I have a problem with a HITACHI TV model 50HAK6165 main 17MB170 panel VES500QNDP-2D-N43. When I power it on, the power on LED flashes 20 times and then stays solid. The screen remains backlit but is black, the operating system does not start. How can I restore the eMMC which is probably corrupted using the USB input?
AI: Have you already tried any USB recovery/update procedure on this TV? If yes, what files did you use, how did you format the USB stick, and did the LED behavior change during the attempt?
No
AI: Can you provide the exact sticker data from the mainboard/back cover (firmware/chassis/version codes), or the exact firmware package name you plan to flash for this 17MB170 + VES500QNDP-2D-N42 combination?
yes
