A Samsung lcd tv with whited out picture does not necessarily mean the screen is faulty. It is usually down to a component or two which drives the graphics to the screen, of which we now keep in stock as they are common to a lot of Samsung models and can regularly give other strange picture faults such as a solarised or negative picture.

Not an easy repair, but still cheaper than a new tv.
