I'm glad I found this site and post, this fix worked GREAT for me as well! I took it apart, went over the bottom motherboard solder by solder and could plainly see all the broken and cold solder joints, especialy by the edge of the board where all the RCA plugs lead too and the relays (blue boxes on other side of board). I just tapped 'em with my soldering iron but the solder was so thin it went away, so I applied a tiny bit of solder to each joint and put the unit back together. First try I got a loud buzzing sound and "Protect" accross the LCD, I think I bridged something accidently, so I cleaned up my solders and 2nd try worked like a charm and has been working great for a couple of months now!
