I just bought an LG E2040T PN 20 âMonitor. It was working about a month but then stopped displaying images. I went to the shop where I bought the monitor and they check it but it work in that shop and no problems were being detected. Then I bought it home again, but then the same problem struck again however my old CRT monitor worked well. Then I took the LG monitor and plugged it my friend’s house and it work out there too. Is this the problem with my electricity at home? Please help!
