    bn41-00944a succesfull component level repair?

    I have a samsung lnt4069fx with gray/white screen issues and slow blinking red light.(see pictures) It has a bn41-00944a frc which apparently goes bad.

    tv red blinks the same way with that board disconnected from the motherboard

    So far Ive tested the 5 pins voltage regulators and they output the correct voltage at 2.5V and 1.8V. I tried reflowing but the heatsink wont let me heat it correctly

    All Im seeing is people replacing the board altogether. Anyone ever fixed one?

    What do you get if you have the ribbon cable between the T-CON and the LCD panel connected one at a time?

      Hi, Did you ever resolved the issue with the white screen? I have same issue as well.
