General repair guidelines for TV LCD LED
The FUSION FLTV-16T9 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. Electrolytic capacitors of filters with a swollen body, as well as ring cracks or a layer of coal on burned-out resistors formed in the soldered terminals of the heating elements, sometimes tell the repairman the causes of the malfunction and possible consequences.
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 processor power, which is typical for certain FUSION models. 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.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself without any reasons that should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
If the FUSION FLTV-16T9 does not have an image, but there is sound and the TV is controlled by the remote control, a malfunction in the backlight circuits of the B156XTN02 panel is likely. The LEDs or the power converter - LED driver may be faulty. Often in such cases, when you turn on the TV, an image appears and immediately disappears. First of all, it is necessary to verify the operability of the electrolytic capacitors of the rectifier filter supplying the LED driver, and check the LEDs, connecting obviously known good diagnostics.
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 the contact connections in the rulers and connectors.
When diagnosing, it is necessary to take into account that it is impossible to check the open in the chain of LED lines without disassembling the panels using a tester or 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.
Diagnostics and repair of the motherboard T.VST59.62 is carried out by checking the operability of the stabilizers or power converters of the module chips. In some cases, a software update is required.
In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - CPU: TSUMV59XE, FLASH: 25Q32. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
If you suspect a malfunction of the CDT-3NP5I1-10 tuner, first of all, you need to make sure that there is a varicap supply voltage (30-33V) on the corresponding output of the tuner, as well as other voltage supplying it.
Owners and users of the FUSION FLTV-16T9 TV must remember that self-repair without special knowledge, skills and qualifications can be fraught with negative consequences that can lead to complete non-repairability of the device!

FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-16T9 V4M03, Main: T.VST59.62, Panel: B156XTN02
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.
Repair MainBoardThe appearance of MainBoard T.VST59.62 is shown in the figure below:
T.VST59.62
It is advisable to start repairing the T.VST59.62 motherboard based on the TSUMV59Xxx multifunction processor by checking the performance of linear voltage stabilizers or voltage converters necessary to provide power to the processor nodes - 1.2V core power, 1.8V DDR memory and Stand-by 3.3V mode . If there is no image, but the display backlight is working properly, you should check the power supply voltage of the LCD panel 5V or 12V, depending on the type of panel used.
