Hi, I have just bought Sony D3550 LCD TV(it has same technical specifications as D3500). I tried upscaling dvd film with Pioneer Dv400V-S DVD player by HDMI(Monster Ultra 600 cable) but some problems occured. When I set the HDMI resolution 1080p from DVD player settings thin black lines appears on the bottom of screen and increases and merge, finally becomes black strips. If I set the resolution 720p screen looks good for approximately 1 hour, after then same damn! thin black lines appears again. I have to set the resolution 576p and in this resolution there is no black line. Where is the problem? Another problem is no sound on TV while HDMI upscaling 720p or 1080p.I tried some TV and DVD player HDMI settings but no success
.
Thanks in advance
