I appreciate the subject of a green screen is an old one and can be symptomatic of a hdmi handshaking issue. My T2 works fine with my 5 year old Panasonic plasma. I bought an ST60 and got a green screen that wouldn't go. I checked with Humax Support. They say they have a lot of compatability issues with Panasonic and unsuprisingly blame Panasonic. I called Panasonic - they have no idea. I have the correct software. I have tried turning the TV and Humax on in different orders to no avail. I have tried toggling the V format. Nothing. Strangely I tested the T2 with a display model in the shop and it worked. So I took a new one home - green screen. I went back to the shop and tested the T2 on a different model - the higher spec GT60 - green screen. I am keen to buy a new Panasonic plasma as I like the picture and don't want an LED model. Any ideas on how to solve this locked green screen with new Panasonic TV's?
