I recently bought a Philips 32PW9618 set and wonders about these things... 1. Can anyone confirm how to find out what tube is installed in this set. 2. This modell/set doesn't seem to support autoswitch between 4:3 and 16:9. It doesn't switch when getting a 16:9-signal. (I don't want to use the "Auto"-mode) This is supported on other sets since at least 1999! But NOT on this set?! 3. When connecting the surround-speakers with optional method (cabling instead of wireless), a very annoying sound starts when switching off into standby. 4. How do I reach the service-menu on the 9618?
