TOSHIBA 40TL933R
General repair guidelines for TV LCD LED
Diagnostics of malfunctions and repairs of the TOSHIBA 40TL933R, as well as other electronic devices, is recommended to begin with an external examination of the external and internal elements. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the solders of the terminals of transformers or heating elements are found, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
Malfunctions of the power module can be expressed in different ways, for example, the TOSHIBA 40TL933R does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) 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.
It should be remembered that in the practice of repair, usually the power switches in switching power supplies (SMPS) do not fail due to their poor quality and, in such cases, it is necessary to look for the cause that led to a malfunction and provoked a breakdown of the key. Most often, the culprits of the accident are dried electrolytic capacitors or dangling resistors in the primary circuit, or the PWM controller chip itself may be faulty. It is also necessary to check all the semiconductor elements of the stabilization circuit in the primary and secondary circuits.
If the TOSHIBA 40TL933R TV does not have an image, but there is sound, a malfunction in the LED backlight circuits is likely. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for an overstated ESR.
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 detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
In cases of attempts to repair the motherboard PE1063 C V28A001396A1C 75025187 90-EB40M00D0, 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.
If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - TAS5707L, 25Q64CVSIG, MSD3704PX-LF-SA, FA1EA, G61MB. Defective components should be replaced.
Before replacing the TDTK-G641D tuner, if there is no tuning to the channels, you must first check the power supply voltage at its terminals, including the power supply of varicaps (30-33V).
Attention to the owners! Attempts to self-repair the TOSHIBA 40TL933R TV are not recommended by the manufacturer and can lead to serious negative consequences!
