Question about Sony KDL40EX400 40 in. HD-Ready TV
Are you connected to a surround sound system?? Which one? I have had the same problem with 2 different KDL40-EX 400's. I experienced picture freezes and non-response to the remote. The unit would not turn off with the remote or the onboard power switch, had to also be unplugged. Removing the HBD-E570 solved the probelm. TV works fine with only the onboard speakers (but sounds like ****)
I think there is a compatability problem between the TV and the surround sound system. (Theory) Could also be a bad HDMI cable (have not yet tested this) or a defective surround sound unit. Anyone hear of an incompatability issue with these units???

This is a power supply problem, meaning either the power board has a fault or is detecting a fault from another circuit and shutting down. It shuts its self down to prevent further damage too the TV and prevent an electrical fire hazard. I know its probably something you don't want to know.....LOL but have a professional technician service the TV or take it back if its still under warranty.
