Title says it all.
Disconnected all AV and HDMI wires from TV and discharged any remains by holding power button. connected everything then returned tv to factory settings and turned off HDMI controls.
I did what the username: FrankieViturello said.
This is by far the only solution I saw which I thought would have worked/ or understood.
Please help me, I just really want to use this bravia as a monitor.
Please remember, I can't open my pc using the Sony Bravia so I can't troubleshoot in there.
I mean I can't adjust display setting or screen resolutions because it never passes the black screen with "No Signal" sign at the bottom.
