Since warranty is over, then I would suggest having it repaired at external 3rd party mobile repair shop, the cost of repair would be cheaper, as compared to Samsung service centre, where out-of-warranty and labour fees would be excluded from the screen replacement cost.
I am unable to find A73 screen replacement cost on Samsung Singapore's website.
As for 3rd party mobile repair shop, here is one reputable store:
https://www.mistermobile.com.sg/product/samsung-a73-lcd-replacement/U may consider any other options as well, as long as the repair cost is reasonable and able to replace ur LCD screen professionally.
Of course, if ur device is still under warranty, always go back to Samsung official repair centre, as repairs performed by external will void the warranty.
