All ICs and many other semi-conductors are
susceptible to electrostatic discharges (ESD).
Careless handling during repair can reduce life
drastically.
When repairing, make sure that you are
connected with the same potential as the mass
of the set via a wrist wrap with resistance.
Keep components and tools also at this
potential.

Tous les IC et beaucoup d’autres
semi-conducteurs sont sensibles aux
décharges statiques (ESD).
Leur longévité pourrait être considérablement
écourtée par le fait qu’aucune précaution n’est
prise à leur manipulation.
Lors de réparations, s’assurer de bien être relié
au même potentiel que la masse de l’appareil et
enfiler le bracelet serti d’une résistance de
sécurité.
Veiller à ce que les composants ainsi que les
outils que l’on utilise soient également à ce
potentiel.

WARNUNG

Alle ICs und viele andere Halbleiter sind
empfindlich gegenüber elektrostatischen
Entladungen (ESD).
Unsorgfältige Behandlung im Reparaturfall kan
die Lebensdauer drastisch reduzieren.
Veranlassen Sie, dass Sie im Reparaturfall über
ein Pulsarmband mit Widerstand verbunden
sind mit dem gleichen Potential wie die Masse
des Gerätes.
Bauteile und Hilfsmittel auch auf dieses gleiche
Potential halten.

NL

Alle IC’s en vele andere halfgeleiders zijn
gevoelig voor electrostatische ontladingen
(ESD).
Onzorgvuldig behandelen tijdens reparatie kan
de levensduur drastisch doen verminderen.
Zorg ervoor dat u tijdens reparatie via een
polsband met weerstand verbonden bent met
hetzelfde potentiaal als de massa van het
apparaat.
Houd componenten en hulpmiddelen ook op
ditzelfde potentiaal.

Tutti IC e parecchi semi-conduttori sono
sensibili alle scariche statiche (ESD).
La loro longevità potrebbe essere fortemente
ridatta in caso di non osservazione della più
grande cauzione alla loro manipolazione.
Durante le riparazioni occorre quindi essere
collegato allo stesso potenziale che quello della
massa dell’apparecchio tramite un braccialetto
a resistenza.
Assicurarsi che i componenti e anche gli utensili
con quali si lavora siano anche a questo
potenziale.

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.

3) Press

<PLAY>

followed by numerical keys

<1> <5> <9>

Remark: Top left hand corner of the TV screen will display "

Remark: Nothing will be displayed on the TV screen for all these 8 digits that you have pressed.

for LX7100SA/22 :

<2> <2> <2> <0> <3> <0> <0> <8>

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:

1) Power up the set and select

DISC

source.

2) Press

<SYSTEM MENU>

on the Remote Control to enter the User Preference Manual (UPM),

follow by pressing the following key:

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.

DVD Dealer Test is used to check the flash RAM, the SDRAM,
the DRAM, the NVRAM and the I2C communication.

When all the tests are passed, display shows "ALL TEST PASS".
If at least one of the test fails, display shows "ALL TEST FAIL".

DVD Player Test is used to start several DVD specific tests.
At the end of the test, an error code "aa-bbb cccc" (see Step15) will be
shown that indicates which module(s) failed.

** User has to give a confirmation by triggering one of the following:

- If the test is OK, press "PLAY"(RC) button then follow by T (RC)
button to go to the next step.

- If the test is not OK, press "RESUME"(RC) button then follow by
T (RC) button to go to the next step.

Note : By pressing only the T (RC) button to go to the next step without

triggering a confirmation, the test will be assume as OK by default.

Equipment required to run the DVD Player Test:

- television set

- 6 audio speakers

- an external video source
