Dobry wieczór, próbuje naprawić telewizor LCD Toshiba 37XV505D z panelem LC370WUN SAB1 ( inwerter 6632L-0490A ). Objawy jakie mam to brak obrazu (podświetlenia) , jest dźwięk, podświetlając latarką ekran widzę np. menu telewizora. Niebieska dioda na inwerterze nie świeci w ogóle. Poniżej napięcia pomierzone na płycie zasilającej: P811A: 14131211109876543210V17,89V3,8V23,85V0V4,89V4,89V0V11,89V11,89V11,89V0V5V0V P810A: 9876543211,6V3,8V3,6V0V3,26V0V0V12V12V P860: 10...65...10V0V0V24V24V24V Inwerter: 1413121110...65...11,6V0V5V0,05V0V0V0V23,98V23,98V23,98V Napięcia z płyty zasilającej wydają mi się być poprawne, dlatego zacząłem badać płytę inwertera i tam wydaje mi się, że sygnał status jest niepoprawny bo wg dokumentacji do panelu poprawne napięcie to więcej niż 3V. Na płycie inwertera miałem spuchnięte dwa kondensatory 680uF 35V, które wymieniłem, niestety to nie pomogło. Po lekturze forum wylutowałem cztery widoczne MOSFETY i je sprawdziłem miernikiem, wydają się być dobre. Sprawdziłem też rezystancje uzwojenia wtórnego obydwu transformatorów i wynosi ona około 40 Ω, rezystancja uzwojeń pierwotnych to ~0Ω, wydaje mi się, że w porządku. Następnie zacząłem sprawdzać układ BD9897FS, oprócz zwarcia do masy na nóżkach 1, 11 ( co jest normalne wg mnie ) mam jeszcze zwarcia na nóżkach 27 oraz 28. Tutaj nie wiem czy to normalne bo nie mam schematu oraz zbyt dużego doświadczenia w serwisowaniu LCD. BTW bezpiecznik na inwerterze cały. Załączam datasheety, które udało mi się znaleźć https://obrazki.elektroda.pl/9356166300_1572209570_thumb.jpg https://obrazki.elektroda.pl/2349588400_1572211710_thumb.jpg

Product Specification
1. General Description
The LC370WUN is a Color Active Matrix Liquid Crystal Display with an integral External Electrode
Fluorescent Lamp(EEFL) backlight system. The matrix employs a-Si Thin Film Transistor as the active
element. It is a transmissive display type which is operating in the normally black mode. It has a 37 inch
diagonally measured active display area with WUXGA resolution (1080 vertical by 1920 horizontal pixel
array). Each pixel is divided into Red, Green and Blue sub-pixels or dots which are arrayed in vertical stripes.
Gray scale or the luminance of the sub-pixel color is determined with a 10-bit gray scale signal for each dot.
Therefore, it can present a palette of more than 1.06B (true) colors.
It has been designed to apply the 10-bit 2-port LVDS interface.
It is intended to support LCD TV, PCTV where high brightness, super wide viewing angle, high color gamut,
high color depth and fast response time are important.

Note :
1. The pin no 44 is LCD Test option. “AGP” (Auto Generation LCM operates Pattern) or “NSB” (No Signal
Black) is case that LVDS signals are out of frequency or abnormal condition in spite of 12 volt power
supply. LPL recommends “NSB”. ( AGP : “VCC” or “OPEN” / NSB : “GND” )
2. All GND(ground) pins should be connected together to the LCD module’s metal frame.
3. All VLCD (power input) pins should be connected together.
4. All Input levels of LVDS signals are based on the IEA 664 Standard.
5. Specific pins(pin No. #1~#10) are used for internal data process of the LCD module.
If not used, these pins are no connection.
6. If DCR function should be enable(‘H’), 10th pin must be connected to serial resistor which value is under
1k ohm.

