To everyone that has posted in this thread…You are definitely not alone! These HDMI problems have been going on for over a year now. I have seen all of the problems mentioned in this thread posted here many times before.
When you plug in the HDMI cable, the WD box tries to auto-negotiate with your TV to determine how to set up the video output. If you have a TV that is not compatible with this auto-negotiation, or if you have an older TV that does not support auto-negotiation, then you will have the problems that have been reported in this thread.
I have an older Plasma TV that does not support auto-negotiation. Every time I turn the WD box on the HDMI output is frequently set to a resolution that my TV does not support. I have to use the composite output to see the video in order to get to the WD setup. I set the output to 1080i,60 Hz and RGB Low, however the box does not remember these settings. The next time I power the box on, the same thing happens.
Also, while the WD box is just sitting there idling on the home screen, it will change the color space value all by itself resulting in a pink screen. It changes the color space from RGB Low to YCbCr all by itself! I have to go back in to the setup to change the color space back to RGB Low.
If the WD box would just remember the video settings that you set manually, instead of trying to auto-negotiate, most of the problems reported in this thread would disappear. I am hoping that WD will address this issue before abandoning firmware support on the Live/Live Plus.
