I posted this in another thread, but I'm reposting it here to see if anybody has any ideas.
We have a 60" Sony RP-LCD in our house that's connected to our DVR box. The DVR box kept shutting down on its own, going into a protect mode. We are using U-Verse by the way, and have one CRT TV, two LCDs, and a DLP, the DLP is the only one causing problems.
The cable guy tried changing HDMI cables, didn't work, and tried using component video, didn't work. He ran some tests on his little device and apparently the TV is putting out voltage that's causing the cable box to shut down. Unfortunately, I wasn't home when he was here, only my mom was, so I don't know exactly what all he said, but my mom says it was something about 50V+ when it should be 25V or less. He said that the red is the worst offender, and showed us the readings on the little device he plugs into component out, and it indeed did show a reading that was much farther out of balance than the other two.
Does anybody have any ideas on how to eliminate the voltage feedback? The cable guy didn't know what to do aside from "Buy a new TV", which is a lame way to solve a problem. We'd rather not have to go buy a new TV, our DLP is working fine and does us well, so unless we have to replace it, we won't.
