Many thanks to plazman30 and everyone else who contributed to this thread. I have a Kenwood VR-507 and I use a Harmony 659 remote. I started getting intermittent problems with volume control and then eventually total failure. I blamed the Harmony at first but after trying the original remote I realized that the receiver was the problem. Figuring it would not be worth trying to fix the receiver I was about to start looking for a replacement when I found this forum. I found I had the problem with the solder joints, just as described. It only took about 15 minutes to do the fix. I had to add a little solder on two of the joints. Receiver now works great. Again, many thanks for the great advice including the photos and instructions.
I have had my VR-309 for six or seven years now. To be honest, I can't remember the last time the remote worked properly because it has been years. This past Christmas I replaced this unit with a Samsung.
Not being ready to discard the 309, I moved it to another room in my home. I was thinking that I could continue to deal with the problem on a TV that I watch less.
Last night I googled my way to this site and found this fix. Clearly this thread has been here for quite some time now, but I have only now decided to look for a solution.
Upon first inspection the three solder jonts looked fine. Under magification I could see that one of the three was weak so I resoldered that connection and now it's working like new again.
Many many thanks to everyone else who contributed to this thread.
I can't believe I found this very useful thread! My VR-509 had the same problem for the last 2 years. I was a wits end ready to trash the receiver and get another brand. Thanks to the helpful advice from plazman30 and others here I resolved the problem in a matter of a half hour. I soldered the connections with the board in place.
I should have done a search earlier on, I guess I assumed my receiver was the only one with this problem. Next time I'll be quicker to search for a problem/solution.
Thanks to Plazman30 (Andy) and cntrlwiz (Dave) for posting the pictures and the Awesome fix for the VR507. Being able to solder myself, the entire repair took about 20 minutes. The pictures really helped out.
I bought this Kenwood VR507 with a home theater system. I have only had this problem in the past 8 months... (the unit was in storage for over a year prior to that). After trying new batteries, I found out that the remote control operated every other device except the receiver... I determined that the problem was with the receiver, but did not know what the problem would be. (note the VR507 does not have RF, only IR) Like everyone else on this thread...It worked intermittently, and the odd banging on the unit would get it to work for a short time. I was ready to go out and purchase a new unit and scrap this one. Thanks to the fix I don't have to get up from my comfortable couch to turn the knob up at quiet parts and do the same again when the sound becomes deafeningly loud during the crash scenes. You have saved me (and many others) tons of money and time. Take a bow and accept a wave of gratitude!!
Glad this thread is still active, I have a vr-209 and just tried the soldering fix tho I didnt see any lose connections, The remote is working now but not sure if I actually fixed anything since it was an intermittent problem to begin with, If it is fixed I will know in a few days and update. Thanks to everyone that posted on this topic.
I have a vr-3080 I have the same problem but when I took the thing apart it doesnt look the same? Has anyone worked on one of these? Please help I was about to trash this thing! I might still its pissing me off! Good job to all you guys that have saved all these people thousands!
Wow. It's really hard to believe that these problems have continued for at least 4 years of production runs on these varied Kenwood receivers, and they've done nothing to try to fix it.
I could see if one particular model number had issues, or a number of products that shared the same PCB design or date of manufacture... but this affects a wide range of models, with different circuit board layouts, manufactured in different years, and the problem appears to still be occurring.
Kind of speaks volumes about Kenwood's commitment (or lack thereof) to making quality products.
I still haven't replaced my old RC-R0913 remote. Since, if I want RF, I'd have to buy another Kenwood OEM remote... and I just dont trust them enough to plunk down another $130.
i too have a kenwood vr-3080 functioned well for years all of a sudden remotes (universal, kenwood & kenwood kicker) all stopped working could this be the solder cracking phenomenon?? I can't find the oringinal threads from plazman30 Can anybody help??
This thread has helped me immensely! I bought my wife a new Logitech remote then discovered that I couldn't get the IR to work on my Kenwood VR-509 receiver. It turned out to be the cold solder joint problem described on this thread. I created a web page showing some pictures of the repair. I also took a couple of macro shots of the solder joints.
Here's a link to my web page with the additional photos: [Link: home.comcast.net]
I have had a Kenwood VR-509 receiver for 7 years. The remote stopped working after 1 year. I just found this forum, and after reading all of the posts and people's links (specifically Dave Ditton's how-to @ [Link: buscoblog.com]) I fixed the problem in 30 minutes.
I've never even used a soldering iron before, but I picked one up at Home Depot(a Weller 40 Watt) and then searched for some instructions on NR=1). Shortly therafter, I had the receiver and remote fully functional again. Thanks a lot!
