General repair guidelines for TV LCD LED
The FUSION FLTV-32C10 TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. In some cases, visible external damage to the elements can suggest the direction of troubleshooting and localization of the defect even before the start of the necessary measurements at the control points of the nodes of electronic circuits. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
In the case when the FLTV-32C10 does not turn on, does not respond to the remote control and buttons on the front panel, does not blink lights and does not show any signs of operability, the power supply module is probably defective in this case. If it is serviceable with such manifestations, it is necessary to check the stabilizer (converter) of the processor power supply on the motherboard. First of all, it is necessary to replace the swollen capacitors of the rectifier filters, if any. If the mains fuse is broken 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.
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 there is no image when you turn on the FUSION FLTV-32C10, or it appears for a second and disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the LVW320CSOT E81 V7 panel, or in their power converter. It is necessary to check the electrolytic capacitors of the filter of the secondary rectifiers in the general power supply unit.
Often there is a need for disassembling the panel to check the health of the LEDs, as well as contact connections in the connectors and soldering.
An open in the LED lines connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
Diagnostics and repair of the TP.MS18VG.P77 MS82PT motherboard 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.
Board repair and replacement of 25Q32 microcircuits are carried out in the presence of the necessary equipment, and the corresponding element base. Faults associated with the use of BGA processor soldering technologies can be localized by the heating method.
Attention! For users and owners of FLTV-32C10 TVs who do not have the appropriate qualifications, knowledge and experience, we strongly recommend against attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

In case of failures in the software of Winbond SPI FLASH microcircuits, they can for some time restore their performance after temperature exposure - heating the soldering station with a hairdryer or even a lighter. Usually this is enough to read the regular contents of the software. In such cases, the chip must be replaced with a new one.

Attention! The LVW320CSOT E81 V7 panel of the FUSION FLTV-32C10 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.
