LG LP156WH4 panel EDID image, TL type with B1 revision, sized 256 bytes. The record contains the manufacturer code, product ID, supported timings and checksum that the laptop reads over DDC at startup. Writing this dump back to the panel EEPROM with a programmer can bring back a screen that is shown as an unknown device or stays dark. Different revisions of the same model may carry different timing data, so match B1 on the label and back up the chip first.
