Samsung un55ks8000 turns on but black/gray image power light blinks 7

My Samsung un55ks8000fxzc started having this problem where when I turn on the tv all I see is a grayed out image and the red power lights stays blinking 7 times. Then it power cycles and keeps repeating the same steps.

Any idea what it could be?

So I was able to get the TV to turn on and return to working order by taping 3 of the lines on the ribbon cable inside the TV. I followed instructions on a video online. Right now everything is working but I just want to know if this fix will stay and if there is something more permanent like replacing a part which I can do . Any info would be appreciated
