Just wondering if you guys might be able to help me with an issue happening at my brother's father-in-law's house... There are three Samsung HDTV's in three different rooms. They all have Scientific Atlanta 3250HD cable boxes via Time Warner Cable. He has DVI to HDMI cables on each box going to the TV's. They were all hooked up this way yesterday and the 700-channels (HD channels) are all working fine. However, none of the other analog channels seem to be working. No video at all. The TV's all display - no video source, no source input or something of that nature. I can get the exact model number of the TV's if need be... one of them is a newer model DLP and the other two are newer model LCD's. Any ideas what might be going on? If using component video cables - everything works fine. Now that we're using DVI -> HDMI... he's having issues. Ideas? Suggestions?
