Apple iPhone 6S no picture, no blacklight ?
If you have a problem with the iPhone 6S not showing picture without any signs of physical damage or you can see something on the screen but there is no backlight, this is probably backlight filter or backlight IC damaged on the logic board of your iPhone 6S.
This problem needs to be properly diagnosed before we do the job. First we disassemble your iPhone and check if this is actually the screen issue. After that we check for any water damage or physical damage to inside of the phone. Then, we confirm the condition of the backlight filter and the backlight IC. We replace them after we confirm that those are faulty.
Backlight filter and IC are very small components that need to be removed, then replaced and the work needs to be performed under the microscope, using hot air station and micro soldering equipment. After we replace it, it will bring your LCD display and its backlight back to normal.
Not every phone repair shop can do this job. In fact, there is only few placed in the UK. Our technicians are professionals with years of experience in micro soldering. You only pay for successful repair. To guarantee your satisfaction, we don’t try to reflow the logic board but we always replace the IC chip, using high quality micro soldering equipment.
