Monitor: Dell ST2421L

 
Hello!
 
I am having a minor lighting issue with my monitor. It affects only a small section of the screen as seen in the photo below. There is a shadowy area where there is very little lighting coverage on the screen relative to the surrounding screen. The light is restored intermittently on some startups, but only temporarily, and not commonly!
 

Is this something worth fixing, or should I just donate it and replace?

 

Thank you all very much for reading my silly problem, and hopefully someone has some insight!

 

- Adam

It looks like a segment of the bottom LED backlight is not working. Generally a backlight is an integral part of the LCD panel and when faulty wouldn't be considered a repair prospect. Someone with technical ability could possibly attempt a repair.

that's exactly what's wrong.  myself i would repair it but im a component level repair tech.  and it's a little processes to fix it.  you have to pull it apart and depending how it's made sometime the led's are easy to get to sometimes they are a bottom layer of the LCD panel that has to be disassembled to be able to get to it.   it's not cost effective to take it to a repair shop, cheaper to replace it with "Newer Bigger Better Cheaper"

Thank you both. Based on what you've said, I'm not in a position to fix this, especially being the monitor's age and value. I appreciate you taking the time!
