This is the power board Samsung QE50Q60TAUI, taken from a TV with a panel fault. Please note that ebay does not allow personal sellers to combine postage - giant scam if you ask me but I am forced to use their "simple" delivery.
The Samsung QE50Q60TAUI Power Board (LED PCB) BN44-01058A would be best fit in a professional or office setting where high-quality and reliable power boards are needed for large LED TVs.
