General repair guidelines for TV LCD LED
The FUSION FLTV-32T22 TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Many visible changes in the state of the elements make it possible to determine the future direction of troubleshooting and localization of the defect. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in soldering will help the master to guess the causes and possible consequences of the malfunction.
Sometimes the FUSION FLTV-32T22 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 the failure of the CVB32005 Common Power Module. If it is working properly, you need to check the processor batteries on the SSB (Main Board). In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself for no reason that should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If the FUSION FLTV-32T22 TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the ST3151A05 panel is likely. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the power supply unit (power supply) for an overstated ESR.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of the contact connections in the rulers and connectors.
It is impossible to detect a break in the line of LEDs without disassembling the panel with a simple multimeter. LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes.
Diagnostics and repair of the CV9202H-TPW 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.
Attention to the owners! Attempts to self-repair the FUSION FLTV-32T22 TV are not recommended by the manufacturer and can lead to serious negative consequences!

The appearance of the power supply
Main features of the FUSION FLTV-32T22 device:
Installed matrix (LED panel) ST3151A05.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the OB3350CP PWM controller.
The necessary supply voltages for all nodes of the FUSION FLTV-32T22 TV are generated by the CVB32005 power module or its analogs using AP3105NV microcircuits (PWM SOT23-6 GKO).
MainBoard - the main board (motherboard) is a CV9202H-TPW module, using SPI FLASH chipsets: 25Q64 and others.
The ST03WS-2A-E tuner provides TV reception and channel tuning.

Attention! The F3ION FLTV-32T22 LED TV panel ST3151A05 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.
