General repair guidelines for TV LCD LED
A malfunction of the power supply is often manifested corny - the TV does not turn on, does not make any sounds, does not light up and does not blink with any indicators. It is advisable to start the troubleshooting of the power supply module by checking the condition of the electrolytic capacitors of the rectifier filters and the mains fuse. Defective capacitors should be replaced. If the mains fuse is broken, it is necessary to check first of all the power semiconductor elements - rectifier diodes and transistors, which are often found in such a state of 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 the semiconductor elements of the binding of the IC_Power PWM regulator chip are subject to verification, which it is desirable to verify by replacement.
If there is no image when you turn on the FUSION FLTV-23L18B, or it appears and immediately disappears, but there is sound, most likely there is a malfunction in the backlight LED circuit of the LTA230AP01 panel, or in the LED node of the driver-converter of their power supply.
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 LED line for breaks without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally, a current source. Having disassembled the panel, it is necessary to check each LED separately. Chinese multimeters, as a rule, light up a single 3-volt LED in the forward direction. In the case of using dual 6-volt LEDs, the PN junction of its protective zener diode can serve as a health indicator. In faulty LEDs, the zener diode will either be cut off or broken into short-circuit.
If the motherboard 40-MS8200-MAD2XG (V8-MS82AGS-LF1V108) is faulty, first of all you need 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.
Board repair and replacement of CPU chips MST6E182VS-LF-Z1, Flash GD25Q32 are carried out with the necessary equipment, and the corresponding element base. Malfunctions associated with the application of the soldering technology of the BGA processor can be localized by the heating method.
If there is no reception of television channels, but the TV is working properly from external devices, first of all you need to check the power supply of the TDQ-3CB tuner and update the software. The pulses from the I2C bus must be monitored using an oscilloscope.
It should be remembered! Attempts to repair the FUSION FLTV-23L18B 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!

Attention! The panel of the FUSION FLTV-23L18B LED TV LTA230AP01 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.
