General repair guidelines for TV LCD LED
Repair and diagnostics of any electronic device, in particular FUSION FLTV-24C10, it is advisable to start with a careful external examination of internal and external elements. 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. In most cases, the repairman can guess the causes of the defect and possible consequences from the characteristic signs of typical TV defects, for example, ring cracks formed in the soldering of the element leads, swollen rectifier filter capacitors, charred resistors and other circuit elements.
Sometimes the FUSION FLTV-24C10 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 need to check the processor batteries on the SSB (Main Board). Diagnostics and repair of the common power supply should always begin with a check of the mains fuse and the condition of the electrolytic capacitors of the secondary rectifier filters. Defective and swollen capacitors should be replaced with new ones. If the fuse is broken, it is advisable to check for a breakdown, first of all, all the power semiconductor elements of the converter and the diode bridge of the rectifier network, as well as the large electrolytic capacitor of the filter of the rectifier network.
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 the FUSION FLTV-24C10 TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the LVW230SSOT E1 V2 panel is likely. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the PSU (power supply) for excessive 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 contact connections in the rulers and connectors.
It should be remembered that it is not possible to determine the break in the LED lines without disassembling the panels using a tester or multimeter without an additional device, for example, a current source. To open all PN junctions connected in series at once, a voltage of several tens of volts may be required.
In cases of attempts to repair the TP.MS18VG.P77 MS82PT motherboard, it is necessary to check the operation of the stabilizers or power converters of its microcircuits and, if possible, update the software (software). BGA chips can in most cases be diagnosed by local heating.
Board repair and replacement of CPU chips: MST3M182VGC-LF-TZ, FLASH: GD25Q32BSIG 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.
Attention to the owners! Attempts to self-repair the FUSION FLTV-24C10 TV are not recommended by the manufacturer and can lead to serious negative consequences!
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-24C10, Main: TP.MS18VG.P77 MS82PT, Panel: LVW230SSOT E1 V2
If a failure occurs in the SPI FLASH software from Winbond, we recommend that you replace the chip with a new one. Often, unreadable Winbond microcircuits can temporarily restore their functionality after a strong temperature exposure, for example, heating with a soldering station or a lighter. Sometimes this is enough to read its regular contents.

Attention! The LVW230SSOT E1 V2 panel of the FUSION FLTV-24C10 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.
