Locate the 8-pin SPI Flash storage chip adjacent to the processor. Measure Pin 8 ( VCCcap V sub cap C cap C end-sub ) to verify it is receiving a stable 3.3V supply.

The DS80249 family of printed circuit boards (PCBs) is designed to power 4-channel and 8-channel standard definition and Turbo HD DVRs. It features a highly integrated architecture relying on a central system-on-chip (SoC), a Real-Time Clock (RTC) circuit, multiple voltage regulators (often in the Powers the hard drive logic boards and the onboard USB ports

Check continuity on SCL/SDA lines and ensure +5V pin out on HDMI port is active.

The DS8024 is an analog front-end for smart card readers, serving as a pin-for-pin replacement for the NXP TDA8024. It is commonly used in ISO 7816, EMV, and GSM applications. The DS80249 family of printed circuit boards (PCBs)
