Phillips 15PF5121 Flat TV. Also Humax PVR-9150T
The screen is completely dark, but the sound is OK. I can also change channels. Just no picture.
I have unplugged the main for 15 minutes, and disconnected the Humax. When I reconnected the mains, the TV was dead, until I replugged the Humax and as before, the sound is there, but no picture.
Thank you very much for the help.
