Is not gonna be cheap. with material and labor costs being what they are, it is today cheaper to replace the set with a new one and a warranty to boot.

The colours are no longer lining up. On captions you can see the three seperate colours. The auto focus does not fix. How do you enter service mode to adjust grid lines?


U can't do any grid lines adjustments for this problems,the tv problems it is having are known as a convergence pictures problems,it is dead.The tv have any colors lines like R,G,B mis alignments,tv have any colors shadows pictures or have a 3D pictures look alike?Yes,than the tv convergence board it is dead for the tv to causes all of these convergence pictures problems.The tv convergence board must have to be repair like replacing 2 STK convergence ICS and some or all of it resistors too.To fixed the tv convergence board to solved the tv convergence pictures problems.The tvs shops will cost like $300-350 for parts and labors.

Samsung SP47W3HFX tv blue flickering curved line..


If the lines are slightly curved and stationary on about 2/3 of the screen its either the Blue CRT or the Blue CRT drive board which is having the problem.

Convergence problem


Hi there!
You would need the manual to adjust the convergence. First to correct the curving and then to line up the colours. Not too sure wether you need a service remote or the one that came with the set. If no adjustment takes place when you adjust, replace the Convergence Amp IC'S. Good luck,JUS004
