Internal Checks
Internal Liquid Contact Indicator
The iPhone 4 (CDMA model) contains one internal liquid contact indicator (LCI) on the shield
of the main board. If the LCI is activated (red), it indicates contact with liquid, which can cause
damage that is not covered under warranty and is not eligible for modular repair, but is eligible
for Out-of-Warranty (OOW) paid whole unit replacement.
Important: If an internal LCI is activated or corrosion is present, reassemble the device and do
not proceed with modular repair.
Missing Internal Parts
If there are missing internal components or parts, it is considered evidence of disassembly or
modication, which:
• is NOT covered under warranty
• MAY qualify for a paid repair.
For more information, see Apple Support article TS3756: iPhone and iPad: Handling service
requests when device has missing or modied parts.
