LG PA 02-07-08 Model VX4500 PPA #54 the speaker stop working.

You should search ebay.

it is possible that the PA speaker output is intended for a normal (unpowered, unamplified) speaker. Perhaps in your case the audio you hear from the PA speaker is only signal leakage from the PA Speaker connection.
To know.. connect a regular speaker to the PA speaker connector (any speaker, home audio, old car 6x9....). If the PA works and drives the temporary speaker OK, and you hear no CB receive, then the PA output is for a normal speaker, with leakage of CB audio.
It is just a guess, but easy to try.

I have a LG VX4500 CDMA Mobile Phone. I need service code to use this phone. I cannot pass the service code. Is there any method to rest the service code?

Have you tried plugging in an earphone in the earphone jack? If you get sound from that, it may be that your jack has an internal fault. This is a common problem. Sometimes just blowing out the jack with compressed air does the trick too.
