Hello, I have 8 superfine pitch SONY tube 16x9 TV's but this is the first one I am having a issue with. The HD signals to the set, both ATSC over-the-air and HDMI BLU-RAY signals jump and hop randomly for the first 15 minutes of the sets warm-up and then the image becomes solid. Not issues with color or sharpness. The weird thing is that the SD signals (both in the tuner and composite inputs) are solid ALL the time, even during first power-on. Any help would be great! Links, Tech info, Service Mode tips, or parts advice or e-mail links to TECH GURUS would be awesome as I love these old sets and hate to see this one die!!! Thank you, Uvaldi.
