Hi, I have a Philips 28" (PW6515) which has recently started playing up. The screen is bowed-in at the sides and none of my external channels work, so no video, digital or PS2 (s-video). When it went wrong all my channels were lost, so I'm wondering if maybe the external channels are 'lost' and I maybe I can get them back using the Service Menu?. The Service Menu is a problem as well cos all I get on screen is 'SAM' in the top-right corner but nothing else, what am I meant to do from there?. Any help would be appreciated, thanks. Kev.
