Redmi 14C MIC SPK EAR
This section covers microphone, speaker, and earpiece circuits.
If mic is not recording voice or speaker sound is low, schematic helps locate audio IC connections and signal paths.
Most audio problems are caused by line damage or faulty audio components.
Redmi 14C NETWORK
Network section includes RF circuits, antenna paths, and signal processing components.
No service or weak signal issues can be diagnosed using the schematic diagram.
It helps identify antenna switches, filters, and RF IC connections.
Redmi 14C NFC
NFC circuit handles contactless communication features.
If NFC is not working, schematic helps locate NFC controller, antenna connection, and power lines.
NFC problems are often related to antenna disconnection or missing voltage.
Redmi 14C ON OFF VOL
Power and volume key lines are critical for device operation.
If Redmi 14C does not power on or volume keys are not responding, schematic diagram helps trace key signal lines to the CPU.
Broken key lines or damaged resistors are common causes.

Redmi 14C RESISTANCE VALUE ON PAD
Resistance value on pad information is very useful for troubleshooting missing components.
By checking resistance values, technicians can confirm whether a line is short or open.
This section is extremely helpful in water-damaged or physically damaged boards.
Redmi 14C SD CARD
SD card circuit handles external storage detection and data communication.
If SD card is not detected, schematic helps trace power and data lines from SD connector to CPU.
Connector damage is a common issue in this section.
Redmi 14C SIM CARD
SIM card section includes SIM power, clock, reset, and data lines.
No SIM detected or invalid SIM problems can be solved using schematic tracing.
SIM IC and connector play a key role in proper SIM functionality.
Redmi 14C SUB BOARD
Sub board contains charging connector, mic, and sometimes antenna connections.
If charging or mic issues persist after replacement, schematic helps trace connection lines between sub board and main board.
Flex cable continuity is very important here.
Redmi 14C TOUCHSCREEN
Touchscreen circuit handles touch input signals and power lines.
If touch is not responding or partially working, schematic diagram helps locate touch IC and signal routing.
Most touch problems are related to connector or signal line issues.
Redmi 14C WIFI BT GPS
WiFi, Bluetooth, and GPS circuits are closely linked with RF and power sections.
If WiFi is not turning on or GPS signal is weak, schematic helps trace enable lines and power supply.
These issues are often caused by missing voltage or antenna problems.
