TOSHIBA 42C3500PR
General recommendations for repairing TV LCD
It is advisable to start repairing the TOSHIBA 42C3500PR TV with an external examination of all its constituent elements, both internal electronic components and external. Inspection is also subject to body elements, control buttons, screen, connectors and cords. Any external damage can sometimes prompt the repairman to take further steps to determine the malfunction of the TV and localize the defect. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
If the TOSHIBA 42C3500PR does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a power module malfunction. It is advisable to start the troubleshooting of the power supply module by checking the mains fuse. If it is torn, it is necessary to check first of all the power semiconductor elements - rectifier diodes and the power switch of the converter, which are often found in a breakdown state in such situations.
As a rule, the keys of flyback converters, which use an N-Fet field effect transistor on a separate radiator, or integrated with a PWM controller in a single chip, are reliable enough and rarely fail for no reason. The reasons for the breakdown of the key should be sought by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
In cases where the Power Factor Corrector (PFC) is used in the power supply, troubleshooting can be a bit more complicated.
If the TOSHIBA 42C3500PR 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.
Repairing the inverter is difficult because in case of any malfunction or emergency, even with uneven wear of the lamps, a protection is triggered, which turns it off for fire safety. Diagnostics become impossible and protection needs to be disabled.
All necessary precautions must be observed when disabling the inverter protection during diagnostics and not leaving it disconnected after the repair is completed.
Remember! Attempts by users to repair the TOSHIBA 42C3500PR TV independently, without the appropriate qualifications and necessary experience, can lead to serious negative consequences!
