Replacement IC... in need

[luvonmik]

Hi...

I am new here and would like to ask some help from you guys. I am currently fixing a DVD player that is not functioning properly. The audio output has a problem maybe because of overvoltage in the input power supply.

Anyone here knows the replacement part for the following ICs: K34063, 3544 & CS4340-KS

What make is the DVD player?.

Toshiba ones have a huge problem with sound faults, caused by faulty capcitors in the PSU. You actually replace two and remove and discard a third - there's a technical bulletin about it.
