CYaBro: Check the HDMI cable.+1
It could be the TV is losing sync with the PS3 (HDCP issue perhaps)
tornado: Hi i just bought a sony kdl32ex400 i have a ps3 connected via hdmi at a random time the tv will go blank for a few seconds then turn back on any ideas why thanks
Hey, strange coincidence... The 32ex400 display model at my work has been doing very similar things for a while now.
We have it hooked up to a phillips bluray player via HDMI and a few splitters and every so often it will go blank for a few seconds.
I'll be working on saturday and I'm going to have a good look over the setup and swap cables and sources a bit and see if I can find out whats going on.
