These boards were removed from a samsung au8000 50" tv with a faulty lcd panel I've taken all the bits out I could including cables and boards, so of you have a tv with a fault these might be good for parts or might work as a swap if your tv has a bad power supply. The tv these were removed from had an intermittent lcd issue. I can't be certain these will fix your issue so please make sure to do all necessary checks before purchasing
