Facing TV Problems? Ask a TV Technician.
Hi and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, is the TV directly connected to an antenna? ...or is there a DTA converter or cable box? ...or even a satellite receiver? Or an external source such as a DVD player perhaps?
Still, 'PICTURE' menu settings are generally dependent on the user preference and the light condition where the TV is located. Please click HERE.
Alternatively, if a particular primary color is too strong, OFF or MISSING (green. blue and/or red), then it would be an internal hardware issue. If so, are you then considering a DIY (do-it-yourself) repair approach? If yes, do you have access to and familiar with a multi-meter and even a soldering iron?
