A TDT channel is no longer displayed
A specific channel is no longer displayed in my Philips 47PFL4007H/12 TV. Screen remains black and a message is displayed: "Unsupported video. format". I watched this channel perfectly so far. I noticed that a little key-shapped icon appears next to the channel name in the channel list, i don`t know if it is related to the problem.
I didnīt change any adjustment.
All my neighbors watch the channel smoothly.
I tried to tune channels again, but this did not solve the problem.
Any help will be appreciated.
