Ya-4a194v-0 Motherboard Schematic [hot]

Generated by the main Power Management IC (PMIC). 1.35V/1.5V DDR3: Memory power supply. 1.05V/0.9V: Processor and chipset core voltages. B. Common Failure Points

: Boards may be interchangeable with parts labeled as "TMT YAML 19 94V-0" in certain ecosystems. ASUS X200MA-KX265D_YA-4A1 94V-0 E114139 BIOS

Look for a string starting with "DA0..." or "LA-..."

: To find the exact schematic, look for a secondary silk-screened code like DA0ZRCMB6C0 (Quanta ZRC) or something similar. Technical Architecture Overview

Often printed in white silk-screen on the PCB: "TMT YA-4A1 94V-0 E114139".

If you measure 0V, check the enable ( EN ) signals going into the IC from the Super I/O chip. Step 3: Check for Short Circuits to Ground
