Lg 32 lf515a tf motherboard

Likely Mainboard Model

No direct service manual for the 32LF515A, but it’s very similar to the 32LF510B/32LF510U TVs. Those use the EAX66xxxx mainboards—specifically:

• 32LF510B uses EAX66453203 (with CPU LGE2136, EEPROM AT24C256, SPI Flash MX25L8035E)

• 32LF510U uses EAX66408104, same chipsets

So, your 32LF515A most likely shares this board series (EAX6640xxx) and uses the same components (CPU LGE2136, MX25L8035E flash, DT1641AS PWM LED driver). KitBazar even lists a specific “32LF515A LG motherboard” — a used, tested, original unit

🔧 Main Features & Components

• CPU: LGE2136

• Flash Memory: SPI Flash (MX25L8035E) & EEPROM (AT24C256)

• LED Backlight Driver: DT1641AS (integrated into mainboard)

• Tuner: Likely TDJS‑G101D or similar

• Panel Resolution: 1366×768 (HD‑Ready), LVDS interface

• External Power Supply: ~19 V adapter (e.g. LCAP16B‑E)

Based on the similar models:

• Board part number: EAX6640xxx (e.g., EAX66408104 or EAX66453203)

• Shielded EEPROM and flash chips for firmware and config

• LVDS panel connector, standard HDMI/USB/audio ports

💡 Repair or Replacement Tips

• Replacement boards labeled 32LF515A LG motherboard are available (used/refurbished)

• Ensure compatibility by matching the EAX board number (main PCB) and EBT sticker number (full board assembly) — they often must align, though minor variations across similar models (like 510B/U/A) usually work

• For a “new” board, you may need a service remote to transfer settings (serial, region, tuner config). A used board might already contain necessary data

• When installing, take care with ribbon connectors and thermal pads (common advice from TV repair pros)
