its probably the sensors inside your phone. most manufacturer uses magnet or sensing... if you can open your phone check if its still in place... if not visit your service center...

SOURCE: Subwoofer just stopped working. There's power but no sound.

I have the same problem. My guess is that the subwoofer coil is messed up. You MIGHT have to get it recoiled. But before you do any of that get someone with a sub to play their sub in your car, if it works.... then your sub is messed up, if not.....then your amp is messed up ( trial and error ). Today i noticed my subs rubber surrounding is crooked, that may be the problem for me. Also when I press down on the sub it makes a sticking sound, like something came loose. So once i get everything opened and out ill let you all know the solution. Good Luck!

Try resetting the bios. There should be a hole on the underside of the laptop with letters reading "RESET" in white text.

Stick a toothpick in there and hold it for a few seconds and then try booting up again

Thats because the primavera program that you are using is a old version or it is a educational version. Update it to P-3.1 and then give it a try again.

First thing is to use an ohmmeter to check the voice coil of the speaker to make sure it is not blown open. After that it is into the shop for amplifier repair.

Hi! I have a Behringer B1800d PRO active subwoofer which is acting up. At first it just stopped putting out any sound at all except for a “click” or a “pop” every 5 sec. interval or so. But lately it...

The issue is the power supply inside. There are most likely bad capacitors inside. You can tell in SOME instances by looking at them. They look like miniature can. If they are bulging on the tops or sides or they are leaking a brown substance out of the bottom, they have failed. Please note that they can also fail and show no signs of failure. For those cases you need to get a meter to test them. They are not cheap meters. If you cannot solder or perform other electronic repair procedures, it would be better to send it out for repairs.

Behringer b212 active speaker no sound except weird high pitch feed back and power light won't go on.

i would check the power supply and the power amp! There must be a short in there.Honestly,it needs a well complete check by a pro! Thank's! Serge Lavallee!

Evrything hookup there is no sound iget a good signal in the back of the sub so whats the problem

try connecting a speaker to the sub output terminals at low volume and see if it has loaded output, if it works , your subwoofers voice coil is open/blown

No sound on behringer b1800d subwoofer

HI.. Does it power up ?? If you put signal into it.. do you see the signal LED flicker ? the LIMIT led ?? Need more info.

Behringer EUROLIVE B1800D PRO Active 18" Sub The power comes on Limit LED flashes then shuts down over and over

I had same issues with mine. Check T1, T4 T11 and T7 on Crossover/amp pcb pcb part number is P0981 It is blue in color. These are the output Mosfets. If they short the protection circuit causes unit to cycle into protection over and over. ALSO if they are shorted I would suggest replacing the Gater drive IC IC3 for T1 and T4 IC 11 for T7 and T11 as this is the main IC that drives these MOSFTETS . Here are the part numbers T1, T4, T11 and T7 are type IRFB4227. The IC in mine was type IRS20955 ( Note: this is no longer made by IRC as they had issues with them shutting down and not working correctly, the replacement is IRS20977) good luck.

Basslink has no output, but Power LED and Servo LED always on.


One or more of the DC to DC outputs might be bad. Check the
/- 54v on the main PCB and the /-15v on the switching controller PCB.
Losing one side of the 15v will cause the limit comparator to rail and force the servo protection, even with no input signal.

How to send at same time main mix and alt 3-4 outputs signals

The subwoofer MAY only have a single channel. If so, you would just use either 3 or 4 to the subwoofer.

Normally you would just tap off the main mix. The only reason I can see for using the alts is to have seperate sliders for level control.
