Hello,
my original problem on Philips 42PF5320/10 was: black screen with audio.
I've changed Y, Z anc control board on Philips 42PF5320/10.
Screen is now ok but I see a black horizontal line at the center of the screen.
Another problem is: between dark and bright areas of the image I see white flashing dots (noise).
This problem disappear if I switch source (tv decoder) between PAL and NTSC mode (the TV resets the screen mode and image becomes regular, without noises.
If I use DVI input, the image is perfect.
Could you please help me?
