Not damp, not what is abnormal, there is a little blurred, eyes look very difficult, but do not know how to adjust the clear, before Baidu seemed to see some people say that computer has focus, master who will not be a problem here. How to tune?? please give me a detailed modulation step point.
Remove the rear lid of the display. On the motherboard, you'll see a high voltage pack (with two fine tweaks, one with accelerated poles, one with brightness, and the other with focused focus).
Open the cabinet cover (most display using buttons instead of screws, such as PHILPS in machine buttons on both sides of the upper part, in case the corresponding hole demolished when the press can open, look carefully under the authority not hard breaking). In the right after the motherboard has a large component, there are two thick lines into the tube and seat tube, this is called a flyback transformer, high voltage. It is often said that. In the bottom of the high pressure package, there are usually two knobs, and some do not remove the shell can be adjusted, the two knobs are accelerated focus potentiometer, remember the initial position, be careful to try to adjust, the range is small, the speed is slow. When the potentiometer is adjusted, the screen is bright and dark, and the focus potentiometer is clear and fuzzy. After the test, adjust the acceleration potentiometer. After the start of high voltage package has Shijiqian volt, the main floor carefully oh!!
Remove the focus adjustment on the high pressure pack on the rear cover circuit board until only clear, with two fine adjustments, and the other is the acceleration pole, that is, the background brightness. Specifically, I forgot about that one, when you tune it down a little bit
