General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular SAMSUNG UE32F6200, it is advisable to start with a careful external examination of internal and external elements. Visible damage to the elements can sometimes indicate the direction of the search for the defect even before the start of the necessary measurements. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of the already known typical malfunction.
In the absence of any signs of operability, when the SAMSUNG UE32F6200 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 TV power supply SBN44-00615A module. With the same manifestations, the power regulator of the control processor on the motherboard may be faulty. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip may also cause a breakdown of the power switch of the converter.
If the SAMSUNG UE32F6200 does not have an image, but there is sound and the TV is controlled by the remote control, a malfunction in the backlight circuits of the CY HF320BGLV2V panel is likely. The LEDs or the power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the LED driver, and check the LEDs, connecting obviously known good diagnostics.
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.
It is impossible to check the LED line for breaks without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally, a current source.
In cases of attempts to repair the BN41-01958A motherboard, it is necessary to check the operability of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
When repairing an MB card, you must check its SDRAM components: 4B2G1646E. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating.
If you suspect that the tuner BN40-00262A is malfunctioning, first of all, you need to make sure that the voltage of the varicaps (30-33V) is on the corresponding output of the tuner, as well as other voltage supplying it.
Owners and users of the SAMSUNG UE32F6200 TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!
One of the typical SAMSUNG UE32F6200 malfunctions often occurs in Samsung LED panels CY HF320BGLV2V.
External manifestations: no image, the backlight does not work. The LED driver provides maximum voltage for powering the LEDs. Usually the LEDs themselves turn out to be faulty, which, when tested, turn out to be either in a cliff or with broken internal zener diodes.
The LEDs in this case must be replaced, and the maximum driver current limited by 10-20% according to the bulletin from the manufacturer.

Main features of the SAMSUNG UE32F6200 device:
Installed matrix (LED-panel) CY-HF320BGLV2V.
The matrix control uses the Timing Controller (T-CON) BN41-01938B.
To power the backlight LEDs, a converter is used, combined with the power supply, controlled by the PLC controller SLC1012C (FAN7340).
The necessary supply voltages for all nodes of the SAMSUNG UE32F6200 TV are generated by the BN44-00615A power module, or its analogs using 2S110, SPS1013P (Standby) microcircuits.
MainBoard - the main board (motherboard) is a BN41-01958A module, using SDRAM chips: 4B2G1646E and others.
The tuner BN40-00262A provides the reception of television programs and tuning to channels.
