TV Shananigans


I’ve had this Mitsubishi WD-65735 65-Inch 1080p DLP HDTV for several years (six? I think six, yes) and it’s always been a little janky, with some overscan issues and taking several seconds to change from input to input or channel to channel. It’s always been just good enough to not replace, always been a great TV, so the minor issues that it’s had haven’t really weighted on me. That being said, it was time to replace my $75 wal-mart sorta surround sound system with something that was actually dolby certified and could handle all the latest gizmos and formats that are floating around my living room (usb music, banana connectors, HMDI 4k, 3d, etc etc) I eventually settled on a Sony STR-DH740 7.2 Channel 4K AV Receiver:


This is a very very good receiver. It pushes the speakers I had previously with gusto and the hook up was as simple as plugging in the newly installed banana clip speaker wires and powering it all up. Excellent purchase and I was very happy with the results. For a while. I had it set up for about a week, and started to notice that after it was turned off it would make random clicking noises, the same exact type of noise it makes when it turns on or off, nothing too loud or exciting, but enough to wake you up if you’re trying to nap off a hangover on the couch. Around this time though, the wife and I started painting the living room from a nasty renters beige to a nice home-owners green, so it was moved to the middle of the room and leave it unplugged for a while. After we moved everything back to where it was going to live and we were sitting around the clicking was getting on my nerves, so I figured I’d go all out and try to figure out what the issues was.

A brief amount of google-fu led me no where, other than people talking about blown capacitors or fuses, and I was pretty sure that there wasn’t anything actually broken on it as it was performing very well. Remember I mentioned that my TV had some issues? Apparently it has something known as “HDMI CEC“, which allows the TV to control HDMI devices and HDMI devices to control the TV. Apparently some manufacturers didn’t use the industry spec though and the interaction between my Mitsubishi TV and my Sony Receiver was causing the receiver to turn on, then immediately turn back off every 30-90 seconds. The kicker was that turning this off on just the TV wasn’t enough, I had to turn it off on the receiver as well, and now my living room is click free.
