I have had my set for 3 years and the aspect control has worked fine in "Auto" mode up until last week, it is now in Just mode all the time and the Auto is not detecting widescreen mode picture. I have a Panny VCR connected via scart and a skybox connected via scart also. The onscreen information shows Panasonic Auto mode and 4:3 and Just only,it would appear that the Just mode is not expanding picture. I hope the above makes sense. Any advice/help would be greatly appreciated in order that i may view in widescreen mode. It would appear that this is linked somehow with premature tube failure...can anyone post "tube failure" sypmtoms please????
