Have this 27" magnavox (27MS343S) which seems to have a problem with the overscan. it looks as if the TV is trying to show a 16:9 picture b/c it cuts off the sides. Unfortunately there's no 'format' setting in the OSD menu to change it to 4:3 or 16:9. I'm told it used to be normal, but at some point it changed to this excessively large picture. how can i adjust the picture size/format? I've tried entering service mode using some of these codes folks have published but this 2003 model TV doesn't seem to accept them. i'm not even sure this is fixable in service mode. Any thoughts?
Does's the set have a repair history? If it was previously serviced , the capacitor which is connected between the emitter and the collector of the horizontal output transistor transistor might have been changed with the wrong value, which would cause and overscan situation.The service menu for this set is even hard for technicians to use. It' my opinion if the service manual will not correct the horizontal width, the wrong capacitor was probably installed. Scrivitron (also these sets are known for the forementioned capacitor to short , flame or open.
