I'm not familiar with your exact product, but Parts Express sells all sorts of replacement in-speaker amplifiers. I've replaced several powered subwoofer amplifiers with their products, and the customers usually report-back that it sounds better than when new. You might want to check them out, and see if they have one that will fit.

How do I fix portable speaker will not power up


You will have to try to find the damaged component(s), which means disassembling the speaker. Once you find what parts need to be replaced, you can order them from an electronics supplier such as Digi Key or Mouser. Replace the components and continue from there, as additional troubleshooting may be required.

How To Bi-Amp And Bi-Wire Speakers!


What is the difference between bi-wiring and bi-amping?
Bi-wiring is using the same power source (amplifier) but separately connecting that power source to a woofer and a midrange/tweeter on a speaker.

Bi-amping is using two separate power sources (amplifiers) and connecting one amplifier to a woofer and the other amplifier to a midrange/tweeter on a speaker.

How do I bi-wire?
Your speaker must have two separate positive and negative connections (one set for the woofer and one set for the midrange/tweeter). Connect one wire between the positive terminal on the amplifier/receiver the positive terminal on the speaker. Connect the other wire from the negative terminal on the amplifier/receiver to the corresponding negative terminal on the speaker. Remove the jumper straps connecting the two sets of speaker inputs. Repeat this process for the second set of terminals on the speaker, connecting them to the same positive and negative terminals on the receiver/amplifier. Repeat the steps for each speaker you wish to Bi-Wire, connecting them to the appropriate terminals on your receiver/amplifier.

How do I bi-amp?
Bi-amping is similar to bi-wiring, but involves separate amplifiers: one for the woofer and one for the midrange/tweeter. Passive bi-amping involves a direct hookup between each amplifier and the speaker terminals. True bi-amping involves hooking the preamp to an electronic crossover that replaces the passive crossover network in the speaker. The active crossover then connects to multiple power amplifiers.

I have a samsung ht-h7750wm and can't get the centre speaker working can you help


Check the speaker first. If found OK, the internal amplifier stage circuit to the set is faulty. If the speaker is found damaged, here too the internal amplifier circuit fault; a direct short circuit. If so, without rectifying that fault; never connect a speaker in place, as there is chance to the speaker that you connect too will get burned.
It will be best to contact any service technician in this case; I suggest.
If you wish to get some details; check the site linked here. Pull up older posts. Surf the site with patience. http://electronicshelponline.blogspot.com/

Hi there was a pop and burning smell from the box. I guess its bust but hope it can be repaired as I cant find a replacement anywhere.


Unfortunately it does sounds like there has been a system overload. Your speaker is an active system meaning it has its own power unit inside. Somewhere in the internal amplifier there has been a circuit burned. I have copied the link to the contact page for the stereo repair search website. If you will do a search for your state information, this site will locate a repair service near you.

Adding remote control activated ''mute'' to TV headphone jack


Generally when the head phone jack is inserted the speakers will get disconnected automatically.

If you are going to use external amplifier you can try the AV sockets. Opening the TV you may require the special screw drivers some times.

Noise on speaker directly connected to samsung PSX2P2SBX


On the sound pcb attached to main pcb in the seperate box are two 1uf, 50 volt surface mounted elec caps. These go leaky, and sometimes take the chip with them. You will need the right gear to do this job. £12 .00 for parts including chip.

Convert passive speaker to active


You don't say anything about your passive speaker, only thing that I understand you have a Yamaha AX-396 witch have an Power output of 60 watts per channel into 8 ohms (stereo)! That means working great with your passive speaker!!!

Buzzing in speakers on Carlsbro Marlin 8400 Power Amp


Hi,

If your volume is down and there's a hum, then it could be that your capacitors in the power supply are blown. Also there could be a problem with the bridge rectifier, possible that there's 1 or more diode's defect. Any technician can reapir that.

Hope it helps,
Gerard
