Kenwood KRF-V7050 remote control problem

Hi all, I have a weird situation on my Kenwood A/V receiver. It seems that when my receiver is turned off for a while, the remote can't operate it (it's in stand-by mode), but if I manually turn on the receiver, then after a while (10-15 min.) the receiver seems to respond to the remote. I've already checked that the remote is outputing infra signal from it's led, and it does. I've even tried a universal remote control with no help. Ideas anyone? I turn on my receiver with my remote (RCR0720) and within a few minutes, my receiver won't respond to my remote when I want to change the volume. Sometimes my receiver will be ok for an hour or 2, but at some point, it won't respond to my remote controller. I have made sure nothing is blocking the air vents of the receiver and I have changed batteries in the reomote; this hasn't changed anything. When I first bought this surround system this was not a problem until after a couple of years. What to do?

Depending on the receiver type, there may be a computer type battery on the circuit board for the receiver's uPC. In some models, they use a gold leaf capacitor that is in the range of about 0.5 Farads or so. This is to store the active memory for the receiver. If the battery or the cap is defective and the temporary memory is lost, then the uPC must re-initialize and
restore the system's temporary memory before it can function again.
If the battery, or the cap (depending on the receiver) is in good condition, then your fault is most likely a component that has become temperature sensitive. After the set has warmed up, the associated function starts to operate again.

    There might also be some bad solder contacts at the IR receiver on the front panel.

HI,

There are two possible reasons.1) It is the senser on the receiver which can be faulty.2)Or the remote circuit is faulty.
If the IR receiver is defective you will have to get it repaired.

Goodluck,

Kenwood krf v5300d


I'd Google "Kenwood KRF V5300D remote control". Surely you will find a replacement available from someone. This worked for me to find one for a LG BluRay player.

I found them in the UK for example, at http://www.findremotes.com/remote-controls-1/kenwood-remote-controls-krfv5300d-1238517.htm

Hay mate i have a kenwood krf-v408od and i dont have the remote. just wondering if i can turn the loudness and dolby digital on without the remote?


http://inform3.kenwoodusa.com/manuals/VR-804.pdf

Loudness: page 19 = Remote only.

The Input Mode key (page 8) selects how input signal are detecetd and handled. DD is NOT something YOU decide on. It is either in the signal or it isn't.

As far as getting the remote goes. It's an RC-R0626. Hit the Search Engines and find one.

Hi, my speakers are starting to sound a bit weird and i think its cause of pplaying around with the equalizers and settings on the Kenwood Amplifier, am just wondering if there is a reset button to restore...


Why guess? Get the manual out and actually look at the settings to see if they're out in space somewhere. If you don't try to understand what went wrong you will repeat it.
