I plugged a 120V system into a 220 V supply.

The system comes on, the AM/FM radio works. The 5 CD changer works fine, that is, changing and reading the disks.

The problem is that there is no sound or video from the DVD any more. I changed the IC, RSN311W64B-P but still no sound.

Do I need to change the DV B/E module PCB (Part # REP3380F)?

These machines are solely dependant on 2 main IC's. The power module IC501, and IC502 the power reg. If the voltages aren't correct from the o/p's of these, then you might experience some functionality, but w/o all voltages being normal or missing altogether, you will get error codes for day's.

you blowed up something in the sound line.
if you have no experience let somebody else to fix it.
