Have a KDL-40V5100 Sony Bravia. Was working fine, but appears to be having difficulties receiving a signal through HDMI. I've tried this with different inputs, different HDMI cables, and different HDMI devices. 1 in 10 times the TV will receive an HDMI signal, but once I change the input again its gone. Help!
Sorry to say but it sounds like your power supply is bad, although it is possible it is some other components in the TV because turning it off allows all diodes etc to power down completely. Unfortunately after a bit it happens again which leads me to believe again power trouble.
