I recently had my tv repaired for diode problem,it is a samsung LNT4066FX/XAA flat screen.Now instead of clicking sound and not turning on the power bar at bottom stays blue and the picture has color...


Well the capacitor problem usually causes power up problems. If your tv comes on now it sounds like you dont have the same problem.Vertical lines are usually caused by bad flat panel or dirty ribbon cable contacts on flat panel connections.

Colored vertical lines with sound no picture


im afraid to say that your display has gone the best thing you can do is call the supplyer of the tv if its under warranty or call samsung. the cost of a new display will be 400 - 500 pounds so you may have to buy a new set.
