Doesn't start. Keyboard locked locked in eeprom | Eeprom blocked / when the monitor does not turn on and neither the blue standby LED is lit, it was probably turned off during the keyboard power with the keyboard blocked condition. Tsoundfore, you can try to call via the service remote control if the normal control also does not respond. If none of this works, the solution for me was to import a working board from China and copy the eeprom data. Bingo! I am making the data available For sale on the free market user on ml: arrudaedson97 | Rewrite eeprom 25x20xx ic501 | SNEGS |

On, the standby LED keeps flashing alternately between green and red and it doesn't go away | I checked the "open" LED bus, as I didn't disassemble the TV, only through the LED tester I could see that the LED circuit was open, that is, the TV acts as protection because tsound is no consumption/load on the LED bus. with an external bus with 6 volt LEDs (3 strips of 7 6 volt LEDs) I simulated the consumption on the TV and then the TV started working and I could see the image with a flashlight.... | LED panel defect, I didn't find it in any supplier. The LED panel of this TV is American Hisense, I found it on Aliexpress, follow the link right after (on the body of the rulers it is described: hd425y1u71-t0l2 2020092801 svh430ag9): pt aliexpress | MIGUELTV |
