Hi,I have an Epson Tw450 that when connected to a Panasonic bluray player looses sync after around 25 minutes,the Epson displays a blue screen and the bluray player says hdmi on its display,then the picture returns. This goes on randomly for up to 10 minutes until it settles down again,it also does this with dvd's. I have tried two hdmi cables one 10 meters and another 5 metres long. The hdmi cables are connected directly to the bluray player and not through an amp. I have used the Epson with both freeview hd and satellite hd receivers with no problems at 1080i using the same hdmi cables. The bluray player works perfectly with a panasonic plasma tv. There is nothing I can find in the epsons menu to alter settings to give a reliable picture. Any help will be greatfully recevied.
