So I dropped my phone and my screen was working but it had really bad crack, it did not have any dead pixels but after a day the screen went full black, my question is can i just replace polarizer and should then the phone work or is it damaged and i need to buy a new lcd now? How to check that?

Well since you now have a black screen, the answer should be pretty obvious. You need to buy a new screen. The S10 plus uses OLED panels and whenever you break the screen whether it’s just the glass or you get a black screen, the only way to repair it is to replace the screen. OLED is very thin and fragile which just makes it difficult to repair.
这个答案有帮助吗？
Hi @dominik7111 ,
To add to the answer here's the ifixit 三星 Galaxy S10+ 屏幕更换 guide that may help.
So i can not just replace one part of the screen? Because i was wondering how it happend that it works one day and then goes complitly black and it havent got any dead pixels
yes you can't replace only certain parts of OLED screens and as a repair shop owner and technician, I speak from experience. The reason why it stopped working was because the OLED panel is fragile. When you cracked the glass that protects it, tiny shards of glass damaged it. Ever scenario is different. In some cases, people damage the OLED while the glass is completely unharmed.
What if the screen itself the pixels are all there and working fine but the top layer is cracked can the oled be saved
