A relative got a pasma LG tv, roughy 2 months ago. They also got a zinwell 620HD.
Within 6 hours it crapped out with blue screen on picture through HDMI, but sound through HDMI fine.
Tested zinwell on my tv all fine, Rang LG and as TV was less then week old replaced TV
It has gone fine for about 2 months and now on the new tv exactly same thing has happened again, and again znwell works fine on my tv.
Guessing it's HDCP failure as I know zinwell outputs blue screen when it fails. If I'm right so much for HDCP not inconviencing the legitimate user.
Repairer picking it up Monday, and if no comunication error bringing a loan TV.
Not impressive that same faults shown up in short time on two brand new tvs.
