RCA D52W20 Having lots of trouble with a red screen. The screen has a strong red tint all over it with red lines that criss cross horizontally. This started when digital video was installed through the phone company. The first time they turned on the TV after hooking everything up, the TV turned red. They turned it off and it returned to normal. Within a week it started doing it all the time. Now 4 weeks later I have a permanent red screen. I have tried disconnecting everything from the TV. Then I have a red snowy picture. Are there any suggestions? Maybe they set up something wrong on my TV
