Hi guys,

I've been living with this for the last 4 years and have just found a fix.

The problem is after switching to the media PC input the Tv switches back to the tbox input after a few seconds or minutes or sometimes never. Quite odd and took a while to figure out it was the tbox. The workaround was turning the tbox to standby.

Until just now, I figured it was the CEC protocol but didn't want to turn it off as the Tv and home theatre talk together using Bravia sync.

The solution was to use a push pin to bend pin 13 up on one end of the hdmi cable. This is the cec pin and will essentially shut the box up.

Anyway I came across a few locked post so thought I'd spread the news.
