Manufacturer: Vestel (OEM board used in various Hitachi TVs) Flash Memory: Houses an MX25L1606E SPI flash (25L1606) that stores firmware
Firmware: Multiple firmware versions exist—look for markings like “v3.2.9r” or “v3.6.3j” on the board label Common Issues:
Bootlooping, blank screen after logo, or power cycling often due to:
Mismatched firmware or corrupted bootloader.
Wrong power supply unit (PSU) variant for the specific LED panel.
Firmware-flashing errors, especially related to the MBOOT section
Two PSU variants are used with this mainboard:
17IPS71 PSU → used with VES420UNDL‑2D‑N03 panel (36 LEDs)
17IPS20 PSU → used with VES420UNDL‑N01 panel (48 LEDs)
Flashing firmware via USB can brick the board if done improperly—especially if overwriting MBOOT section without matching version
Users have recovered boards by swapping SPI flash chips or cross-flashing—but compatibility hangs on correct firmware-image match .
