In Brief: On this site you will find pictures and technical information about Service Modes, Circuit Diagrams, Firmware Update procedure, Disassemble procedure, Universal remote control set-up codes, Troubleshooting and more....

If you go into the profession, you will obtain or have access to a variety of tech tips databases HERE IT IS Master Electronics Repair !.

These are an excellent investment where the saying: 'time-is-money' rules. However, to learn, you need to develop a general troubleshooting approach - a logical, methodical, method of narrowing down the problem. A tech tip database might suggest: 'Replace C536' for a particular symptom. This is good advice for a specific problem on one model. However, what you really want to understand is why C536 was the cause and how to pinpoint the culprit in general even if you don't have a service manual or schematic and your tech tip database doesn't have an entry for your sick TV or VCR.

While schematics are nice, you won't always have them or be able to justify the purchase for a one-of repair. Therefore, in many cases, some reverse engineering will be necessary. The time will be well spent since even if you don't see another instance of the same model in your entire lifetime, you will have learned something in the process that can be applied to other equipment problems.
As always, when you get stuck, checking out a tech-tips database may quickly identify your problem and solution.In that case, you can greatly simplify your troubleshooting or at least confirm a diagnosis before ordering parts.

Happy repairing!

General repair guidelines for TV LCD LED
Possible manifestations of defects
- SAMSUNG UE32J6300 TV does not turn on at all. The control lights do not light or flash. The TV on the remote control and the control panel buttons do not respond.
Most likely in this case, the main switching power supply (IIP) BN44-00701B is faulty. It is necessary to measure the output voltages in its secondary circuits, and if they are completely absent, check the serviceability of the power switches (TK10A60W) and rectifier diodes for possible breakdown (short circuit).
In case of breakdowns of semiconductors in secondary circuits, the converter can usually work abnormally in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse often breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM) SPC7011F (FA5695), 3S111, in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
Failure in most such cases is detected in the nodes and backlight elements of the LED panel. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
It is impossible to detect a break in the LED line without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Typically, Chinese multimeters light up a single 3-volt LED, if you connect the probes in the forward direction to it (red probe to the anode, black to the cathode). In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as a health indicator. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights up constantly or blinks.
Repair or diagnostics of the BN41-02353B motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, you should update or replace the software (software). Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Verification or replacement of elements SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA requires the necessary training and professional skills in repairing modules at the component level. Problems associated with the use of BGA soldering technologies can sometimes be diagnosed by warming up.
If you suspect a malfunction of the tuner BN40-00318A (DNTS243H5A), first of all, you need to verify the correctness of the software, as well as the presence of the necessary voltage levels and pulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.
Attention TV owners! Attempts to self-repair SAMSUNG UE32J6300 are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the SAMSUNG UE32J6300 device:
Installed matrix (LED panel) CY-GH032CSLV5V.
The matrix control uses the Timing Controller (T-CON) BN95-01307B.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a 7014X PWM controller. As power elements of the LED driver, keys of the AOD9N40 type are used.
The necessary supply voltages for all nodes of the SAMSUNG UE32J6300 TV are generated by the BN44-00701B power module or its analogs using SPC7011F (FA5695), 3S111 microcircuits and TK10A60W power switches.
MainBoard - the main board (motherboard) is a BN41-02353B module, using microchips SDP1415, EMMC: THGBMBG5D1KBAIT, RAM: K4B4G16460-BCMA and others.
The tuner BN40-00318A (DNTS243H5A) provides the reception of television programs and tuning to channels.
