TOSHIBA 32TL963RB
General repair guidelines for TV LCD LED
Repair of all electronic devices, including the TOSHIBA 32TL963RB TV, it is advisable to start with an external examination of its external and internal elements. It often happens that visible damage to elements or connections helps determine the direction of the troubleshooting. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
Faults in the DPS-115EP A, 75026932 power supply module can be expressed in different ways, for example, the TOSHIBA 32TL963RB does not turn on at all and the control lamps on its front panel do not light up and do not blink, and there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is cut off in the power supply, in most cases a breakdown of the power key (s) is detected, which can be integrated with the PWM controller, or a separate field-effect transistor can be used. The rectifier bridge diodes and the electrolytic capacitor of the mains rectifier filter should also be checked.
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 A6069H (7), 1608B (8), DDA014 (18) can also cause a breakdown of the power switch of the converter.
In cases where the TOSHIBA 32TL963RB TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of a malfunction of the LED driver (converter for powering the backlight LEDs of the V315H3-LS5 Rev C1 panel. 75028476). When you turn on the TV, the image may appear briefly and disappear immediately. It must be borne in mind that with such manifestations the LEDs themselves also fail.
A malfunction in the backlight circuits often occurs due to an open in the power circuit of the LED lines. It requires disassembling the panel and checking the LEDs themselves, the rations of their terminals, as well as the reliability of the connections in the connectors and rations of the terminals.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
Diagnostics and repair of the motherboard PE1063E V28A001396A1 75031969 is carried out by checking the performance of the stabilizers or power converters of the module chips. In some cases, a software update is required.
When repairing an MB board, you must check its components AO Z1094DI (8), TCV 7103AF (8), 00COW 2171 BD00IC0WEFJ-E2 (8), AOZ1361DI-02 (10), LNBH23QTR. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating. If chips with BGA soldering technology are used, a problem in its implementation is detected by the local heating of the chip.
If the TV works normally from external devices, but does not tune to television channels, the ENGS7305D5F tuner may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals, as well as the power supply of varicaps (30-33V).
Attention! Users and owners of 32TL963RB televisions who do not have the appropriate qualifications, knowledge and experience are strongly advised against self-repair attempts to avoid negative consequences that could lead to complete non-serviceability of the device.

PSU Advanced
On the 32TL963RB TV, the DPS-115EP power module is installed using the PFC (Power Factor Correction) scheme acting as an active filter to eliminate the higher harmonic components of the current consumption. The boost converter based on the 1608B PWM controller does not allow the input rectifier filter's electrolytic capacitor to be connected to the network directly through open diodes when the reactance (about 15-30 ohms at a frequency of 50 Hz) determines the charge current. As a result of the conversion, the charging current of the capacitor will be determined in such a way that the envelope of the high-frequency pulses of the input current will repeat the phase and shape of the sine wave of the input voltage. The health check of the PFC unit is carried out by measuring the DC voltage on the capacitor of the rectifier network. In operating mode, it should be around 380V, in standby approximately 300V.

Attention! The V315H3-LS5 Rev C1 panel of the TOSHIBA 32TL963 LED TV is an expensive and unreliable element.
Avoid any impact on the glass and pressure on the surface of the screen to avoid damage to the LED panel!
It is also unsafe to get liquid on the screen. Sometimes one drop is enough if it flows down the glass onto the cables so that the TV becomes unrepairable.
