Hi, I have a 1080i HD Ready Hihachi TV.

When I play on my PS3, any game, PS2 or PS3, the screen will go black withing about 20 mins of playing and every couple of seconds it goes black for a second or 2, sometimes the image will come back and carry on flashing. If it stays off it goes to a blue screen and says "HDMI Not Available" or "Out Of Range"...

However if I change the resolution from 1080i to 720p or lower it works fine... When I first had the TV it worked fine on any resolution. I just think the TV doesnt like being on its full capability, although some days it works beautifully...

Can anyone suggest anything... Its still under warranty so I will probably change it if no one knows a solution....

Thanks ever so much
