Hello repairer friends
I received this TV for a customer, once turned on, no indicator, no backlight, no optical indicator
The R5F100GEA standby micom responds to the button and the remote control. The micom starts the main microprocessor power supplies, there is access to SPI MX25L3205 and eMMC (oscilloscope measurements). Access to the eMMC is too short for full firmware loading.
I took the eMMC apart to read and compare it with the contents of another eMMC found on a repair forum. The reading of my memory is consistent with that of comparison, whether by sector or content.
I did the same for the SPI and EEPROM.
I reprogrammed the memories with the recovery content from the friend's site, and the result is the same. I still have limited access to the eMMC from the microprocessor.
Do you have any ideas to share with me? THANKS
