    Vizio LP2626: 2nd Thread

    When I first got this monitor, it had a "color shift" issue where the black areas would suddenly burst into dark blue, and the reds would burst into fucia (pink). I tried to adjust the settings which worked for a while bit eventually the monitor failed completely, and I had to perform the repair of some caps in this thread:

    At first the repair was successful, but after a couple of weeks the color bleeding/blotching is happening again and I wonder if it's a precursor to another permanent failure of the caps I replaced. Two parallel sets of high-voltage caps and I replaced all four of them with higher quality caps, instead of just the single cap that burned.

    WERE those caps higher quality? Are they failing again? I wonder if they were originally installed backwards. Is there a design flaw to the high-voltage circuit or is the problem somewhere else, and if so where?

    Any help appreciated and thanks in advance.

    Backlights are for providing light source, it can be from CCFL, or LED, nothing to do with patch of color on the screen.
