Does not the picture of the HDMI signal input to HDMI1 go out?
MINI AV_UNIT:
Is the HOT_PLUG detection function of pin (19) of a HDMI terminal
(CN502) normal?
Are EDID data pin (6)(SCL) of IC U503 (EEPROM), pin (5)(SDA)
accessed, and is it read from pin (15), pin (16) of a HDMI
terminal(CN502)?
Is TMDS signal input into pin(63, 62)/RX2-2±,(60, 59)/RX2-1±, (57,
56)/RX2-0±, (54, 53)/RX2-C± of IC U501?
Is TMDS signal output from pin(17, 18)/ 2±,(20, 21)/ 1±, (23, 24)/ 0±,
(26, 27)/ C± of IC U501?
Refer to "The picture doesn't appear in all modes."
