Bright spots on LED TV, tried to fix second time..ended up damaging the cof connecter.
Though the fix is cheap (just apply super glue on reflectors), it isn’t reliable and while getting to the reflectors you might end up damaging other delicate parts of the TV.
If you are unsure, get it fixed up by a technician, who will simply replace the LED strips.
