I
have a HP 22xi Pavilion led monitor. It is about a year old and no warranty left. It started going to a black screen when in use. I have to uplug the monitor to get the display to show. the power light stays on, but will not turn it off. I saw a few ppl having the same issue, with no success in getting this resolved. I have tried the external monitor on another laptop and have the same issue. I have replaced the power AC adapter and also downloaded the drivers for the monitor. this is very frustrating. I have tried to reset to factory setting and nothing changes. It will work for a while, then all of a sudden go to black screen and I have to unplug it from the back. Please assist..
