Hello! I’ve recently gotten my hands on a Beomaster 1900. Everything is working well - except the volume control. Whenever i try to turn the volume up on the touch panel, it stops at a certain volume.  The light indicator doesn’t proceed to light up and the volume level stops when touch panel is pressed down. Have any one of you had this problem before? If anyone knows how to fix this problem it would be very much appreciated! Thank you in advance. Cheers, Asger
