Often it is to do with the kind of sound that is being outputted by the DVD player. If the sound for example is set to produce dolby 5.1 and you don't have a suitable decoder it will be very low. Check the sound settings of both your DVD player and sound system.

I had this MSG 04 problem. Opened the player up. Messed around. Figured out that the 5-disc tray was hanging up a little during the initialization. The issue is that the tray screws into and rotates around a stand-up beam. On the underside of the tray are gear teeth which are spun by a gear on the main unit underneath. The real culprit is the stand-up beam in the very middle. It is too long. The fix is to first try just tightening the middle black screw holding the tray onto the stand-up beam. If this tightens and MSG 04 goes away, you're done. If it does not tighten at all or much at all, then remove the screw (actually a bolt) and using a razor or sharp blade, scrape the top 1/4 millimeter off the stand-up beam. Apply some grease around the beam and on top. Note, you may have to remove the tray to do all this. If so, that is the most tricky part. Carefully lift on the tray on the front side as you rotate it. Try to free a disc circle edge over the top of the front DVD cover and free the tray. To re-set the tray, put it on the stand up beam with the front side of the tray slanted up and slowly rotate while setting it in and down. After re-seating the tray, screw the bolt down but do not tighten all the way. Tighten it enough to allow rotation and enough to rid the msg 04 problem. I shaved my stand-up beam and have never seen a MSG 04 since.

Usually a fuse blowing immediately means there is a short in the amp somewhere.

Hi,
I'm not sure if we have the same problem here but it's worth giving it a shot. I had this problem too and when I opened the unit, a blown fuse welcomed me. Replaced it, it worked fine, until it was blown off again. I don't know if is a common problem or not, but I guess it just can't handle the entire system.
