hyundai monitor problem
Hai friend
Its the problem of the LCD driver section, which is not driving pixels on that area. If you are sound in electronics, you may try to open the pannel and try to find any sort of loose contacts, dry solers on the connectors and the Driver PCB, fungus formation or a torn ribbon cable connecting the LCD to the driver.Frankly speaking if it was my own monitor i would have given it a last try. But after that if nothing happens, better place is the trash. Good luck.
