Display is not visible in realme x7 max

  • The phone vibrates when charging and when the power button is pressed, indicating the motherboard is functioning.
  • The display remains completely black, even after trying new display combos, which rules out a faulty screen.
  • The issue started after the phone was left under direct sunlight for some time, which likely caused overheating.

    Based on the symptoms, the most probable causes are:
    • Display IC failure
    • Display-related circuit or PMIC issue on the motherboard
  • Can the Display IC of my Realme X7 Max be repaired or replaced at home?

Unless you have a hot air workstation, including thermal measurement instruments, the general answer is no, this is not something us DIYers can accomplish at home. Microsoldering is a fairly specialized area of expertise and requires training and the proper equipment to do correctly. I've been working in the electronics field for over 40 years and consider myself above average with regard to soldering skills, but replacing a BGA component is not something I feel competent to attempt.

As much as I'd love to encourage your own repair efforts, at this point I have to admit that some jobs are best left to the professionals. A botched attempt at chip replacement can easily end up rendering the circuit board itself damaged and unrepairable.
