Does Louis got these: LP8549B1SP-03 and LP8548B1SQ-03?

Or anyone can recommend where to buy them? Only found them at L2 and Ali (from suppliers I do not know).

Thanks. I have already got a lot of scrap boards but only two of them had LED driver chip still on. Then I used one of them and tested the broken board with my testing screen and backlight came up. Then I put machine back together. In the rush I did not check for shorts after putting back original display (doh!) and backlight blew again. I took the last chip from my scrap boards and is also not working so now I just ordered some from Ali as I have enough other components on the donor boards. But thanks anyway.

I got display backlight working in this one. Received the backlight driver IC's from Ali and now I have backlight in the display. I don't know what broke it because the original display which I firstly assumed was shorted is not shorted.

I put it all back together just to find out that keyboard backlight also is missing. Any ideas?
