Hi, I have the Sony KV-27HS420 Hi-Scan, and it has problems because the picture flickers/rolls a lot in all the inputs except HDMI. I observed that the menu box isn't affected by the flickering. Plus, in the HDMI input, the colors are just shades of green and red, on the other inputs, the colors are ok, and again the colors of the menu are ok on HDMI. Please I need advice on what's going on with the tv. Thanks in advance.
