    >>21598892 I measured around 27v for VGH and -5v for VGL. I think it's a firmware problem not a hardware one.

Topic summary

A SABA43LED472RSW television with chassis 17MB97 and panel VES430QNDL-2D-N12 experienced a failure to power on, indicated by a blinking red LED and no remote response. After attempting a USB flash memory software update using files including mb97_en.bin, RomBoot.bin, PM51.bin, and usb_auto_update_D7L.txt, the TV powered on but displayed a bluish screen without image data, though it responded to the remote control. The original firmware and EEPROM were backed up prior to the update. The issue suggests firmware corruption or incompatibility affecting the NAND flash memory, requiring the correct USB NAND firmware version compatible with the specified chassis and panel to restore full functionality.
