Hi everyone I've had my home theatre system a few years now. It developed a problem where it would say no disc but if I switched it on and off a few times it would load. It hasn't done it for a while but tonight I went to watch a dvd and it just keeps saying no disc .I've tried about 8 dvds and none will read however it still reads and plays discs with avi files on them. Im not sure if there's a problem with laser or something but I was hoping someone could help. Thanks in advance.
