How to Copy NVM Data to/from USB
When copying data to and from a USB memory stick, the folder
“repair” is used. When inserting an empty USB memory stick,
and downloading data to the stick, the TV will create this folder.
When sending data from a USB memory stick to a TV, the
intended data must be available in the “repair” folder.
Note that when copying EDID data to the TV, all necessary
EDID files must be in this folder.

Fault Finding and Repair Tips
Note:
•
It is assumed that the components are mounted correctly
with correct values and no bad solder joints.
•
Before any fault finding actions, check if the correct options
are set.
5.5.1
Unstable Picture via HDMI input
Check if HDMI EDID data is properly programmed.
5.5.2
No Picture via HDMI input
Check if HDCP key is valid. This can be done in CSM.
5.5.3
TV Will Not Start-up from Stand-by
Possible Stand-by Controller failure. Re-flash the software.
5.5.4
Audio Amplifier
The Class D-IC U606 has a powerpad for cooling. When the IC
is replaced it must be ensured that the powerpad is very well
pushed to the PWB while the solder is still liquid. This is needed
to insure that the cooling is guaranteed, otherwise the Class
D-IC could break down in short time.
5.5.5
Loudspeakers
Make sure that the volume is set to minimum during
disconnecting the speakers in the ON-state of the TV. The
audio amplifier can be damaged by disconnecting the speakers
during ON-state of the set!
