How to change the display and screen for the Samsung galaxy A30.

@aravind7991 Just to check this, Power-on the phone and check the power-on sound or motor Vibration. Sound or Vibration is ok? If the answer is yes, replace the display assembly.

If it is not, you will have to check the video circuitry on your PCB’s according to this flow-sheet

Here is the board view Samsung A30 Boardview. Use the search function of the PDF reader you are using, to find the components etc.

I still think your display is the prime suspect ;-)

Since iFixit does not yet have a specific guide for how to replace the display use teh guide from here It was written in French so use a browser that does the translating for you, if needed.

Replacement screens are readily available at many online places.

While you work on your phone, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
