Monitor won't turn on with power led not lighting up

[cracksnacksnap]

So my monitor one day just stopped displaying anything . It's a LG flat screen monitor . I've checked my comp hardware and everything is fine so it's the monitor but I don't have a fix for it 🙁

Thanks!!

If it uses an external power supply, Test the output for voltage. My local Staples and Bestbuy will check them for free.

use a flashlight see if the backlight went bad. if there no error blinking on the monitor see if there a hard reset that can be done on the unit. if not if the unit out of warranty google the model and error. see if a cap on one of the boards may have failed. a lot of times some units have bad caps and there are replacment caps and kits to fix units. if it not a cap issue look into the cost of service parts. (power,logic board). see if buying one or the other is less then a new monitor. if the unit under warranty rma it.
