Color not sharp

I just bought a used 53" Samsung on a stand, flat screen and the color is really dull.  I have tried several times to adjust.  The color is just dull.  It only has a red and green tint and the red seems to domintate.  Any help?  Can it be fixed?  Thank you.

This sounds like you have a convergence problem with TV. This is not something you can rectify yourself easily. You need to know the convergence procedure to set it correctly. You need to call a service technician who can complete this procedure for you. He/she can also flash focus for you.

Display Panel faults:
Vertical (source) faults are usually within the actual panel (Lines/Bands down Picture)
Horizontal (gate) faults are unually within the actual panel (Bands/Lines across the screen)

Better take it to a service station to check it.

Bad connections or bad component in video amplifier or on CRT neck board for that color.
