This monitor has developed a fault that causes its display to blink on and off in rapid succession like a strobe light, i have tried all of the inputs at various refresh rates and resolutions, it even blinks on the pc's bios screen! Any help would be fantastic as this is a lovely monitor to use...
This sounds like the PSU in the monitor is on its way out, if the monitor has been on for a long time "months" or in a hot environment it reduces the life of the caps in the PSU. Let me know how you got on with it
