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.

Do you still see dim lighting when it turns off? Have you tried another hdmi cable or maybe another type like vga? Do you smell burning? Extra heat maybe? If not check your solder job. Maybe it shorting out. Heck, even try another power cable.. Find Schematics ans test voltage..maybe the backlight or receiving to high of voltage.. maybe even got the wrong or cheap backlight filters? Just helping with troubleshooting.

Did you try to troubleshoot your monitor? I have seen this problem very common in people. And the solution to this problem is also very simple.
