This section uses a Pulse Width Modulation (PWM) controller IC to "switch" the high-voltage DC through a transformer. Common issues in this section often involve the main filter capacitor or the switching MOSFET.
and found across a massive fleet of budget-friendly, high-reliability Dell monitors, including the Dell E1916HV
A full-wave bridge rectifier converts AC voltage to pulsating DC, which is smoothed into roughly 310V–340V DC (on 220V grids) by a large electrolytic bulk capacitor (usually rated for 450V).
The is a power supply board primarily used in several legacy Dell monitors , including the Dell SE2216H Go to product viewer dialog for this item. , Go to product viewer dialog for this item. , and Ilpi-354 V.a Schematic
Regulated DC rails provided via a pin header to the main video processing board. Common Failure Points
Leaking or bloated electrolytic capacitors in the secondary stage.
The ILPI-354 power board is the central power supply module for several popular Dell monitor models, including the , E2216HV , SE2216H , SE2218 , E1916HV , and E2316HF . If you experience sudden blackouts, blinking screens, or complete power failure on any of these models, it is highly likely that the ILPI-354 power board is the culprit. This section uses a Pulse Width Modulation (PWM)
: It is frequently used for repairing monitors like the LG Flatron W2242S and Philips 220CW , where this specific board is the core power and inverter module.
The is a power supply board commonly used in Dell monitor models such as the SE2216H , SE2216HG , E2316H , and SE2218HV . While a full, high-resolution official schematic for this specific board version is rarely released by manufacturers, technicians often rely on component data and similar board layouts for repairs. Key Technical Details & Components
If the board is scorched beyond repair, you can find replacements on sites like AliExpress or eBay by searching for the or the Dell-specific part number 790JW1400601R00 . Are you seeing specific component damage? Tell me: The part number of the burnt component (e.g., R801, D202). The symptoms (e.g., "no power" vs "no backlight").
