Verify if the RF ICs are receiving their required operational voltages from the PMIC. The schematic outlines the signal path from the antenna switch to the transceiver, helping you spot cracked filters or bad couplers.
Always verify your specific model number (e.g., Vivo 1814, 1815, or V1818A/T) before applying hardware solutions, as component placements differ between Qualcomm and MediaTek variants.

Ensure 5V reaches the Over-Voltage Protection (OVP) IC. If 5V enters the OVP chip but does not exit it, the OVP IC is faulty and must be bypassed or replaced. If it exits safely, trace it directly into the Charging IC (often integrated or secondary PMIC) to check the VBAT output rail. 4. Network / No Service Issues
Mobile manufacturers often revise motherboard layouts to improve production yields or address manufacturing defects. A "new" or updated schematic ensures you have the latest layout (e.g., changes between the Snapdragon 439 and Helio P22 variants, though SDM439 is more common, as shown in eBay product descriptions ). Verify if the RF ICs are receiving their
Open the schematic and look for the VBUS 5V line coming from the sub-board/flex cable.
Wear an anti-static wrist strap and use an ESD-safe mat to prevent static electricity from frying highly sensitive CMOS data lines. Conclusion : Handles the Micro-USB port and fast charging signals
