My Acer 193W display in appear suddenly snow stripes, after careful examination found only in shallow background, like reading the text there, there are some desktop menu, but the dark is no, still can play CS, get a long time did not make clear what is going on. When I was ready to give up to live apart and after the inspection, the monitor upside down in the past in incredibly good, please understand the people look upIt took me an hour to have the snow again, but I got up in the morning and switched on, and I noticed that the snow was only visible under the white background. The other colors were OK, and the film was clear
There are 3 possible areas to judge:1. video card problem(re insert, clean the gold fingers, the fan is normalUpdate driver, you can download the driver wizardIf it doesn't work, you'll have to change it free during the warranty period2. connection problem (re insert, check VGA or DVI interface)3., monitor problems (check the electrical socket is energized. If convenient, then connect to other computers to see whether it is normal)Not yet, a key restore. If you do not prepare the system disk, CD-ROM can be used. Start the computer, press the Del button, set up in BIOS disk start, insert the system disk, and then restart, basically completed automatically according to the stepsNo, no virus inspection system. Only is the heat problem. For a long time, can open the case carefully cleaning the dust, to the fan with a little higher oil. The focus is to reduce the temperature inside the chassis.
To fix the monitor, brush MCU. Or restore the factory settings under the button on the monitor. Maybe it will help you
The clock frequency of the LCD (liquid crystal display) itself is difficult to keep in full sync with the clock frequency of the analog input signal;Especially in the simulation of synchronous signal frequency changing; if the LCD synchronization circuit, transmission line and synchronous signal connections and graphics problems of short circuit, poor contact, and therefore can not maintain the necessary synchronization, there will be "Huaping" abnormal start;General failure point:1 、 interface pin;2, transmission cable;3. Synchronous circuits are generally semi variable resistors that are dirty or of poor quality;After reversing the display, you can temporarily eliminate the fault phenomenon, indicating the existence of poor contact LCD problems, and the above three, the most vulnerable to such failures are first, second, please Louzhu carefully investigated.
