My new 100 Hz Philips TV plays the sound of 'home made' DVDs and VCDs but shows a white screen. I've tried all the obvious picture format variations offered on the TV menu. The discs play OK on my old Panasonic TV. Similar Panasonic DVD players are used in both cases. Commercial DVDs play OK on the Philips.

Can anyone explain please - and if possible suggest a solution?

Thanks

Brian
