Changing components at random is no way to fix anything, you need to fault find.

It would also be helpful if you had your location filled in, and mentioned what model the set was.

Nigel is correct, a model # is basic.

But let me get generic:

Did you put an ohm meter across the speaker?

Subsitute with a known good speaker?

Make sure there isn't a broken piece in the head phones jack?

Look at the audio output ic. Is it cracked?

Lots of simple things to check.
