Electrical Engineering - Samsung TV Convergence problems


Expert: cleggsan - 12/12/2006

Question
Suddenly the screen on my Samsung HCN4226W arched at the top and colors red, blue and green became mashed together. Initially the bottom half of the screen was OK but an hour later it distorted as well. It is like looking through a glass and the figures and letters on the screen are superimposed over each other. Everything has a halo effect.
Later the next day the picture went completely and the video on the TV will not come on. You can hear it attempt to power up and then stop. Will not work in any mode, DVD, VHS, ext... The sound continues to be fine. Any help would be appreciated. I have done some research - should I replace the "convergence amplifier chips and/or the complete Board.

Answer
Yes, I would say it is a failure of the STK ICs in the convergence circuitry.  They must be replaced with a skilled technician who knows how to solder and who can apply the heat grease perfectly.

It will cost $400 plus or minus to have a shop come in and do it.
