General repair guidelines for TV LCD LED
Repair of the FUSION FLTV-32K62 TV should begin with a careful external examination of all its components and modules. According to some external signs of a change in the state of some elements, it is sometimes possible to make assumptions about the nature of the defect, as well as determine the further direction of the troubleshooting. Experienced repairmen are well aware of what ring cracks in solder pins look like, swollen capacitors, and other causes of problems in electronic devices.
Sometimes the FUSION FLTV-32K62 TV simply does not turn on. No control lights on the front panel are lit or blinking, the TV does not respond to the remote control and does not make any sounds or any signs of life when turned on. The most likely cause of the malfunction is a failure of the common power module. If it is working properly, you must check the standby batteries on the Main Board. When diagnosing and repairing the power supply, first of all, replace the swollen capacitors of the filter of the secondary rectifiers and 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 and transistors in the primary circuit.
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 FUSION FLTV-32K62 does not have an image, but there is sound, the backlight LEDs of the LC320DXJ (SF) (E1) panel or their power converter may malfunction.
In case of breaks in the LED circuit, a complete disassembly of the panel is required, the LEDs are checked for an open circuit, 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 TP.VST59.P8B motherboard usually begins with a test of the performance of the stabilizers and power converters of the module chips. In some cases, a software update is required.
If it is not possible to replace the MB (SSB) card, you must check the health of its elements - CPU: TSUMV59XE-Z1; SPI Flash: 25Q32; . Defective components should be replaced.
It should be remembered! Attempts to repair the FUSION FLTV-32K62 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!
One of the typical FUSION FLTV-32K62 malfunctions often occurs in the LG panel LC320DXJ (SF) (E1).
External manifestations: there is no image, the backlight does not work. In most such cases, the LEDs turn out to be malfunctioning, which during testing turn out to be either in a cliff or with broken internal zener diodes.
LEDs must be replaced, and the maximum current from the driver should be limited to 10-20%.

TP.VST59.P8B can be used in TVs:
FUSION FLTV-32K62 (Panel LC320DXJ (SF)(E1)), FUSION FLTV-28K62 (Panel ST2751A01-4), THOMSON T32ED07U-01B (Panel LC320DXE (SF)(R1) ).
Main features of the FUSION FLTV-32K62 device:
Installed matrix (LED-panel) LC320DXJ (SF) (E1).
The matrix control uses the Timing Controller (T-CON) 6870C-0442B.
An integrated LED driver is used to power the backlight LEDs, it is controlled by the LD5850GS PWM controller. As the power elements of the LED driver, keys of the type ME15N10 are used.
The power module is combined with the MainBoard and is designed according to a flyback AC / DC voltage converter using PWM SOT23-6 microcircuits and power switches of the 7N65L type.
MainBoard - the main board (motherboard) is a TP.VST59.P8B module, using CPU chips: TSUMV59XE-Z1, SPI Flash: 25Q32, TPA3110LD2 and others.

Attention! The LC320DXJ (SF) (E1) panel of the FUSION FLTV-32K62 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.
