Monitor turns on for three seconds and black screens

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.

@wayvekz sounds like your power board or your USB board is cutting of the power to the backlights. I'd disconnect the backlights and check to see if it works with half of the. You do want to try all inputs to see if it makes a difference. BTW this one uses LED backlights or CCFL. I have a guide that shows 2CCFL but just making sure we are on the same page. you also want to post some good images of your boards with your question. That will allow us to see what you see. Use this guide Adding images to an existing question for that.
