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 |
