hi guys i just started repairing tv sets.....
in my experience i have this trouble the output from the speaker is not fine, is what you call distortion or noise.
i already repalced the open capacitor but the distortion is still there....
what do you think the possible solution here guys?
can you expalin to me how a filter capacitor do in a audio circuit?
what kind (is it electrolytic, mylar, etc. & when are you going to palce a capacitor in a given circiut?
As in repairing anything, you need to understand how it works first, then try and break it down to isolate where the problem might be. An obvious point to break down an audio fault is at the input to the power amplifier stage - is the sound distorted going in?.
However, a faulty capacitor doesn't sound a very likely reason for distorted sound - based on 34 years repairing TV's!.

It depends entirely where the capacitor is in the circuit, some will be coupling capacitors, some de-coupling capacitors, and some may be used to tailor the frequency response.
You need to post a circuit for specific suggestions!.
As long as the sound is so badly distorted you can hear it on the injector signal, personally I would use an oscilloscope, but a simple amplifier used as a signal tracer would work as well.
the only way an electrolytic can blow is if the voltage applied to it is greater than it can handle. I think that if you connect a bunch of electrolytics in parallel, you get a higher voltage rating.
Oh no you dont!
Think about it, if they are connected in parallel, they will all have the same voltage across them. So the voltage rating of a parallel group will be that of the lowest rated one within the group.
