General repair guidelines for TV LCD LED
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should examine all the internal components of the SAMSUNG UE37C5100 QW TV, as well as the external elements of the case. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localize the defect before the necessary measurements are taken. Carbonized paint on the upper layer of resistors, electrolytic capacitors of rectifier filters swollen after boiling, cracked soldering at the terminals of heating elements or transformers can often suggest the cause of the defect and possible consequences.
In the absence of any signs of operability, when the SAMSUNG UE37C5100 does not turn on and does not signal anything with the control lights on the panel, there is a possibility of a malfunction of the power supply BN44-00351B PD37AF0E_ZDY of the TV. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. It is advisable to start the troubleshooting of the power supply module by checking the state of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in such a state of breakdown.
The reasons for the breakdown of the power switch in switching power supplies (IIPS) can be different, for example, a malfunction of semiconductor cells or electrolytic capacitors in the stabilization circuits of the primary circuit, as well as a failure in the operation of the PWM controller chip or breakage of the resistors in its bundle.
Sometimes the SAMSUNG UE37C5100 TV does not have an image, but there is sound, or the image appears and immediately disappears. In this case, there is a high probability of a malfunction of the T370FAE1-DA backlight LED converter, or an open circuit in the LED circuit is possible. In such cases, first of all, it is necessary to verify the serviceability of all the electrolytic capacitors of the filter by supplying the LED driver itself, including in the power supply unit (power supply unit).
In most cases of lack of backlight, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
An open in the LED lines connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
Repair or diagnostics of the BN41-01378A motherboard should begin by checking the stabilizers or power converters of its microcircuits. If necessary, update 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 ATMLH010 2EB, MX25L4005, ATMLH004 02B requires the necessary training and professional skills in repairing modules at the component level. Problems associated with the use of BGA soldering technologies can be diagnosed by warming up.
If there is no reception of television channels, but the TV works properly from external devices, first of all, check the voltage of the tuner BN40-00172A DTOS40CVH081A.
Once again, remind users! Attempts to self-repair a SAMSUNG UE37C5100 TV without the appropriate qualifications and experience can lead to its complete non-repairability!

Main features of the SAMSUNG UE37C5100 device:
Installed matrix (LED panel) T370FAE1-DA.
The matrix control uses the Timing Controller (T-CON) T370HW04.
To power the backlight LEDs, a converter is used, combined with a power supply.
The formation of the necessary supply voltages for all nodes of the SAMSUNG UE37C5100 TV is carried out by the BN44-00351B power module, or its analogs using STR-W6052S microcircuits.
MainBoard - the main board (motherboard) is a BN41-01378A module, using the MX25L4005A STA369BWS AT24C256C chips and others.
Tuner BN40-00172A DTOS40CVH081A provides the reception of television programs and tuning to channels.
