Hi guys, they brought me a rcf 745 that does not turn on, I noticed that the ADAU processor was shorted, I changed it and now it turns on but the red limiter led blinks 7 times, I tried to change the eeprom too, ( as a test I took it from another rcf 312A module) but still the same defect, what can it be? I also tried to remove the 2 opamps U5 and U6 to exclude some disturbance but nothing ... what do you recommend?

Hey guys, I solved it ... the problem was a wrong soldering of the micro ADAU ... now everything works correctly.
I ask you a question ... can you recommend a programmer to be able to read and write the eeprom 24lc256? I have a GQ4X4 and a CH341a but they don't work with this eeprom ...
