Question about Philips Magnavox 27MS343S 27" TV

1 Answer

Overscan is off a bit

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: Overscan is off a bit

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.

How do I enter the service menu on an Emerson EWF2004 CRT Television? (Pictures of the OVERSCAN ISSUE will be provided if needed.)

Older sets had vertical and horizontal size controls. If you have the horizontal size control, turning it counterclockwise will reduce the size of the picture horizontally and reduce the overscan.

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.

The Magnavox 27MS343S is a standard analog 27" TV. It is not high definition and therefore cannot generate a posterized or pixelated picture. I will bet you are using a digital cable box or satellite reveiver and the problem is in that box, not the TV. Hook up a regular VCR to the TV, set the TV to channel 3, put in a good pre-recorded tape and hit PLAY. If the tape plays nice and clear on the TV, the problem is in your digital box.
