Power light is lit, but there is no sound coming from the speakers , it was working fine and just stopped working ?


Its an PA amplifier and i think this is build with an integrated powerpack IC output stage,
There are different TOA amps but if this model look first the fuses if that are (important)measured defect give a new fuse a try if it blows again there is something wrong in the cables or a speaker conection or filter , ut if the fuses are good there could be an single great brown or black colored IC with STK (....)A or B or something similar is to read on it on the great heatsink inside the amplifier that could be having 15 or more legs must be replaced , BUT also some capacitors thats belong to the output stage because every defect is having a cause.
It think this amplifier IC should similar be looking like this

If you are willing to take a chance...and you have some technical skills you may be able to repair it. I was able to replace 2 capacitors on my power board for under $5. I had no picture, no sound. Not saying that is what is your problem. Search the internet for your model number and no picture. I see several youtubes on yours as well.

Change main fuse but still not working right


First of all, nothing wrong with the fuse. A fuse is nothing but a short piece of wire with a resistance value. If the unit turns on, fuse is fine. The fact that the headphones you plugged in are working tells you that the music is finding it's way up to that point. You must realize that the speakers themselves have additional circuitry that the headphones don't use. If you could obtain a diagram for the circuitry you might find that a capacitor or a diode or a transistor got "zapped" when the high voltage was applied.
If you have this diagram and you don't know what component is defective, can you post that diagram and I would be glad to help!

Hello
It seems that the power supply section of your speaker systen has the fault. Check the fuse inside it. If it found blown out, never replace an other fuse in place. Check the power supply circuit board for any short circuited components in it, before replacing an other fuse.

I have no audio device can not turn speakers on


Good day heigei, hi if you turn on the speakers but no ON lights came on, the problem is your Speakers' power supply stage, either a fuse opens (most likely) or something got burnt from the plug to the transformer, then to the rectifier diodes (got shorted then fuse opens) or to the regulator section. check also the power switch for poor contacts, of course you may need to open the speakers, If by any chance you hear something like hum.... check for open signal wire, check the IC amplifier also, a bad IC amplifier produce no sound or produce a loud humming/cracking sound. If you have no idea of what im talking about, have it checked by a technician. thats it.

The green light on the sub doesnt come on anymore and the speakers wont turn on is there anyway to fix this?


Hi,

Yes it can be fixed but is the catch your Technician should see ( check the woofers powersupply ie the Transformer could be burnt if i is burnt no voltage will go to the system and this ,means no green light no speaker sound.
Now if there is voltege going to the circute then a component is burnt could be a an IC or Transister , Diode etc this area should checked .

Good luck

No power in the system


Did you have to replace the fuse? Was it opened? Sometimes there is a THERMOfuse INSIDE the transformer [xfmr].Before it blows because of too much heat ,it may blow the 2a 250v external fuse.You must check the power supply [the circut attached to the fuse] input should be 120 a/c in and around [+] or [-] 12 v thru 15 v DC output. Look for filter capacitors & resistors that look like tiny cement blocks(they are thermo type fuse resistors) BE KILEFULL !!! (CAREFUL) the voltages are low but the current could be high. Could stop your heart!!

Ensure that your sound card setup/diagnostic software can correctly recognise your speakers. You will need to know what sound card is in your PC. Be carefull with PCs that have sound cards built onto the mother board and that also have a seperate sound card. Ensure the sound card you want is the one you have plugged the speakers into and ensure you have disabled the other sound card and its software.

The speakers don't work anymore...


TheLastStraw,

Pardon the pun, but it "sounds" like you need a new sound card. I recommend TigerDirect for quality parts, service, and shipping.

Please let me know if this helps. Good luck!

Rear speaker not working


If you did the 5.1 sound test and the rear speaker works, sometimes you have to see in your software speakers settings,probably you need to change to 5.1 speakers
