly probable that there are no defective components. As you have surmised, it is possibly a loose connection, solder joints are "connections" except that molten soldering lead is used to attach/connect the component to the board, "loose connection" in this sense is equal to "cold solder".

Again on the assumption of no defective parts, then seeking a more experienced buddy for the soldering might be to your advantage. This is of course in addition to the possible electrical hazards when repairing....If this solution help you understand the problem :rate as fixya..

Good luck;

MX6050D Subwoofer Issues


Hello, welcome to Fixya!

Fault is either from the main system or the sub-woofer itself.

You need to test both unit in order to detect which of the two is giving the fault, so that you can concentrate on the faulty unit.

Test the woofer with a AA battery or any other battery. Put your ears close to the woofer and observe if you will hear any sound. If the woofer makes sound, then it means the woofer is working, but if it doesn't make sound, then it means the woofer is defective. Or you can disconnect one of the working speakers and connect the woofer to that part. If there is no sound, then obviously, the woofer is defective.

If the woofer seem to be working, then the unit needs to be tested also.

Connect one of the working speakers to the sub-woofer's section of the main unit. If the speaker doesn't bring out sound, check the system's menu settings, check the volume and make sure the sub-woofer volume is raised to the highest level and not on mute. ( Note that most Theater systems has separate volumes for each speakers). If the volume is raised to the highest level and there is still not sound from the woofer part, then it means the woofer channel has burnt. It could be a fuse or a defective channel. At this point, I think you need help from a repairman.

I hope the above is clear.

Regards.

My infinity overture 3 crossover does not work anymore (both sides of the crossover do not have any output. If I bypass it the speakers do work (obviously without the filtering) My question is how do I...


This is a 3-way speaker; specifically which speakers do you hear something from and which speakers do you hear nothing from? If the woofer amplifer is blown, for example, you will hear nothing from the woofers, but will hear sound from the midrange speakers and the tweeter.

My sub make a strange noise. It doesen't work anymore.Tks.


Strange noises can come from your amplifier or the sub itself. The most likely cause of the strange noise is the speaker just before it dies! If you have been using the sub-woofer at high volume levels then you probably have damaged it. Try testing the sub-woofer using a multimeter(on ohms setting) it should give you a reading from 8 to 4 ohms. Sometimes they may give readings as low as 1 ohm. When testing the speaker/sub you should hear a soft scratchy, thumping or clicking sound. This indicates that the speaker may still be working. If you don't have a multimeter try a 1.5 volt battery (say a AA), DONT USE HIGHER VOLTAGE BATTERIES they may damage the speaker! You will hear a clicking, scratching etc sound from the speaker which may indicate that it is still OK. If the speaker seems OK the problem may be in the amplifier, which I suggest you bring to a professional repairer. When buying speakers and amplifiers make sure the power handling of the speaker is equal to or greater than the amplifier output power. This should stop speakers from getting damaged. Make sure the speaker and amplifier specifications are rated in the same manner ie RMS PMPO Peak. A 100 Watt PMPO speaker will not survive the output of a 100Watt RMS amplifier!

My sub woofer stopped working, please tell me where it is located so i can check the speaker and also check if power is going to it thank you very much joe


The JBL premium sound system has a large woofer in the bottom of each door, a small mid-range speaker next to the woofer, & tweeters next to the front door windows in the corner, & two full-range speakers near the rear seats. The woofer (not sub-woofer) handles all the low end. You can test the woofer by turning the BASS to max and TREBLE to minimum (make sure balance and fader are centered) and put your ear next to each woofer.
The woofer is usually the 1st speaker to have problems after 10 years or so. The outer edge of the woofer starts to degrade. You will usually hear a rattling sound out of the woofer when this happens.
NOTE: If no sound at all out of the woofer (tweeters are OK), you might take your car into a car stereo shop. They can put a speaker on the wires connected to the speaker and make sure your problem is not the radio.
PROBLEM: You can still hear sound out of the woofers but it is distorted
SOLUTION 1: Go to a car audio shop and have them install new woofers. These may cost $30+ each but the dealer cost is over $200 for each woofer (crazy).
SOLUTION 2: More involved but very cost effective. If you or a friend is handy, you can go to www.speakerworks.com and order a new set of speaker outer rings (on the site they are called speaker SURROUND) that will replace the damaged outer rings on the woofers (replace on both woofers). They really work great and your speakers should last for many more years.
Hope this helps.

Static noise in Yamaha HS50 monitor


Sounds like the voice coil is damaged on the woofer. If you GENTLY press in on the woofer cone, and release, you should not hear any scratching noise. If you hear noise, the woofer needs replacement.

I hear some noise coming out from the woofer of CHT-12R


It very well could be the spaker leads hitting the speaker cone.

You could check this by removing the amp section from the back.
Remove the screws at the very edge of the amp panel.

I have a pair of mackie srm 450 and one swa 1501 the bass output in one of the 450s has no sound. i hear sound only from the high frequency part of the speaker


you have one of two problems.1) the woofer is blown(most likely) or 2) the crossover is fried(rare). Take the woofer out and press on the speaker cone(softly). If there is a scratchy feeling when you move it or if it doesn't move at all, you'll either need a new woofer, or get that one reconed.
good luck.
