In this photo, the unknown testpoint with 3 question marks over the text '''RY''' and located in the middle of a wide trace is '''3.3V_EVER_A''' (connected to pin 8 of voltage regulator '''mitsumi 463A''') | |||

(as you can see, all JTAG points are voltage active on a standby DECR. we need now to verify on a Test Proto if it's the same.) | |||
