My plasma has developed a fault with the component [AV1] video. The picture appears very dim and dull. I have always connected it to my ntsc us xbox through component with no problem at all. But recently the colour has become very dim. This cannot even be corrected with the basic settings the menus allow? All other connectionsAV2, AV3, AV4, DVI, VGA work fine. DVD player or Xbox works fine when connected to different display or via scart etc. Unfortunately, the item is just outside warranty period . Has anyone has a similar problem? Is there anyway of accessing the service menus to recalibrate the component video [AV1] picture settings? Do you think I would need a new terminal board and can I fit this myself?
