Not responding to remotes

I've owned an Onkyo DS696 receiver for 5+years. Every once in a while (when it was on for a long time?) the receiver would not respond to the remote. At first it could be "fixed" by a simple power cycle. It got worse over the years, and finally the unit would not respond to the remote at all. After reading a post here that made perfect sense, my husband and I opened the unit up, and (even thought the solder at the IR connection LOOKED fine, we resoldered it. (He knows how to do these things expertly). We screwed the unit back together and VOILA! it works perfectly now. Even if you don't know how to solder, if you brought it to a repair shop and told them exactly what the issue was and how to fix it - you can save your sanity and the unit. The solder joint I'm talking about is directly behind the IR on the front daughter board.
