General repair guidelines for TV LCD LED
The FUSION FLTV-32L41B TV, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. According to some external signs of a change in the state of some elements, it is sometimes possible to make assumptions about the nature of the defect, as well as determine the further direction of the troubleshooting. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the solders of the terminals of transformers or heating elements are found, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
Malfunctions of the power module can be expressed in different ways, for example, the FUSION FLTV-32L41B does not turn on at all and the control lamps on its front panel do not light up and do not blink, there are no signs of operability. It should be noted that with the same external manifestations, the processor power regulator (converter) may be faulty. When repairing the power supply, it is advisable to start the diagnostics by checking the mains fuse and the electrolytic capacitors of the filters of the converter secondary rectifiers. In the event of a fuse breaking, the reason should be sought in the power semiconductor elements of the pulse converter of the main power supply. First of all, it is necessary to check the diodes of the bridge of the rectifier of the mains voltage and the power switch (s) of the converter.
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-32L41B does not have an image, but there is sound, there may be a malfunction of the backlight LEDs of the panel or their power converter. You should also make sure that the electrolytic capacitors of the secondary rectifiers of the common power supply are working.
To check the health of the LEDs and contact connections in their power circuit, it is necessary to disassemble the panel.
An open in the line of LEDs connected in series cannot be detected with a multimeter or tester without disassembling the panel. To open all the transitions, several tens of volts are needed, and it is best to use a current source for such purposes.
In cases of attempts to repair the TP.VST59.P83 motherboard, it is necessary to check the operability 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.
In some cases, to repair the MB board (SSB), it may be necessary to replace the chips - Cpu: TSUMV59XE Spi Flash: W25Q32BV with new or obviously working ones. In cases where BGA technologies are used, defects are usually localized by the heating method.
If you suspect a malfunction of the tuner CDT-3NP5I1-10, first of all, you need to make sure that the voltage of the varicaps (30-33V) is present on the corresponding output of the tuner, as well as other voltage supplying it.
Once again, remind users! Attempts to independently repair the FUSION FLTV-32L41B TV without the appropriate qualifications and experience can lead to its complete non-repairability!

FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-32L41B, Main: TP.VST59.P83
At failures in the software SPI FLASH chip manufacturer Winbond, they can at any time to restore its efficiency after temperature exposure - warm hairdryer soldering station, or even lighter. Usually this is enough to read the regular contents of the software. In such cases, the chip must be replaced with a new one.
Repair MainBoardThe appearance of MainBoard TP.VST59.P83 and voltage measurements at the test points are shown in the figure below:
TP.VST59.P83
The TP.VST59.P83 motherboard is combined with a power module and is an independent device made on the basis of the TSUMV59Xxx multifunction processor. Repair of such a board must begin by checking the power batteries, as well as the operability of the voltage converters and linear stabilizers necessary to provide power to certain processor nodes, in particular: + 1.2V core power, built-in DDR + 1.8V memory, and Stand- by 3.3V. The voltage of the LCD panel 5V or 12V, depending on the type of panel used, must be checked directly on the LVDS connector.
