General repair guidelines for TV LCD LED
The FUSION FLTV-22W6 TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Sometimes, based on visible changes in the components of the device, it is possible to draw some conclusions and determine the direction of further troubleshooting even before the necessary measurements are taken. If ring cracks are detected in the soldering of the terminals of the elements or dangling connecting tracks, swollen capacitors or charred resistors - all this can be characteristic signs of the causes or consequences of an already known typical malfunction.
If the FLTV-22W6 TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power module. In some cases, there may be a malfunction only in standby power. In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should begin by checking the fuse and, if it is broken, it is first necessary to check all the power semiconductor elements of the primary circuit - diodes and transistors for the possibility of an avalanche or thermal breakdown.
It should be borne in mind that in the practice of repair it is extremely rare that key transistors in switching power supplies (SMPS) fail for no reason that should be sought by checking other components, for example, a breakdown of the key can provoke faulty elements of the damper circuits, or dried electrolytic capacitors or dangling primary resistors BP circuits involved in the stabilization process. In this case, all semiconductor elements of the binding of the PWM controller microcircuit are subject to verification, which it is desirable to verify by replacement.
If there is no image when you turn on the FUSION FLTV-22W6, or it appears and immediately disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the CLAA215FA panel, or in their power converter.
In most cases of lack of illumination, it becomes necessary to disassemble the panel in order to check the LEDs, connectors, loops and all contact connections. If one or several LEDs does not work in one line, therefore, they are broken and should be replaced.
It is impossible to check the line of series-connected LEDs without a special current source, and for this purpose it is not safe to use any voltage sources above 12V. Then it remains only to open the panel and check each LED separately. Usually, Chinese 9V-powered multimeters light up one LED slightly if you connect the probes in the forward direction, the red probe to the anode, and the black to the cathode.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace the SPI Flash elements: EN25T80_U11; EEPROM: 24C32_U13; . BGA chip malfunctions are usually easy to detect by warming up.
If the TV works normally from external devices, but does not tune into television channels, the tuner ET6T1E-LF-108W-A may be malfunctioning. In such cases, first of all, you should make sure that there are supply voltages at its corresponding terminals. Sometimes the cause of the inoperability of the tuner may be a software failure.
Attention to the owners! Attempts to self-repair the FUSION FLTV-22W6 TV are not recommended by the manufacturer and can lead to serious negative consequences!

Main features of the FUSION FLTV-22W6 device:
Installed matrix (LED-panel) CLAA215FA.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by a BIT3713 PWM controller. As the power elements of the LED driver, keys of type 4606 are used.
The necessary supply voltages for all nodes of the FUSION FLTV-22W6 TV are generated by the LK-PI190414CF power module, or its analogs using GR8876 microcircuits.
MainBoard - the main board (motherboard) is a B.SPC81B-1 module, using SPI Flash chips: EN25T80_U11; EEPROM: 24C32_U13; and others.
The ET6T1E-LF-108W-A tuner provides TV reception and channel tuning.
