Witam, padł mi telewizor (już drugi w tym miesiącu - chyba się załamię :( ) mianowicie po włączeniu telewizor wyłącza się i zaczyna migać czerwona dioda 5 x. Gdy telewizor stał tydzień odłączony, po ponownym włączeniu pojawił się napis HDMI, telewizor działał może z 5 sekund po czym wyłączył się i zaczął mrugać 4x, teraz po włączeniu tylko 5x mruga. Z opisów wyczytałem, że to moduł T-con? Napięcia z zasilacza w trybie standby 12,45V po właczeniu i gdy zaczyna mrugać 0, w trybie standby na listwy ledowe idzie 6,4V (na każdej linii w każdym z 4 złączy). Sprawdziłem PANEL_VCC 12.5V - niestety 0 V oraz JL9112 (BACKLIGHT_MON) - ma być między 0.98V a 1.23V, w standby 0,4V później 0V. Proszę o jakieś rady. edit: mrugająca 5x dioda wskazuje na T-CON, ale czy może być tak że jest ok tak jak led driver (obraz - podświetlony pojawia się na 1s) a paski diodowe nie działają prawidłowo i gdy system logiczny mierzy np pobór napięcia na pasku a dioda jest przerwana to wyłącza telewizor i wykazuje błąd?

CAUTIONS AND WARNINGS
CAUTION!!
ATTENTION!!
These servicing instructions are for use by qualified service personnel only.
To reduce the risk of electric shock, do not perform any servicing other than
that contained in the operating instructions unless you are qualified to do so.
Ces instructions de service sont à l’usage du personnel de service qualifié
seulement. Pour prévenir le risque de choc électrique, ne pas faire l’entretien
autre que celui contenu dans le Mode d’emploi à moins que vous soyez
qualifié faire ainsi.
WARNING!!
An isolation transformer should be used during any service to avoid possible
shock hazard, in case of live chassis.
!
SAFETY-RELATED COMPONENT WARNING!!
There are critical components used in LCD color TVs that are important for
safety. These components are identified with shading and ! mark on the
schematic diagrams and the parts list. It is essential that these critical parts
be replaced only with the part number specified in the parts list to prevent
electric shock, fire or other hazard.
ALERTE!!
Afin d’eviter tout risque d’electrocution provenant d’un chássis sous tension,
un transformateur d’isolement doit etre utilisé lors de tout dépannage.
!
ATTENTION AUX COMPOSANTS
RELATIFS A LA SECURITE!!
ATTENTION!!
Les composants identifies par une trame et par une marque ! sur les
schemas de principe, les vues explosees et les listes de pieces sont d’une
importance critique pour la securite du fonctionnement. Ne les remplacer
que par des composants Sony dont le numero de piece est indique dans le
present manuel ou dans des supplements publies par Sony. Les reglages
de circuit dont l’importance est critique pour la securite du fonctionnement
sont identifies dans le present manuel. Suivre ces procedures lors de
chaque remplacement de composants critiques, ou lorsqu’un mauvais
fonctionnement suspecte.
For safety reasons, component level repair of the Power Supply Boards
and/or the Inverter Boards is prohibited.
ATTENTION!!
NOTE: Do not modify the original design without obtaining written permission
from the manufacturer or you will void the original parts and labor warranty.
CAUTION ABOUT THE LITHIUM BATTERY!!
Replace only with the same or equivalent type. Danger of explosion may
occur if battery is replaced incorrectly. Exposed battery should not be in
contact with water.
Pour des raisons de sécurité, Interdire de réparer ou remplacer les
composantes dans les blocs d’alimentation et/ou sur les modules d’inverseur.
AVERTISSEMENT AU SUJET
DE LA PILE AU LITHIUM!!
Ne remplacez qu’avec une pile de type identique ou équivalent. Danger
d’explosion si la pile est remplacée incorrectement. La pile exposée ne
devrait pas être mise en contact avec de l’eau.
KDL-55W900A ii
CAUTIONS AND WARNINGS
SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety
checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly soldered
connections. Check the entire board surface for solder splashes
and bridges.
3. Measuring the voltage drop across a resistor by means of a VOM
or battery-operated AC voltmeter. The “limit” indication is 0.75 V, so
analog meters must have an accurate low voltage scale. Nearly all
battery-operated digital multimeters that have a 2 VAC range are
suitable. (see Figure A)
To Exposed Metal
Parts on Set
2. Check the interboard wiring to ensure that no wires are “pinched” or
touching high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps and
mounting hardware have been replaced. Be absolutely certain that
you have replaced all the insulators.
AC
Voltmeter
(0.75V)
0.15 µF
4. Look for unauthorized replacement parts, particularly transistors,
that were installed during a previous repair. Point them out to the
customer and recommend their replacement.
5. Look for parts which, though functioning, show obvious signs of
deterioration. Point them out to the customer and recommend their
replacement.
6. Check the line cords for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
7. Check the antenna terminals, metal trim, “metallized” knobs, screws
and all other exposed metal parts for AC leakage. Check leakage
as described in “Leakage Test”.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all
exposed metal parts to any exposed metal part having a return to chassis,
must not exceed 0.5 mA (500 microamperes). Leakage current can be
measured by any one of three methods.
Earth Ground
Figure A. Use an AC voltmeter to check AC leakage.
HOW TO FIND A GOOD EARTH GROUND
The cover-plate retaining screw on most AC outlet boxes is at earth ground.
Verify the AC outlet box retaining screw ground by connecting a 60W to
100W incandescent (not a neon or fluorescent lamp) between the hot side of
the receptacle and the retaining screw. Try both slots, if necessary, to locate
the hot side on the line; the lamp should light at normal brilliance if the screw
is at ground potential. (see Figure B)
Trouble Light

1. A commercial leakage tester.
Follow the manufacturers’ instructions provided with the tester.
2. A battery-operated AC milliammeter.

Before servicing the Television:
1. Verify the TV has the symptom the customer indicated.
SELF CHECK
2. Check to see if the latest Software is installed.
a. If not, install the latest version.
3. Determine the replacement part required.
VIEWING THE SELF CHECK DIAGNOSIS HISTORY
When an error is detected, the Self Check screen records the number of
times the error occurred. This is helpful in confirming past occurrences of
an error and for determining if an error is intermittent when the customer is
not sure what is causing the television to shut down. If the screen displays
a “0”, no error has occurred.
1. Press
