Repair costs can exceed what a new display costs. Get estimates.
Think of monitors as consumables, almost like printer ink (well, in BIG tanks). They can seldom be repaired.
It appears as if your backlighting is malfunctioning. It is usually quicker and easier, and nearly as cheap (or cheaper), to get a new one rather than trying to find someone to fix it.
Many monitors have a surprisingly short lifespan, although generally speaking Samsungs are not as bad as most. I have found ViewSonic monitors to be the most durable.
Many backlighting issues can be fixed by replacing the capacitors on the main board inside the monitor. That just requires a little time and a little facility with a soldering iron.
Personally, I kind of enjoy a project like this a coupla times a year. But, as others have said, 27" monitors are pretty cheap, these days. Up to you to decide if it's worth an hour or two of your time to fix it.
First, search for your particular model of monitor along with the word "backlight" or, in your case, "flickering." Chances are you'll find a few forum posts of people having the same issue. They'll be able to tell you if it's capacitors, the inverter, or the LCD tubes.
If it's capacitors, you can do a search for your model of monitor and "cap kit." I got one on Amazon for about $12. I forget what I spent on some fluorescent tubes. Pretty sure they were cheap, too.
If it's the inverter, that usually doesn't involve soldering, but they're more expensive. One I got for a laptop screen was about $70. Probably not the inverter. I think those are only used to get the tubes started, and then it's not used, anymore.
Getting the cover off the monitor is often the most time consuming part, for me. The plastic frame is hooked on notches at the corners of the frame, and I find it very difficult to get the first corner free. It really feels like I'm going to break the thing.
Use care in making sure which capacitor goes where. Draw a diagram, or take a few pictures with your phone, and mark them up. Be careful getting the old capacitors out. You don't want to rip the "pad" off the board that the solder sticks to around the holes. I did that once, and was able to scrape a half inch of the covering off the trace and solder a spare bit of excess wire to get the connection back to that leg of the capacitor.
