Question about Televison & Video
The picture looks to green like the blue is missing ,I do work with small tvs wath I need to do to fix it.
Hi and welcome to FixYa,
Just like in small TVs except multiply it by 3. There would be a squarish PCB at the rear of the CRTs/tubes containing the color drive. Often problems are cold solder issues and/or loose connection. Worst case scenario is a defective blue tube.
I would suggest the best/initial course of action is to get hold of a service manual or at least a schematic diagram with voltage readings and follow checklist/diagnostic procedure.
Good luck and kthank you for using FixYa.

You did not say what type of TV you have. A flat screen plasma, LCD or a CRT (older picture tube type)? The fact that you can get a black and white picture just about rules out a problem with the plasma, LCD or picture tube display. The fact that a color picture is only displayed in shades of blue and green points to a lack of red. This can be as simple as adjusting the tint, or can be caused by a defective red video stage, usually the output stage, or a dead color oscillator. In the latter two cases it is a circuit problem and would require repairs. Service on TV sets as you may know is no longer inexpensive. Find the tint adjustment first, the kids may have gotten it way off. Put the bar in the middle, or if you have a reset option which returns all picture settings to the levels set at the factory try that.
