Monitor turns on for three seconds and black screens
MY MONITOR WAS NOT LISTED ON THIS WEBSITE. The monitor im talking about is a Dell ST2310. Before I tampered with the guts of the monitor, it worked fine but one of the 2 backlights blew out so it was dim. So I proceeded to order the right backlights for the monitor, install them, and they work! The screen is now full on bright. And now anorthern problem arises, ever since I replaced the backlights the monitor turns on and stays on for about 3 seconds and then it blackscreens. The screen turns back on for 3 seconds if I unplug and replug the HDMI cable but it turns off again. I'm just looking for some things that could've gone wrong in the rebuild because it didn't do this before I took it apart.
