RK3399 HDMI无显示

ubuntu固件。显示器无显示，已排除显示器和线的原因。
插拔HDMI线，信息如下：
dwhdmi-rockchip ff940000.hdmi: failed to get edid
dwhdmi-rockchip ff940000.hdmi: failed to get edid
rockchip-vop ff900000.vop: Update mode to 1280x720p0, type: 11
dwhdmi-rockchip ff940000.hdmi: PHY failed to power down
dwhdmi-rockchip ff940000.hdmi: PHY failed to power down
问题的原因是什么，怎么确定是否是硬件问题？
