I have a PS3 and a Panasonic TV with Viera Link connected. I used to be able to turn the TV on and off using the PS3. This feature stopped working however after I recently unplugged all the HDMI cables and the power from my TV to clean behind it. I plugged everything back as it was (PS3 HDMI cable into same HDMI input etc). Unfortunately, after this operation the PS3 can no longer turn on the TV.
I've tried resetting the PS3 and the TV to factory defaults. I've tried different variations of power cycling the TV and the PS3. I've tried other HDMI cables. I have other devices (chromecast switch) that are able to turn on the TV using the CEC protocol. I'm running out of ideas of how to fix this!
Any help is greatly appreciated!
