TH-42PX60U with XBOX 360 issues

[dreamaz]

Sorry wan't sure to post a new thread on this or just work with the existing thread.

I bought the TH-42PX60U this weekend along with the xbox 360. Set the xbox for HDMI. When i started to play Gears of War, i noticed that everytime there was sound involved (gunfire, sound effects) i woul dget these red horizontal lines across the screen. It would look ok when i was just standing there but when i moved or fired i had them. Also, sound only game out of one of the speakers and a buzzing sound out of the other. So i unplgged the RCA for the buzzing speaker and got sound only out of the one, but still red lines.

Decided to unplug the xbox and put straight into my standard 27" RCA box and works perfectly, no lines, no sound buzzing. Would anyone know what could be causing this?

Thanks for the help
