    Sharp LC32SH20U & AS15-F

    I came across an lc32sh20u that power up and than display a fainted white picture. I check the T-CON board and it have the AS15-F gamma chip.

    I replace the AS15-F gamma IC chip, now the picture is normal but now anything display on the LCD screen slowly fade away and it back to no picture. It doesn't matter what is on the screen, if it the main menu or the input menu they both fade away.

    If I input a signal to the HDMI same thing happen, picture fade away. I do have sound. So I'm wondering, if the T-CON board is bad or the LCD screen.
Working...
