I have a Sony Kf-50we610 tv which a few days ago I started to turn off and turn on cyclically. The image and sound are turned off for 30 seconds, after which the image is first turned on and a few seconds later the sound, so it remains 1 minute and 30 seconds after which it turns off again for 30 seconds, this is done indefinitely. The TV does not really turn off, the screen darkens and loses the volume because the LED is always on green and if a channel change is made using the remote control during the screen off period to recover the image This has been done. I explain myself: if on turning off I was on channel 4 fox sports and using the remote control I change to channel 5 espn depotes any one returns the image and the volume is actually on channel 5. Please if anyone can help me I will be very grateful.
