Hi all
This set seems to power up , with LED at front changing to GREEN , but no picture , or backlight , plus cannot set TV back to standby .
Suspecting main board issue .
Powered the backlights independently & they light up ok .
Disconnected HDD & powered , with same results .
Checked supplies at all the buck regulator outputs on main board & again seem ok .
Anyone have experience working on this model .
