Hi,

Display is,
ER320HQ, ER320HQ widx
UM.JE0AA.001
April 2018
After a few months of solid use the display has malfunctioned. Verified with other cables and computer input sources. The display would function then go erratic with the horizontal and vertical outputs appearing scrambled and sometimes completely scrambled display output, with random display of colors (nice art), and then the screen would go dark and become unresponsive (backlight stays on). After turning on/off or just letting it sit sometimes the display recovers. The issue is unpredictable and makes the monitor unusable. It is preferable to fix this issue if it is just a bad capacitor, chip or loose connection that can be desoldered/soldered replaced than to drop if off for recycling so soon.

ACER please provide a solution. It would be nice if you at least provided an email address where we could have a direct (out of warranty) response as you probably know what the issue is caused by so we know what best to do.

Thank you,
AF
