17ips72 Schematic Work May 2026

Working on this common power board found in many budget LED TVs. These are notorious for "bad quality" PCBs and weak solder joints.

Pins 5 and 6 connect to a small ceramic capacitor (typically 0.47µF to 1µF, rated >16V). If this capacitor is shorted or low capacitance, the high-side MOSFETs will not turn on properly, causing the motor to twitch but not spin. 17ips72 schematic work

Lenovo does not release schematics to the public. Here is the legal and practical reality: Working on this common power board found in

Once the board has its 400V, the schematic shows it splitting into two main paths: If this capacitor is shorted or low capacitance,

If you are looking at a repair log or schematic analysis of this board, here is why it stands out:

The 17IPS72 is a Switched-Mode Power Supply (SMPS) designed to convert high-voltage AC mains into stable DC rails for the TV's internal components. Key sections of the schematic include:
