Could a failing Main Logic Board cause the SONY XPERIA 1 V to have symptom: Overheating Camera Recording?

The Snapdragon 8 Gen 2 SoC and Image Signal Processor (ISP) are integrated into the main logic board; this component handles the data-intensive task of 4K 120fps encoding which generates the bulk of the device's thermal load. If the silicon has a higher-than-average leakage current or a defective thermal bond to the heat spreader, the board must be replaced to restore thermal efficiency.

Could a failing Internal Graphite Thermal Sheet cause the SONY XPERIA 1 V to have symptom: Overheating Camera Recording?

This graphite composite is responsible for the lateral dissipation of heat from the SoC across the device's chassis. If the sheet is delaminated or has suffered from air gap intrusion due to mechanical stress, it will fail to conduct heat to the frame, causing the SoC to reach its thermal trip-point prematurely.

Could a failing Xperia Stream Cooling Fan/Case cause the SONY XPERIA 1 V to have symptom: Overheating Camera Recording?

Sony specifically developed this active cooling accessory to resolve the thermodynamic bottleneck of the Xperia 1 series. It uses forced convection to lower the surface temperature of the back panel, allowing the internal passive cooling system to maintain a higher delta-T and prevent software-based thermal throttling during high-resolution recording.

What is the most likely root cause for a SONY XPERIA 1 V with symptom: Overheating Camera Recording?

System Nominal

Recording in 4K at 120fps requires massive computational throughput from the ISP and CPU, generating heat faster than the slim, glass-backed chassis can dissipate it into the ambient air. The 'overheating' warning is a programmed safety feature of the Android OS and Sony's firmware to protect the lithium-ion battery from thermal degradation and the SoC from structural damage.

NO REPAIR ACTION REQUIRED. PHYSICS CHECK CONFIRMED.