9. Precautions
Please pay attention to the followings when you use this TFT LCD module.
9-1. Mounting Precautions
(1) You must mount a module using specified mounting holes (Details refer to the drawings).
(2) You should consider the mounting structure so that uneven force (ex. Twisted stress) is not applied to the
module. And the case on which a module is mounted should have sufficient strength so that external
force is not transmitted directly to the module.
(3) Please attach the surface transparent protective plate to the surface in order to protect the polarizer.
Transparent protective plate should have sufficient strength in order to the resist external force.
(4) You should adopt radiation structure to satisfy the temperature specification.
(5) Acetic acid type and chlorine type materials for the cover case are not desirable because the former
generates corrosive gas of attacking the polarizer at high temperature and the latter causes circuit break
by electro-chemical reaction.
(6) Do not touch, push or rub the exposed polarizers with glass, tweezers or anything harder than HB
pencil lead. And please do not rub with dust clothes with chemical treatment.
Do not touch the surface of polarizer for bare hand or greasy cloth.(Some cosmetics are detrimental
to the polarizer.)
(7) When the surface becomes dusty, please wipe gently with absorbent cotton or other soft materials like
chamois soaks with petroleum benzine. Normal-hexane is recommended for cleaning the adhesives
used to attach front / rear polarizers. Do not use acetone, toluene and alcohol because they cause
chemical damage to the polarizer.
(8) Wipe off saliva or water drops as soon as possible. Their long time contact with polarizer causes
deformations and color fading.
(9) Do not open the case because inside circuits do not have sufficient strength.
9-2. Operating Precautions
(1) The spike noise causes the mis-operation of circuits. It should be lower than following voltage :
V=± 200mV(Over and under shoot voltage)
(2) Response time depends on the temperature.(In lower temperature, it becomes longer.)
(3) Brightness depends on the temperature. (In lower temperature, it becomes lower.)
And in lower temperature, response time(required time that brightness is stable after turned on)
becomes longer
(4) Be careful for condensation at sudden temperature change.Condensation makes damage to polarizer or
electrical contacted parts. And after fading condensation, smear or spot will occur.
(5) When fixed patterns are displayed for a long time, remnant image is likely to occur.
(6) Module has high frequency circuits. Sufficient suppression to the electromagnetic interference shall be
done by system manufacturers. Grounding and shielding methods may be important to minimized the
interference.
(7) Please do not give any mechanical and/or acoustical impact to LCM. Otherwise, LCM can’t be operated
its full characteristics perfectly.
(8) A screw which is fastened up the steels should be a machine screw.
(if not, it can causes conductive particles and deal LCM a fatal blow)
(9) Please do not set LCD on its edge.
(10) It is recommended to avoid the signal cable and conductive material over the inverter transformer
for it can cause the abnormal display and temperature rising.

9-3. Electrostatic Discharge Control
Since a module is composed of electronic circuits, it is not strong to electrostatic discharge. Make certain that
treatment persons are connected to ground through wrist band etc. And don’t touch interface pin directly.
9-4. Precautions for Strong Light Exposure
Strong light exposure causes degradation of polarizer and color filter.
9-5. Storage
When storing modules as spares for a long time, the following precautions are necessary.
(1) Store them in a dark place. Do not expose the module to sunlight or fluorescent light. Keep the temperature
between 5° and 35° at normal humidity.
C
C
(2) The polarizer surface should not come in contact with any other object.
It is recommended that they be stored in the container in which they were shipped.
9-6. Handling Precautions for Protection Film
(1) The protection film is attached to the bezel with a small masking tape.
When the protection film is peeled off, static electricity is generated between the film and polarizer.
This should be peeled off slowly and carefully by people who are electrically grounded and with well ionblown equipment or in such a condition, etc.
(2) When the module with protection film attached is stored for a long time, sometimes there remains a very
small amount of glue still on the bezel after the protection film is peeled off.
(3) You can remove the glue easily. When the glue remains on the bezel surface or its vestige is recognized,
please wipe them off with absorbent cotton waste or other soft material like chamois soaked with normalhexane.

Function
Maximum Brightness (100%)
(DCR Condition)
Minimum Brightness (10%)
Note : 1. To make DCR Max (Bare CR)X10, VBR-A and VBR-B must be given by system.
2. DCR Max 10,000:1 is defined mathematically as :
DCR = Maximum DCRn (n=1, 2, 3, 4, 5)
Surface Luminance at position n with all white pixels (VBR-B=3.3V, VBR-A=1.65V)
DCRn =
Surface Luminance at position n with all black pixels (VBR-B=0V, VBR-A=0V)
n = the Position number(1, 2, 3, 4, 5). For more information, see FIG 2.
3. Measurement Sequence (aging time 10 min each pattern) :
Turn On LCM
Measure Black Luminance (VBR-B=0V, VBR-A=0V)
Measure White Luminance (VBR-B=3.3V, VBR-A=1.65V)
4. In case the lowest minimum brightness is continued,
it can affect the lamp reliability and appear the partial darkness.
