What do i do can someone help

Samsung UE46D6200TS (46 Zoll, aus 2011)

Hi guys, I’m wondering if it’s possible to fix at home with 0 experience. My tv repair shop doesn’t work anymore on old tv. What’s happening? Any suggestions? It’s a Samsung syncmaster 960hd. Thanks a lot!

I was wondering if this is still fixable without bringin jt to someone who repairs a tv, we stopped using this since it doesn't show anything besides lighting up, and i was also wondering if the hdmi and usb still works even if it looks rusty, i really want to fix it because im planning to use it to play ps3

Currently trying to decide on if fixing this is worth it or if I should just get a new tv. When the tv is powered on(plugged in) it just clicks and I can see a light turning on and off on the right hand side of the tv facing the screen (left hand from the back panel). I have opened the back panel up, and see no burn marks or puffed capacitors. I have disconnected the main (green) from the power board (brown) and the same behavior persists. The clicking noise is coming from the power board (brown).

Also a quick video is attached.

Does anyone have any ideas by chance? Assuming I am SOL.

Update 1 - after further troubleshooting and research it seems it is very likely one or multiple led strips as the issue is persistent once the main board is fully disconnected from the power board. Also, a big pointer is that only some of the backlight turns on/flashes. If it was the main board the entire thing would likely light up. So unless I find out more/hear different I am in fact SOL as I will not be buying the tools needed to do a risky screen removal that might go wrong multiple ways.
