: Capacitors mounted near heat sinks are prone to drying out or bulging due to heat exposure from MOSFETs or transistors.

The Wannien 101V0 circuit is designed to step down a 12-15V DC input to regulated outputs. In monitor applications, it also integrates inverter circuitry for the display backlight. 12-15V DC. wannien 101v0 power supply schematic repack

Official schematics for Wan Nien boards can be difficult to find. You can often find them in service manuals for the specific device it powers (e.g., specific HP or ViewSonic monitors) or via specialty electronics forums like for the capacitors or finding the specific monitor model this board belongs to? 12-15V DC
The primary hurdle in the 101V0 "repack" (the process of refurbishing or redesigning the internals) is the scarcity of official schematics. Most repair stories begin on community forums or expert Q&A sites like JustAnswer
