iPhone 5 low resolution and blur image in every lcd
I have a customers iPhone 5 that dropped from his hand. When I received the phone I thought it was only the LCD that need replacement, I put other LCD but still the phone has low quality image, low resolution and blur image. I replace the LCD again but still the same, I test the LCDs in other iPhone 5 and working great. I checked the FPC connector and has no damage. Can you please help me, what do you think is the problem? Is there any damage IC? Any damage resistor? Where I suppose to look?
Please take a look at this photos
i inspected the motherboard with the microscope and i find one missing part. Please see the photos and advise me what to do
This missing part seems to be the Capacitor C440. Do you think this cause the problem? How can i fix this? Is it neccesary to find the same capacitor? Is this capacitor polarized or i can install it in any direction?
Thanks for your help!!!
