[Andrew] sent us this great breakdown of an LCD monitor repair. After his wife’s monitor developed an issue with rippling in the picture, he was forced to decide between trashing it, or taking care of it. He made a decision for the latter, possibly to his wife’s disappointment. The rippling image could easily be attributed to a failed filter in the power supply. knowing that capacitors are a prime suspect in these cases, he tore in, trying to find failures. He found that there were, in fact, 2 bad capacitors on the back light circuit. After replacing them with newer, higher quality ones, the monitor was as good as new.
