General repair guidelines for TV LCD LED
Possible malfunctions
- SAMSUNG UE55H6500 does not turn on and does not show any signs of performance at all. Does not blink indicators and does not respond to control buttons.
Failure in such cases should begin to be sought in the power supply circuits of BN44-00711A. It is necessary to measure its output voltages and, in case of their absence, check the serviceability of power switches and rectifier diodes in the converters for possible breakdown.
In case of breakdowns of semiconductors in the secondary circuits of any converter, as a rule, it can operate in emergency short-circuit mode without output voltages, and during short circuit in the elements of the primary circuit, the main fuse and, less often, the current sensor at the source of the key are most often cut off.
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) S3051 (PFC), FA6A01N, in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, there is sound, it is responding to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
In some of these cases, the malfunction is caused by a lack of backlighting on the display. The reason can be both in the power of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
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 an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the BN41-02156A motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, 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. Checking or replacing elements BN40-00288A CPU: SEMS-31, SPI-FLASH: 25Q40, EEPROM: 24C512 requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can sometimes be diagnosed by warming up.
If the TV works normally from external devices, but does not tune into television channels, the tuner BN40-00288A may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding conclusions. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus. Sometimes the cause of the inoperability of the tuner may be a software failure.
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Entrust repair to professionals with sufficient experience in the field of repair of electronic equipment.

Main features of the SAMSUNG UE55H6500 device:
Installed matrix (LED panel) CY-GH055CSLV7V.
The matrix control uses the Timing Controller (T-CON) BN95-01310A.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a 7014X PWM controller.
The necessary supply voltages for all nodes of the SAMSUNG UE55H6500 TV are generated by the BN44-00711A power module, or its analogs using S3051 (PFC), FA6A01N microcircuits.
MainBoard - the main board (motherboard) is a BN41-02156A module, using BN40-00288A CPU chips: SEMS-31, SPI-FLASH: 25Q40, EEPROM: 24C512 and others.
The tuner BN40-00288A provides the reception of television programs and tuning to channels.
