I've got a SONY BRAVIA KD43XG8096BU, it's developed this really strange qwerk where after turning the TV on it will boot up, load the the say main menu screen then turn straight off again. I have to then power it back up a second time for it to stay on. The issue also happens when I run a Google command "Google, Open Netflix on the TV" it will power up, then turn off. If I say the command again it will work.
I've tried resetting the TV to default, does the same thing... I don't know what else to try & fix it?
Here's a random one with my Sony TV: If I use the remote to power on, and withdraw the remote immediately from line-of-sight from IR, the receiver assumes I'm still holding down the power button and performs a shutdown or reset. Maybe that's what's happening to you too? It's stupid, I only use the remote on my Chromecast with Google TV now.
