My motherboard is damaged

Hi Gemy, looks like your Samsung Galaxy A53 5G now has a faulty motherboard because of a faulty technician. That is why I say that always give your valuables to a trust worthy repair centre. However, let's come back to the question. Motherboards are indeed expensive, and that's all because of there complexity in the functioning of the mobile. I am very unfortunately saying that there is no other option rather than replacing the motherboard, Here is a website I found where you can buy your motherboard for your Samsung Galaxy A53 5G. THE WEBSITE LINK (CLICK ME). However I again say that the trust issue occurs again, I have mentioned this website in iFixit but it does not mean that it is trust worthy, you might need to double check the site.

At last, I would say that PROCEED WITH CAUTION, as even you may go into the same problem again while putting your motherboard into your mobile. Motherboard are indeed very complex and hence are in need to be handled with care. Thank you for reading and bye.
