Want to find motherboard for 48HU8500

[twinexotica]

Does someone know where I can get the mainboard for this TV anywhere other than the crappy service center ?
My TV got busted (keeps on clicking) and Samsung told it was the motherboard and costs about $300 to fix !!
BTW the TV part no is BN41-02205b
And will this board work ?

And I know everyone upgrading these tvs, but I haven't watched a single 4k video on this ever since I bought it.
