How can I fix my Panasonic Viera TX-L37 U3B?
For the last 3 days I have had a delay of at least 30 seconds between pressing the GUIDE button on the remote and the guide actually appearing. 30 seconds doesn't seem long but it is when watching a silent black screen. Normally it would show the guide immediately. I've put new batteries in the remote and turned the tv off completely overnight to no avail.
Can anyone help me (and my very impatient husband!!)?
