I have a 2-year old 17" NEC LCD Monitor (LCD1735NXM), which has developed a faint buzzing sound, along with the screen going completely pink intermittently. When I tap on the case, the sound changes slightly, and the screen goes back to normal for a time.
I have an electrical background, but before opening the monitor, I thought of getting some ideas whether this sounds like a bad soldering connection, which may be fixable, or whether this could be the sign of something else, and not worth fixing. Thanks for any feedback / experience someone may have with these monitors. Ken
