General repair guidelines for TV LCD LED
Repair of the FUSION FLTV-24W9D TV should begin with a careful external examination of all its components and modules. Sometimes, based on visible changes in the components of the device, it is possible to draw some conclusions and decide on the direction of further troubleshooting even before the necessary measurements are taken. 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 solders will help the master to guess the causes and possible consequences of the malfunction.
If the TV does not turn on, no indicators on its front panel are lit or blinking. Also, if the TV does not respond to the remote control and buttons, does not make any sounds or any signs of operability when turned on, there is a certain probability that the power module is defective and needs repair. Sometimes with similar manifestations, a problem can only occur in the absence of standby power. 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 cut off, then it is necessary to check the diodes of the rectifier bridge and the key transistor of the converter for a breakdown of the PN junctions, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
Mos-Fet keys used in switching power supplies (SMPS) rarely fail for no reason to look for when checking other circuit elements. Often the breakdown is caused by malfunctions of electrolytic capacitors or semiconductor elements in the primary circuit, or by a break in the resistors in the stabilization circuits. The PWM controller chip may also cause a breakdown of the power switch of the converter.
If, when you turn on the TV, the image appears and immediately disappears, or is absent initially when you turn on, but the sound is there and other functions work, there is a high probability of a malfunction of the LED driver (power converter for the backlight LEDs of the TC236F101 panel).
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.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the circuit of the LED lines without disassembling the panels using a tester or a multimeter. To open all PN junctions connected in series, a voltage of the order of several tens of volts is required, and ideally, a current source.
If the CV7168L-A motherboard is faulty, first of all it is necessary to check all the linear stabilizers and power converters of its chips, and also, if necessary, update the software (software). Sometimes you can check the health of MB only by replacement.
In some cases, chip repair may be required to repair the MB (SSB) board - SPI Flash: 25Q32; to new or obviously serviceable. In cases where BGA technologies are used, defects are usually localized by the heating method.If you suspect a malfunction of the F21WT-3BAR-E tuner, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary voltage levels at the corresponding terminals of the tuner.
Owners of the FLTV-24W9D TV are recommended to repair only qualified specialists with experience! Self-repair attempts without the appropriate knowledge and skills can lead to serious negative consequences!

Attention! The TC236F101 panel of the FUSION FLTV-24W9D 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.
