I have a STR-DB930 Reciever from SOny and i had it couple years now and I love it. I have now encountered a problem and I need help. The volume wheel has a red light to show the position or the level of the volume, this lamp has stoped to work. the problem is when i turn on the reciever the lamp works for a second the stops to work. What can I do myself to fix this or must I take it to sany service center that will charge me alot of money? Please need help!
