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?

Re:
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.

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.
do you mean the top of the picture is cutt off? if so then go into tv menu and set screen size to 16:9 not auto. if that doesnt work then try settings on ps3 hopefully that works
There are vertical and horizontal adjustment in the tv, however it requires removing the rear cover.
If you are unsure of the adjustments rather let a qualified tech service the tv for you.
It will accept a 1920x1080i input from a high def source , but running a PC at 1920x1080i/p will cause the problems you describe, depending on what the PC is sending to the TV, because PC signals are not the same as high def.
Your PC should be set to a resolution as near to 1366x768 as possible. My PC allows 1280x768 and 1360x768. Try one of these for best results.
There are no settings on the TV to solve this problem.
Switch to that input, and run the Auto Convergence for that input (Setup menu on the TV, Convergence). Convergence settings save for that particular input.
significant vertical overscan. It is such that it's impossible to read crawls and such at the bottom of the screen.
I think this problem is a tv problem.
it is due to vertical section.
please change electrolytic capacitor in vertical output section. it will be ok.
it is common problem can be fixed at home & very simple.
