Speakers sound as though they are blown but when I removed them from the chasis they look ok with no tears or cracks. What else would cause them to sound like they are blown?
What happens when you gently press on the cone about the centre where the voice coil connects. If the speaker is scratchy going in and out, it will sound like **** also. This is caused by the voice coil becoming misaligned with the magnet center piece in side the speaker. There is no cure for a fault like this on that type of speaker. Replacement required unfortunately.
Seeing as you have it out of the TV, I would as a confirmation that they are stuffed, hook it up temporarily to another audio source, say a HiFi system or portable stereo, just to check them. don't use too much level as TV's only put out a couple of watts, and some HiFi's.... a couple of hundred :) if it still sounds bad (it wont sound great either whilst sitting in free air outside of its mountings), then it is faulty. The audio output stage of the Tv will have a faulty output chip, or perhaps dry solder joints about the output stages. Something that can be fixed if you are experienced with soldering circuit boards. Hope this helps you to sort it out. Ask me questions if you want, I am happy to talk further to you about the issue. Cheers
