2. If it is a host failure, if there is no signal display output on the host, see if the running sound in the host is normal, if there is an abnormal BIOS alarm sound, refer to the relevant instructions of the BIOS type to discharge the problem; If there is nothing abnormal and it is powered on normally, it is recommended to turn off the host, unplug the power cord, clear the static electricity on the body (simply touch the water pipe), reseat the board and interface, and clean up the dust, it is best to discharge the BIOS, reinstall it, and find out the symptoms!
Third, the display does not display (there is no display at all, and there is no square display with the words please check the signal input), the main problem is generally that the high-voltage bar is damaged, at this time the power indicator of the display is still on, but it is not displayed, and there can be a faint image display on the monitor with a flashlight, and the high-voltage bar is replaced; If the indicator light is not on, it is generally because the power strip is broken, and replace the power strip.
Fourth, if there are stripes or other abnormal colors displayed, check the driver board, replace the screen cable, if there are bright spots or dark spots, irregular dark blocks, etc., generally the LCD board is broken!
The above belongs to personal hard typing, not copied online, please respect the results of personal labor! Don't ask for points, but ask for help!
