I just wanted to say thank you as I read one of your posts about Pioneer six disc changers that won't play. You mentioned the laser lenses often fall out. Well mine must have popped out in shipping, as soon as I removed the top, out jumped a laser lens that had come loose. Glued it back in with gorilla glue and now the player works great. Its a PD-M400 and quite minty, I'm now thrilled that its working again.
