Hello
Distroted sound may due to some fault in the speaker or its ouput stage inside your TV. You jsut open your TV and unsolder the wires from speaker, and solder it to an other speaker and see whether the sound is normal or not. If it is normal, you can make sure that the speaker of your TV has damaged.
Other reason is of some fault in the output section of your TV, which is integrated on its circuit board. You just locate the audio output section on the circuit board. it will be an Ic that drives the speaker. It can be located very easly following the speaker wires. usually it is screwed on to a metal plate, and will have a number printed on it. Sometimes there may be some bad solderings on its leg solderings. You just resolder all the pins of that Ic by applying a little more solder to its points, and see the effect.
If this cannot rectify the problem, just resoder the Ic out from the cirtuit board, and go for a same type and number. Replacing it will solve your problem. Ok

    Hello
    Here there iwill be no problem for the supply rails to the Audio Output Ic. The fault lies related to audio output ic itsef, or speaker, or surrounding electrolytic capacitor. If any direct short is there, the load resistor connected to the main supply to Ic will get open, and supply to Ic itself will get opend, and no soud output will be there. So here it is sure and certain that the above only will perist.

Just contact the authorized service centre for Philips. Other wise you should have keen knowledge in electronics, and should have enough tools to replace the components. It is Philips. Not a Chinese one. Just understand it at least.
What help do you expect? Do you think; you can? no. Never..
Try it.
