I have a friend who is in an assisted/skilled nursing facility. They just got Directv installed last week. Typical "hospital' type room with built in desk between the foot of both beds. Feed is single wire out of the wall and split to the two TV's. The issue is one box will work for about twenty minutes then will freeze on any screen not live TV. Live TV continues in PIP. About 5-10 minutes later it tries to reboot sticking on a Searching 771 pink screen. Five -ten more minutes and the box shuts down. The box gets very hot. My first thought is a defective box overheating and trying to reboot/search until thermally shutting down. I've tried every combo of cables, power supplies and sides of the splitter. The problem always follows the box. The D installer is convinced it's a distribution/cabling issue and I'm never there when he is to hear what he suspects the problem actually is. He's already been back three time with no fix. Any suggestions? To top it off both TV's are same brand and all remotes work both TV's.
