My IC BT9843 is burnt I need an equivalent to replace it.any help please?

Try searching again using Google, using BT 9843, but when you look down the results ignore the two letters and see if you can find an IC which is the same numbers, even if it has different letters on the front. Those letters could be just the makers letters, with the device made by different makers.

Sub-woofer quit working. Fuse is good and LED lights up but nothing works. Took out the amp and found that a ceramic resistor C61 on the board which seems to be a 5W1K ohm gets extreamly hot and the ICB...

if you can look at the underside of the board with the resistor on it, take a magnifying glass and look around the pins poking through from the components. It may be that the heat as unsoldered a component (be it resistor, capacitor or otherwise). Look for gaps in the solder around each pin, and if there are any holes around the pins, try filling them in with a little solder.

I have a powered sub-woofer and it was plugged into a regular outlet with no surge protection. After just a few weeks of use, the speaker now pops and crackles when I use it. Did a power surge cause this?...

Sound like the speaker is blown, you don't necessarily see the damage as it could be near the coil. of course there are components you can changed out.

Plug the speaker to a known good output from the other components. if it works, then it's your output, if it does the same thing, then it's blown.

Something is shorted on the circuit board, could be anything - switcher power transformer, rectifier diodes (or a bridge), resistors, blown, dried, leaked or shorted electrolytic capacitors in the power supply section, possibly any other shorted components in any other section.

If you're lucky, there will be visible damage to the faulty component, otherwise you will need to measure the components to find a short.

Anyway, it could be something as simple as a shorted diode or resistor in the power supply section, but i can't say anything for sure.

Hope you can get it fixed...

Bose acousticmass 15 sub-woofer making a noise

The sub contains the amp for the other speakers. But it sounds like the amp has a seriously damaged section and will probably have to be serviced by Bose.

Subwoofer not working

if u are a technician then its easy to check, problems are, blown fuse, power amp IC output transistor may be blown, check for burnt componenets. changing and blowing a fuse means ur output IC or transistors are shorted.

No Power - LED not lit.

Open up the back of your gale 3080 and check the 2 fuses situated near the transformer.They look like 2 silver cylindrical shapes.Check that they have not blown if they have the will cost you around £2 to replace.Better than the 50 quid you will pay when you take it to your hi fi dealer to open up the back of it.
