Based on the alphanumeric structure, the most likely correct part number is MB-DIG43L-EUP.

Here is a technical paper/specification guide for the component identified, along with an explanation of the search term.

3.2 "Hot" Input Line Shortage

Pin 17 and 18 of the J2 connector are labeled "HOT IN" (High-Voltage Opto-Trigger Inputs). A common mistake is applying 24V DC to these pins when they actually expect 110V AC.

• Fix: Consult the manual’s voltage range table. For EUP 081802, "Hot" inputs require 90-140V AC. Use a step-down transformer or relay isolator.

2. Entertainment at Your Fingertips

Stay connected and entertained with features designed for modern lifestyles. Fix: Consult the manual’s voltage range table

• Infotainment System: A touchscreen (typically 10.25 inches) runs MBUX (Mercedes-Benz User Experience), integrating intuitive voice commands and gesture controls.
• Premium Audio Options: From the standard sound system to optional Burmester or Harman Kardon premium audio setups, enjoy studio-quality music, podcasts, or audiobooks.
• Multi-Connection Capabilities: Charge up to four devices via USB ports, and pair smartphones via Bluetooth, Apple CarPlay, or Android Auto for seamless music streaming, navigation, and hands-free calling.
• Rear Seat Entertainment: If equipped with a rear-seat screen, kids (or passengers) can stream movies, games, or music wirelessly from their devices.

Step 4: Isolate the Backlight

Unplug the LCD panel’s backlight connector (usually a small white 2-pin connector). Re-power the board. Does it still run hot?

• Yes (still hot): Problem on the main logic board (caps, regulator).
• No (cools down): Problem in the CCFL lamp or LED strip. Replace the LCD backlight.

7. Where to Find a Replacement MB DIG43L EUP 081802

If your board is beyond repair (burnt PCB or failed custom IC), your options are:

• eBay / AliExpress: Search the exact string MB DIG43L EUP 081802. Expect prices from $25 to $80 for used pulls.
• Electronics surplus warehouses (e.g., Mendelson’s, MPJA).
• Repair services – Search for “industrial LCD board repair” in your region. Many shops will re-cap and re-regulate your board for $40-$60.
• Harvest from identical scrap equipment – Look for the same monitor or terminal model on Craigslist or local auctions.

6. Preventing Future Overheating (Proactive Cooling Mods)

If you repair the board or find a replacement, implement these cooling improvements:

1. Add a heatsink – Use adhesive-backed 14x14mm aluminum heatsinks on any regulator running above 50°C.
2. Replace thermal paste – If the board has a power transistor bolted to a frame, clean off the old, crusty paste and apply fresh Arctic Silver or similar.
3. Improve airflow – If the unit is in a sealed enclosure, drill a small vent grid or install a 40mm 5V fan (powered from the board’s 5V rail).
4. Recap the board – Replace all electrolytic capacitors with 105°C high-frequency, low-ESR types (e.g., Panasonic FR or Nichicon HW series). This alone often eliminates overheating.
