Cable input I have a problem that appears to be related only to my coaxial cable input. I get static, lines across the screen or a "no signal" error message. This effects both visual/audio. The same problem occurs with my VCR, which also enters the TV via the coaxial cable jack. I've tried bypassing the VCR completely, and changing the cable, but the issue still occurs. It is not the tube itself, as I still have a perfect picture when viewing DVDs via the component video inputs. Also very unique, and perhaps indicative of the cause of the issue, when I use PIP, the issue only occurs with the primary picture. The secondary PIP (picture in picture) is perfect, and the problem does not occur. I do not have other devices, such as play stations, etc. in the house, so that is clearly not the cause of the issue. I suspect that the issue is occuring after the coaxial cable signal enters the TV, since the problem effects the primary picture, but does not effect the secondary PIP. I've been forced to watch TV using the PIP until I can determine what the problem is and what it will take to fix it. The TV is too big and too heavy to take to a repair shop, and wouldn't fit in my vehicle even if I could get it to my driveway. Any suggestions on what may be causing this and whether it is a simple repair?
