Need some help here. I had my loco train shop send in under warranty my PRR GP-30 to have the sound board changed out and it came back with only the head lights working. No marker lights (front and back), no number board lights (front and back), and reverse lights. The train shop owner indicated that Lionel had informed him that this might happen and I know for sure that the lights worked just fine before I gave it to him to send in. Has anyone had this problem and is there a fix. Grant it, Lionel sent it back with a working sound board but come on, no lights. Please advise,
