820-3115
I found burnt transistor or mosfet (3 pin chip) on dc jack on 820-2565 dc jack board.
I tested main board with another dc jack but same story. CPU core appear only for 1 seg at 1.12V
I compared all coils with another board 820-2879 and only found differen value at L7260. In faulty board I have 0.173 in diode mode. Red in ground
In working board I have 0.400 in diode mode. Anything more I can measure?
