I have a HC5 and there’s one issue with my PJ that is quite a problem...
When I turn on the projector everything works fine if no picture source is connected/on. But, if I change the input selection i.e. from HDMI 1 to HDMI 2 (picture source -a laptop- already on) PJ kind of hangs up and does not response to any button, not even those which are in the PJ itself. Picture is displayed, though. Same thing happens when I turn my AV receiver on and PJ is already on (and HDMI 1 where received is connected is already selected in the PJ). I haven’t tried to change the input selection when AV reveicer is already on.
So, I have my laptop connected to PJ's HDMI 2 connection directly. If I turn the PJ on first and laptop second PJ hangs up the same way (HDMI 2 already selected in PJ) and also if the laptop is already on and I turn on the PJ. To get rid of this I need to unplug the HDMI cable and the put it back (maybe turning off and on the picture source would end in the same result). After a while PJ's both lights (Status and Power) are blinking and, of course, that kind of situation is not mentioned in the users manual. After a while only status light blinks and power light is on. I can’t figure out status light’s actual color when it blinks… PJ is on the shelf quite high, light looks red when watched above, orange then watched from side and there’s also some green in it when watched from the back :/
I can start the PJ again but it ends to the same situation (buttons don't work). But if I unplug the power chord and plug it in and start the PJ again it works just fine (laptop is on all the time).
Only once I’ve managed to use the PJ without this issue: I first turned on my AV reveicer, then BR-player (connected to reveicer) and then PJ which had HDMI 1 already selected (receiver connected to it).
I will test what will happen with s-video cable, I’d suppose that this problem has something to do with the HDMI “handshaking”. I tried HDMI 1.3 and 1.4 cable between laptop and PJ but no change so I don’t think this could be caused by a HDMI cable alone. Have any of you ever heard or had of this kind of problem? It’s hard to believe that the problem is in the PJ itself since it works normally after unplugging. If it was broken I think this "hangup" would happen every time when using it, even after unplugging the power chord.
Without movies... there's no life...
