Samsung Model LN46A530P1F LCD display issue

[tech2014]

I have an LCD tv with a display issue. When the tv is turned on the display is wonky, then after about 20 minutes it is normal picture. Is this a display issue or something else?

Could well be a tab bond issue, plenty written on what you can do to correct it, albeit temporarily.

How difficult of a repair is this and how long does it take?

If its a part that's mounted ON the tab that goes from the glass to the board, then the set is toast.
Those parts on the actual tabs are the driver-chips and are unreplaceable.

Give us a picture of exactly what you mean.
