My Sony KW-34HD1 came with its own DTV receiver which connects to the TV via a Sony proprietary cable. Since I installed a Sony HD100 receiver, I no longer need to use the original receiver and cable. Now, every time I turn on the TV I get a message telling me to "Please check the DTV receiver connection". The message stays on for about 30 seconds and is quite annoying. Sony service has been NO help (other than telling me to try "setup" or "hook up the old receiver" again). Any helpful ideas would be greatly appreciated.
