If the fusible resistor is open, yes it could cause this problem. Check for others in the area as well. Is that resistor 3.9 Ohms?
I'm guesing yes. This is likely the current limiting resistor for the IC. There should be another for the other IC as well. Look for pico fuses in that area that may be open.

My samsung rear projection tv has a problem with its convergence ic. i think theres two ics , but how do i tell which ic need replacing??


Always replace both once your going to the trouble each IC is usually less than $30.
This link will help show you what's involved.
convergence output IC problem. convergence board would have to be removed - remove and replace 2 STK IC's and check the surrounding resistors. Shops usually $200-$400 Be sure to vote/rate me if this helped Thanks!
