hi there hope you can help. we just bought a sony KDE...37 plasma for 2,500 and are diasppointed with the picture quality. COlour tones are poor, and with skin tones, and around lights instead of it being a smooth colour you get almost rings around them. We have played with the settings, looked at the input (cable) and can't seem to resolve it. Any ideas? Is it a fault with the plasma or is there something that will fix this? Many thanks for any advice !
