I need to reduce the red level on my screen whilst my PC is connected. Ive tried every standard picture tweak on the main menu but no luck. Does anyone know the system to access the Viera Service Menu. Ive read on American and Australian sites you can change these using the bass and treble settings on the sound menu? Anyone tried this? Im working away at the mo so cant get to my screen... http://www.keohi.com/keohihdtv/brandspecific/panasonic/panasonic_plasma_servicemenu.html http://www.dtvforum.info/index.php?showtopic=12032 http://www.guidetohometheater.com/directviewandptvtelevisions/1104panasonic/index3.html Anyone dare to try?
