Hi Jasley,

It's hard to find mainboard for LED TV. You can try the local authorized service center and also from online website like aliexpress and ebay.

In reply to mahmoud_tajpour.

Glad it was an helpful repair Mahmoud_tajpour. Indeed the RDS(on) value can always be found in the Datasheets and tells us how much DC Power we lose in the Mosfet Resistance when source and Drain are closed. And we also can calculate and measure what voltage we will lose over the RDS(on) when it conducts the DC Current.

I found 10 pieces of them radial for only $1.99 US dollar on Ebay.
I hope that you are able to pay with Paypal. Look here:

I will add your email address to my contact persons list, if that's okay.
Good luck with fixing your Monitor!
