My 42PWD4 has recently developed a problem to do with receiving signals from its remote control. I have it linked to a TU-PTA300B receiver which also has a remote control. The 42PWD4 has speakers which I use for TV viewing, but otherwise I mute the sound and use some AV kit for watching DVD movies. Here's the problem - the 42PWD4 has stopped responding to all commands from it's own remote control. There are some buttons on the PTA300B remote control which are supposed to control the 42PWD4 (power on/off, input select) but these do not work now. I have a sky remote which was programmed to turn on/off the 42PWD4 control the volume and mute, but the display no longer responds to that too. Now the 42PWD4 responds to the on/off, input select and volume control and mute (and other functions) for the PTA300B. This is really annoying. If I need to go into setup for the 42PWD4 I get the plasma setup screen as well as the PTA300B setup screen (underneath it). When I send a RC command I can see the green light on the 42PWD4 flicker so the infrared receiver is doing something, but just not interpreting the commands meant only for it. I'm fairly sure it's the screen that's at fault as I think it's unlikely to be a problem with three seperate RC's. Any ideas what I can do about this? I contacted Panasonic support who took my number and said they would get a technician to call back. They haven't. I've tried contacting them again but just get a recorded anouncement saying they are busy and the line is disconnected. I'm hoping there might be some tweek or system menu I can get to, to reset things. The 42PWD4 has an RS232c interface and VGA o/p, so I can connect my laptop to it if necessary. Thanks for any thoughts.
