Hi, I'm in Hong Kong (PAL). I just powered up my Pi 3 model B and it is not giving any HDMI output. I have tried the following:
1) replacing HDMI cable just in case.
2) Forced to safemode using hdmi_safe=1 in config.txt (Raspian on USB thumbdrive). No luck.
3) Forced to VGA output hdmi_group=2 && hdmi_mode=4. No luck.
What else should I try?
