Screen doesn't power on, flickers on and off, is it possible to repair
Hello!
The TV in question is actually the un55ks800df model, however ifixit wouldn’t let me select that so I figured this one is close enough. It is not curved and it is a UHD TV from 2017 I believe. Here is what happened:
I was watching it as usual a while back (I’ve been very busy and haven’t had time to fix this for a while) and for some reason all of a sudden the bottom of the screen turned green and then the rest of the screen and then the screen slowly faded out.
Ever since then, whenever you try to power it back on the screen will flicker on, flicker a little bit and then go back off, and then continually repeat the cycle. The Samsung logo in the bottom middle keeps flashing on and off with the screen as well. It won’t stop doing this and pushing the power button doesn’t seem to turn it off, I’ve had to unplug it to stop this cycling.
Any ideas as to what this could be and is it something that I, a moderately adept handy kinda guy who can solder and all that, can fix?
Appreciate all the help!

Hey so I’ve not opened the back of it up yet so I can’t say what is on the boards. I do have a video of what it is doing if that will help and I will get back to you once I open the back up.

Also I did a bit of googling with the model number and according to this ( https://www.tvpartshome.com/product/sams... ), the power supply/led board is BN44-00878A, though that site also says that the board number(s) is/are: L55E7_KSM , PSLF191E08A .
Let me know if that’s not enough info and I’ll crack it open and get a pic of the guts for ya. Thanks for taking the time to help out!
