Are you having an issue with an iPhone display that is severely dim or dark? If it's powered on and you can hear sound and vibration it often makes when turning on but it still displays nothing, then you might be having a blown-out backlight. Bring the phone to our Midwood store for iPhone repair: we find the blown-out components and replace them after you approve the price.
Backlight complications range from the blown-out chipset and capacitors to damaged resistors and other circuit problems.
We start with a detailed diagnosis, tell you what failed and what the repair costs, and nothing is repaired without your yes.
Should you be having dark display defects, you're welcome to reach us through these channels.
The first sign of a defective backlight is the severely dim display. The defect can be confused with a display problem. To check it, power your cell phone and shine a flashlight on the screen. If you see a dim Apple logo then you have a backlight defect.
The iPhone models with LCD screens have backlights that assist in the display. OLED models have no separate backlight, so a dark OLED screen is a screen or board fault; we check which one during diagnostics.
Most of these faults occur as a result of inept screen swapping. If the battery is left connected during a screen swap, it often causes blowing of resistors on logic boards that eventually affect backlight function. We correct this by measuring the diode values of pins of the LCD connector using a voltmeter to identify defective resistors. Once we've identified a faulty resistor, we'll cover the board with a high-temperature resistance tape to protect other components and then heat the shielding cover.
We'll then remove the blown resistors indicated by the pin without diode values and swap them with new ones. Finally, we test the new resistors and refit the main board and check the display.
Sometimes the defect may arise from other faulty components on the board like capacitors. This too will be identified through a thorough examination and then repaired, as in our other iPhone motherboard repair work. If the backlight layer of the screen itself has failed, we replace the screen instead (see iPhone screen replacement).
Repairs come with a 30-day limited warranty.
You can bring the phone in as soon as you notice defects without delay since we're open daily, 10 AM to 7 PM.
Repair time depends on the fault; we tell you after diagnostics.
We also offer a projection of remedying costs before servicing to assist you in budgeting.
We charge iPhone backlight rectification depending on its model. The price is quoted after diagnostics. Diagnostics cost $99 and count toward the repair if you go ahead.

It may be dimming because of the reasons below
Of course, it can be substituted through expert servicing. On LCD models the backlight is part of the screen assembly, so a failed backlight layer is fixed with a new screen. If the fault is in the backlight circuit on the board, we repair the board. Diagnostics show which one it is.
Various causes can lead to this deficiency. The most common are:
