Hi, this is my first post and I'm a complete newb when it comes to MD. The problem I had with the MD MZ-707 Type R only happened a few days ago. When I put a disc in the track can be played and such, but theres no sound coming out! Everything shows up on the display menu but even when the volume has turned to maximum, theres no sound coming out from the unit! I'm pretty sure my warranty has expired by now since I did not buy extended ones but if someone could post a solution that could save me money from sending it to a repairman, then please help! Thanks
