General repair guidelines for TV LCD LED
Repair of electronic equipment usually begins with its external inspection and diagnosis of the malfunction. In this case, you should inspect all the internal elements of the V1N08 chassis, as well as the external chassis. Specific external damage to some elements can sometimes indicate further actions to determine the malfunction of the TV and localization of the defect before the necessary measurements are taken. In some cases, faulty elements can be seen with the naked eye, for example, carbonized resistors or swollen metal-ceramic capacitors, or electrolytic in rectifier filters. Ring cracks formed in the soldering of the terminals of transformers or heating elements of the circuit are also frequent sources of many malfunctions with a variety of external manifestations.
Sometimes the FUSION FLTV-28C10 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). In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should be started 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.
In most cases, key breakdowns in switching power supplies (SMPS) do not occur for no reason and you should look for other faulty circuit elements that could provoke a defect. This can be dried electrolytic capacitors in the primary circuit, and faulty damper elements, as well as dangling resistors or punched semiconductor elements in the stabilization circuits. Possible defective PWM chip from the manufacturer.
If the FUSION FLTV-28C10 TV does not have an image, but there is sound, the malfunction should be sought in the power converter of the backlight (LED driver). 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. It is necessary to observe all necessary precautions when disabling the protection of the LED driver during diagnostics and not to leave it disabled after the repair is completed.
Repair or diagnostics of the CV59SH-D32 motherboard should begin by checking the stabilizers or power converters of its chips. If necessary, update the software (software). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - CPU: TSUMV59XUS-Z1, SPI FLASH: 25Q32 and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
Attention to the owners! Attempts to self-repair the FUSION FLTV-28C10 TV are not recommended by the manufacturer and can lead to serious negative consequences!

In case of failures in Winbond's SPI FLASH software, we recommend that you replace the chip itself with a new one. Sometimes Winbond microcircuits can recover for some time after high-temperature exposure, for example, heating with a soldering station or a lighter, which is sometimes enough to read its contents.

Main features of the FUSION FLTV-28C10 device:
Installed matrix (LED panel) ST2751A01-3 or MT3151A05 or CX315DLEDM.
The matrix control uses the Timing Controller (T-CON) ST2751A01-3-XC-2 ;.
To power the backlight LEDs, a converter is used, combined with the CV59SH-D32 main board, controlled by the BIT3267 PWM controller. As power elements of the LED driver, keys of the type ME15N10-G are used.
The power module is combined with the MainBoard and is made according to the scheme of a flyback AC / DC voltage converter using PWM SOT23-6 - LD7536G (L xxP36R) microcircuits and MDF7N60B type power switches.
MainBoard - the main board (motherboard) is a CV59SH-D32 module, using CPU chips: TSUMV59XUS-Z1, SPI FLASH: 25Q32; SOUND: APA2614 and others.
The 5156 (RGA) tuner provides TV reception and channel tuning.

An output for connecting headphones is provided. To connect a computer or laptop to this TV model, a VGA (D-Sub 15) connector is used on the TV case, this interface supports resolutions: 1360x768.
Attention! The F2ION FLTV-28C10 LED TV panel ST2751A01-3 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.
