General repair guidelines for TV LCD LED
In the case when the UE37D6100 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink light bulbs and does not show any signs of operability, the power supply module BN44-00458B is probably faulty in this case. Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse breaks, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is checked by replacing it with a known good one.
If, when you turn on the TV, the image appears and immediately disappears, or is initially absent when you turn on, but the sound has other functions that work, there is a high probability of a malfunction of the LED driver (power converter for the backlight LEDs of the LD370CGB-C2 panel).
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the lines and connectors.
To check the health in the LED circuit it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can test each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the LED will light up slightly.
In cases of attempts to repair the BN41-01604C BN94-05370G motherboard, it is necessary to check the operability of the linear stabilizers and power converters of its microcircuits and, if possible, update the software (software). BGA chips can sometimes be diagnosed by local heating.
When repairing the MB board, it is necessary to check the performance of the stabilizers and power converters of microcircuits. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating.
Before replacing the DTOS403VH083A tuner, if there is no tuning for the channels, you must first check the software, the supply voltage at its terminals, and the data exchange with the processor.

It should be remembered! Attempts to repair the SAMSUNG UE37D6100 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

PSU Advanced
The UE37D6100 model uses the BN44-00458B power supply unit using the PFC (Power Factor Correction) node - an active filter of the highest harmonics of the current consumption. In fact, it is a boost converter based on the PWM controller SPC7011F = FA5695N, which eliminates the charge current of the electrolytic capacitor of the rectifier filter directly from the network through open diodes when its charging current is determined by its reactance.
As a result of the operation of the converter, the envelope of the high-frequency pulses of the input current of the converter will repeat the shape and phase of the input voltage. The health of the PFC node can be indirectly judged by the presence of an increased constant voltage (about + 380V) on the capacitor of the rectifier network in operating mode.

Main features of the SAMSUNG UE37D6100 device:
Installed matrix (LED-panel) LD370CGB-C2.
The matrix control uses the Timing Controller (T-CON) T370HW05.
To power the backlight LEDs, a converter is used, combined with a power supply unit, controlled by the SLC3011M PWM controller.The necessary supply voltages for all nodes of the SAMSUNG UE37D6100 TV are generated by the BN44-00458B power module or its analogs using the STR-A6052M, SPC7011F (PFC = FA5695N), FSFR1800XSL microchips and MDS1653RH type power switches.
MainBoard - the main board (motherboard) is a BN41-01604C module, using CPU chips: SDP1001; NAND Flash: KFG2G16Q2M; WT61P805, Sil9489ACTUC and others.
Tuner DTOS403VH083A provides the reception of television programs and tuning to channels.
For masters and advanced users
If the SAMSUNG UE37D6100 does not have an image, but there is sound, the backlight of the LD370CGB-C2 often simply does not work. Moreover, LED-TVs usually fail LEDs inside the panel, less often LED-driver.
In such cases, you can see a barely noticeable image when the ambient light successfully hits the screen.
To replace the LEDs, disassembling the LD370CGB-C2 LCD panel is required - a process that requires experience and qualification from the master. We do not recommend doing such work on your own for TV owners and craftsmen who do not have experience repairing LCD panels
If there is no image, but the backlight works, the screen becomes a little lighter when you turn it on, and in the open TV you can see the light through the holes in the panel case.
In this case, the panel may also be malfunctioning - damage to the strips, loops, for example, as a result of moisture ingress after an unsuccessful washing of the screen, the T-CON (Timing Controller) board may be malfunctioning. But often the MainBoard BN41-01604C mainboard also turns out to be faulty, and a software failure is also possible.
Then, first of all, it is necessary to check the panel supply voltage, fuses on the T-CON board, as well as the supply and reference voltages of column and line drivers - VGH, VGL, Vcom.
If these measurements are within the normal range, it is necessary to use an oscilloscope to track the passage of LVDS signals from the MainBoard BN41-01604C, as well as synchronizing signals to the loops with the drivers.
Flooded or poorly washed LED-TV screens have the opportunity to recover, in about half the cases, usually if significant damage has not formed in the cables and planks of the panel.
