Caution:
This information is confidential and may not be distributed. Only a qualified service person should
do the reprogramming.
After replacement/repair, the customer settings and also the region code may be lost.
Reprogramming will put the set back in the state in which it has left the factory, i.e. with the default settings
and the allowed region code.
Reprogramming will be done by way of the Remote Control.
Complete version matrix to be enter is
'PLAY 159 XXX XXX XX PLAY'
.
Do the following steps with the Remote Control:
1) Ensure no disc is loaded in the tray.
2) Set the Remote Control to
DISC
source.

5) Press
<PLAY>
again.
Caution: Wait for about 3 seconds for the set to reset to the required setting.
The TV screen will turn blue follow by a loud sound at the speaker output.
6) Disconnect mains to ensure proper reset.
How to check the version matrix and the software version number of the set:

Repair Hints
Figure 14
1) During repair it is possible to disconnect the ECO6 Tuner
Board completely unless the fault is suspected to be in
that area. This will not affect the performance of the rest
of the set.
2) The flex cables are very fragile, care should be taken not
to damage them during repair. After repair, be very sure
that the flex cables are inserted properly into the flex
sockets before encasing, otherwise faults may occurs.
