TV Connectivity
The issue of connectivity between the PS3 and the display is very complex and depends on the type of TV (Analog, Digital or HD Ready), the maker of TV (until recently, only Toshiba TVs have component AV connections as standard in Europe, most other Euro TV sets use SCART which can not carry an HD signal) and specification of TV (the very latest HD Ready TV sets have wider connectivity options than earlier HD "capable" TVs from the same manufacturer which may have lacked HDMI), and finally the configuration of the PS3 model purchased.

I had this tv for almost a year, and I experienced this exact same problem about 3 or 4 times. The only thing you can do is turn the tv off and unplug it for a couple minutes. When you plug it back in it will work. This issue along with the intermittent sound issue on HDMI fed sources drove me crazy until I exchanged my tv for a KDL-52EX700. So glad to be done dealing with Sony customer support...because they're TERRIBLE. I had to email a VP at sony to get any results. The picture is beautiful on the V5100 for a lcd, but it's not worth dealing with the other issues...it's a flawed model. Hopefully your tv is still under warranty...you will have to call Sony and tell them your problem. They'll send a tech to come out, and he'll probably change out the motherboard..it won't fix anything. Then they'll probably send a tech out again to do the same thing when you keep calling...eventually they'll offer you an exchange. That's how it went for me...it was a 7 month nightmare.
