Repair of Electronic Equipment usually Begins with ITS External Inspection and Diagnosis of The Malfunction. The In the this Case, you Should Inspect All Internal Components of The the TV the SAMSUNG UE32C4000PW, AS Well AS External Parts of The Case. Often field, based ON External Signs and The Nature Of damage to elements, it becomes possible to draw some conclusions and determine a further algorithms for finding a defect before making the necessary measurements at control points. Electrolytic capacitors of filters with a swollen casing, as well as annular cracks or a layer of In the soldering points of heating elements, sometimes prompt the repairman of the cause of the malfunction and possible effects. In cases when the TV SAMSUNG UE32C4000PW does not turn on, does not respond to the remote and the buttons, no indicators on the front panel flash and blink and there are no sounds at all and no signs of operability at all - the PD32AF0F_ZDY Code: BN44- 00349B or there is no processor power on the motherboard (typical defect of some models of SAMSUNG TVs). When diagnosing and repairing the power supply, after replacing the blown capacitors of the secondary rectifier filters (if any), you first need to Check the mains fuse. When it breaks, you should check the power elements of the transistors and rectifier bridge diodes for an avalanche (thermal) breakdown.
Power Switches in Switching Power Supplies is the source (SMPS) Fail the without Reasons Very constructions rarely and, in Case of Breakdown, IT IS Necessary to Search for A Malfunction in at The Stabilization Circuits by Checking at The Electrolytic Capacitors, Semiconductor Devices and Resistors in at The Primary Circuit. At The the cause is May be a malfunction of the STR-W6052S PWM controller chip FSQ0565R SELC2010M, which can only be checked for replacement with a new or known good.
If there is no image when the SAMSUNG UE32C4000PW is turned on, or it appears for a second and disappears, but there is a sound, it is most likely a malfunction in the LED backlight circuit of the T320HAE1-DB 32P6AH0E panel, or in their Power supply . It is necessary to check the electrolytic capacitors of the secondary rectifier filter in the common power supply.
In most cases of lack of backlighting, there is a need to disassemble the panel in order to check the LEDs, connectors, loops and all Contact connections. If one or several LEDs do not work in one ruler, they are preferably broken and should be replaced.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panel using a tester or multimeter without an additional device, for example, a current source. To open all PN transitions connected in series at once, a Voltage of several tens of volts may be required. If the motherboard SX1_LED_LARGE Code: BN41-01378A is faulty, first of all it is necessary to check all linear stabilizers or power converters of its chips, and also, if necessary, to update the software of the software. Sometimes it is possible to check at The Serviceability of at The MB only by Replacing IT.
the When Repairing at The MB Card, IS Necessary to the Check the ITS Components MX25L4005A STA369BWS AT24C256C. IT Defective items Should BE REPLACED. the If BGA Chips are Installed, Their Malfunction IS usually Localized by Warm-up. the If Chips with BGA soldering technology are used, the problem in its implementation is detected by the method of local chip heating.
In cases where there is no setting for local television channels, you should make sure that there is a supply voltage of the varicaps (30-33V) and other supply voltages on the DTOS40CVH081A tuner terminals BN40-00172A
