I have been unable to control my VR-505 with the remote control for a long time now. Eliminating all obvious possibilities such as batteries, I attempted to program my Universal remote with every Kenwood code possible and can get no response. My next effort was to install an IR receiver kit using IR emitters, connecting block and IR receiver. My first assumption was that the remote was bad, but after installing the IR kit and trying a few buttons, the IR receiver on the kit flashes when using the Kenwood factory remote. That tells me that the remote is flashing Inferred out of it. And I assume that it is just the IR receiver on the VR-505 itself. How would I fix this? My next attempt was going to be to take apart the unit and resolder the connections, but before I went that indepth, I was looking for advice. Thanks in advance.
I have the same problem with my Kenwood VR-309. Thought it was the remote. So I bought an expensive Harmony remote. It is a wonderful remote, but the same problem. However, it is intermittent. Sometimes the receiver responds and sometimes not.
Sounds to me like the issue is the rx in the unit. It can be fixed with very little work if you can locate the part. Let me take a look and see if I can locate the part number for you. Although I have to say that Kenwwod can keep a tight lip on their parts lists.
Once you're done resoldering, put it together, hook it up, grab a beer and the remote and resume proper couch potato stance! 567 views

I just took my VR-309 receiver apart. If you google this problem, this problem exist in Kenwoods galore and the solution is to resolder the contacts on the circuit board. So, I checked the infrared component on the circuit board. I saw very small cracks in the solder. So small in fact, I had to look at it under a magnifying glass. I wasnt entirely sure it was a cold solder joint but I resoldered the component anyway with a solder containing flux. Before I put the receiver back together I tested the unit and it works great now. You have to have a very fine tip soldering iron for this. Be careful.
I have noted a gradual loss of reaction to remote control of my vr-309. I went thru the same troubleshooting routine, and came to the conclusion that the receiver's IR sensor was going bad. I don't have a fine soldering iron handy and am thinking that the unit is at the point of replacement.
I also have a Kenwood VR-309 and the remote has stopped working intermittently for the last three or four years to the point that it only works when I turn on the unit and it is still cold. I will try the soldering technique and see if that helps. is there any place to get a schematic for this unit? In the old days the schematic would be under the lid.http://www.manualsparadise.com/ReWrite-S...">
Remote control will work sometimes will turn on and off , sometimes remote will not even turn on and off receiver . Remote will not work at all somtimes.
