I have ALWAYS black screen (for 1 -2 sec) bug when watching my HT computer. Bug for one time, max 2 times after I select the computer as source and after usually 10-30 secs from selection.
I am ALWAYS using RGB 4:4:4 instead of YCbCr as default HDMI protocol because of cyan screen bug of my flagship television.
I would like to see Philips more active to solve these bugs (52pfl9704 last firmware) other people in the community descrtibe them with other words since more 6 months...
Otherwise, I/we should call the service, more times,
while the television is covered from official warranty.
Hurry up Philips!
