Problem description
The Device turns on but it has no image.
Symptoms
- Device boots but no image is displayed
Solution
The no image problem can have 2 causes a bad display or a motherboard problem.
Diagnostic Steps
The first thing to do is to always rule out bad parts, so first try a new display on the phone if it works great all that is need is a screen replacement.
If even with a new display the phone is unable to display any image the problem is on the motherboard.
Start by inspecting the FPC connector for any liquid or physical damage.
If everything is fine take diode readings of the display FPC and compare them with the image bellow.
If the diode readings you took are ok next thing to check is if the voltages need to display image are present.
- PP5V7_LCM_AVDDH_CONN
- PN5V7_LCM_MESON_AVDDN_CONN
- PP1V8_LCM_CONN
- PP5V7_MESON_AVDDH_CONN
These voltages can be measured here and only show up with the device turned on.
