I normally repair LCD monitors which are heading for landfill, and they are turned over to needy/worthy groups (usually replacing olde CRTs). Almost always, repairs are either "recap SMPS" or "replace inverter transistors", and the hardest part is getting the case apart.
Recently one Samsung 943NWX - presented as "dead" - had an odd outcome. Replaced the bulging electros in the PSU and the unit came to life, but with a dominant pink tinge to the entire screen area. Normally I would ascribe this to backlight end-of-life, but three things contradict this diagnosis. Firstly, hitting the menu button with no video drive gives a small display "Test OK" (or similar) text on a background which is white, so backlight colouration is unlikely. Ditto if the menu system is fired up when a video signal is present - pink screen but the menu b/g is pure white. Clearly the VGA input is being incorrectly processed. Finally, the donor has confirmed that it was white before failure.
Has anyone experienced the video processor taking a hit when the SMPS goes west with faulty caps? Clearly the unit doesn't warrant pursuing a video chip replacement, and thereare no signs of distress on the video board.
