Question about Audio Players & Recorders
I have a klipsch subwoofer sub10.
In the user manual it is clearly written that the
subwoofer should be supplied with the exact power
supply specified in the back side of the unit. It is
specified as 230V 50Hz, 1.0 A.
How can I get a proper power supply mentioned in
The subwoofer is down. No response. No LED. But electric shocks observed on the screws in the backside of the speaker when I touched them.
I trying to figure out the reason. This is serious becos it is the second time. First time happed just 10 days from the date of purchase. I got a replacement. This secod one worked well for 4 months and facing the same problem again. I doubt it is becos of the improper power supply against the spec. Please help me in this problem.
As we know in India power goes on and out all day. so avoid using any extensions

No sound problem is power amplifier trouble maybe the IC there is
defected or cold solder of joint of the parts.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
or loose. It is possible that the cold solder is still minimally
(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
provides electrical contact. Jarring the unit creates movement inside
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....
Don't forget to rate;

Sounds like your speakers had too many watts sucking from an amp that couldn't produce the power to feed them.
What is the max watt power output rating for your amp?
Compare the amperage of all the speakers combined and make sure they are 15% lower that the rating on your amp. Be sure to include the sub in your totals.
Chances are you've blown the power supply on your amp.
Have you tried any of these checks yet?

It sounds like I'm in the same boat as you guys. I just wonder if I can do this repair by myself. I have limited electronic experience. If it is just a matter of pulling out "x" and replacing with a new "x", I can handle that... but will I need to solder?
