Before we discuss the fix, we must understand the hardware. The is a proprietary microcontroller-driven scaling board, often found in: Here is how to access and "fix" your setup
Older service modes (like those on Samsung or LG TVs) could be exited by unplugging the unit for 10 minutes. The hdvx9as v41, however, writes a persistent flag to the onboard EEPROM (address 0xA0 on the SMBus). This flag tells the bootloader: “Do not load user firmware—stay in diagnostics.”
