My screen is constantly flickering
I have a video if this will help:
Is this an LCD problem or is it a fixable issue in the hardware somewhere?

That TV looks like the model I had that has the notorious bad cap issue. My TV was doing something similar until it wouldnt boot anymore. Luckily for me, Samsung had a class action suit that extended the warranty to one repair. A tech showed up to my house and replaced the caps that were on the power supply. My TV was purchased in 2008 and it's still running strong.
