Page 1 of Kenwood KRF V7030D Remote control problem (problem in receiver, not sender)

Hi,

The problem I have is that the remote only works after the receiver has been on for half an hour or so. Before I go hunting for dry joints and dodgy plug connections, does anyone know if this is a common problem with this model, and maybe whether there`s a capicitor that needs to be replaced?

Many Thanks,

Jim.
