Understanding the core blocks of the schematic—the , the main MOSFET (Q850) , the secondary Schottky diode (D854) , and the backlight driver —is key to a successful fix. For DIYers, this board represents an excellent learning opportunity. With the right approach and a multimeter, what may seem like a dead monitor can often be brought back to life for a fraction of the cost of a new one.
: You can purchase tested, working boards from retailers like AliExpress Local Suppliers : In Russia, the board is listed on Yandex Market DIY Repair : If you have soldering skills, community forums like provide discussions on identifying burned SMD components. on the board or finding a step-by-step replacement guide for your specific monitor model?
Typically manufactured by TPV (Top Victory Electronics) for Dell.
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 Ilpi-354 V.a Schematic
If you are troubleshooting without a full schematic, check these high-traffic failure points:
The switching transistors in the inverter section can fail, blowing the main fuse or preventing the backlight from striking.
Inspect the solder joints around the inverter transformer and the CCFL connector pins. The high voltage and heat can cause the solder to crystallize and crack over time. Resoldering these joints often cures the problem. Safety Warnings Understanding the core blocks of the schematic—the ,
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").
The Ilpi-354 V.a Schematic typically consists of various sections, including:
For precise component values and trace paths, it is highly recommended to search for a dedicated "ILPI-354 V.a pdf" in DatasheetArchive . 5. Safety Warnings : You can purchase tested, working boards from
This usually indicates a backlight driver failure . Verify if you have ~17.5V at the input of the driver IC (pin 9) and check for a ~3V Enable (ENA) signal from the logic board.
Usually marked as C854 , this large capacitor holds roughly 310V-330V DC .
