TOSHIBA 15SLDT2
General recommendations for repairing TV LCD
TOSHIBA 15SLDT2 TV, like any other, it is advisable to start repairing it by examining the internal and external visible physical visual changes. Often, by the external signs and nature of some damage, it is possible to draw preliminary conclusions and determine a further algorithm for troubleshooting. In most cases, the repairman can guess the causes of the defect and possible consequences by the characteristic signs of typical TV defects, for example, ring cracks formed in the soldering of element leads, swollen rectifier filter capacitors, charred resistors and other circuit elements.
If the CEG373A power supply module (3) fails, the external manifestations may be different, for example, the TOSHIBA 15SLDT2 does not turn on at all and there is no indication of the indicator lights on the front panel. When diagnosing and repairing the power supply, first of all, it is necessary to 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 or power switch 2SK3532.
Power switches in flyback converters fail extremely rarely for no reason and, if they are broken, it is necessary to look for a malfunction in the stabilization circuits by checking electrolytic capacitors, semiconductor devices, and resistors in the primary circuit. The reason may be a malfunction of the PWM controller chip 2A08603 5531 (8), which can only be checked by replacing it with a new or obviously working one.
When using a power factor correction unit (PFC) in the power modules, troubleshooting becomes somewhat more complicated and requires additional experience and knowledge of their operation.
If the TOSHIBA 15SLDT2 does not have an image, but there is sound, there is a possibility of a malfunction of the backlight or power converter. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
Diagnosis and repair of the inverter is often complicated by the organization of special protection circuits, which is necessary for fire safety and turns off the inverter in any emergency situation, for example, when the lamps are worn or depressurized. Often, to localize a defect, its blocking is required.
When diagnosing with the protection off, special precautions must be taken, because there is a risk of failure of the power elements of the inverter. After the diagnosis, it is imperative to restore the protection circuits for the inverter to operate normally.
The CMG130A motherboard must be checked if there is no reaction to the remote control and function buttons, the standby indicator blinks or stays on. In such cases, if the power supply circuits of the microcircuits are working, a software update may be necessary. In some cases, to repair the MB (SSB) board, it may be necessary to replace the chips - VCT 6973G B3 000, 24c256bn with new or obviously working ones.
Owners and users of the TOSHIBA 15SLDT2 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!

Main features of the TOSHIBA 15SLDT2 device:
Installed matrix (LCD panel) CLAA150XP07FQ (V7201) AE009749 09EK115007.
The matrix control uses the Timing Controller (T-CON) CPT.
To power the backlight, a CEG373A inverter (3) is used, it is controlled by the BD9882 LM2902, LA42052 PWM controller. The transformer T905 Y8D2 is installed in the inverter converter.
The necessary supply voltages for all nodes of the TOSHIBA 15SLDT2 TV are generated by the ETL-XPC-204T power module or its analogs using FA5531 microcircuits (8pin) and power switches of the 2SK3532 type.
MainBoard - the main board (motherboard) is a CMG130A module, using VCT 6973G B3 000 chips, SUB MICON: R5F21244SN, EEPROM AT24C256BN, ZR36966ELCG-D-G, SST39VF1601-70-4C-EKE and others.
The TDTG-S486D tuner provides TV reception and channel tuning.
