General repair guidelines for TV LCD LED
Repair of the FUSION FLTV-19T9D TV should begin with a careful external examination of all its components and modules. Often, by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. Experienced repairmen are often aware of the causes of the defect and possible consequences, for example, from ring cracks in the soldering of the leads of the elements, as well as from swollen capacitors or resistors burnt to coal dust and other external indirect signs.
In cases when the FUSION FLTV-19T9D TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink, and there are no sounds and no signs of operability when turning on, the power module is most likely faulty or there is no power processor on the motherboard (a typical defect of some models of FUSION TVs). In the absence of swollen filter capacitors of the secondary rectifiers, the diagnostics of the power supply should begin 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.
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-19T9D TV does not have an image, but there is sound, a malfunction in the LED backlight circuits of the TB190B1Z1 panel is likely. It is also necessary to check the serviceability of the electrolytic capacitors of the filter of the secondary rectifiers of the BP (power supply) for an overstated ESR.
In most cases of lack of backlight, there is a need 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 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.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
In cases of complex repairs of MB (SSB) and in the presence of the necessary skills and equipment, sometimes it may be necessary to replace its Cpu: MST6M181VS, Spi Flash: 25Q32, Ram: Winbond W2925G6JH-4, Audio: YD1517P, and other possible malfunctioning components. Malfunctions associated with the application of BGA soldering technologies are usually easily diagnosed by the heating method.
If you suspect a malfunction of the AFT7 / W110G QINGJIA tuner, first of all, you need to make sure that the voltage of the varicaps (30-33V) is on the corresponding output of the tuner, as well as other voltage supplying it.
Owners and users of the FUSION FLTV-19T9D 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-19T9 V3L06, Main: CV182_B, Panel: LM185WH2(TL)(A1)
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-19T9 V1K12, Main: CV181L-A
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-19T9D, Main: CV181L-A, Panel: TB190B1Z1
If a failure occurs in the Winbond SPI FLASH software, we recommend that you replace the chip with a new one. Frequently 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 MainBoard
The appearance of the MainBoard CV181L-A is shown in the figure below:
CV181L-A
As part of the CV181L-A motherboard, a multifunctional processor MST6M181VS is used, combined with a scaler (video controller-scaler). It is advisable to start the MainBoard repair by checking the power supply of the Stand-by mode, which is implemented using a separate 3.3V linear stabilizer. In the operating mode, it is necessary to check the operability of linear stabilizers or voltage converters necessary to provide power to the processor nodes: 1.2V, 2.5V, 3.3V. A voltage of 2.5 V is required to power the DDR W9425G6JH-4 random access memory. If there is no image, but the display backlight is working properly, it is advisable to measure the power of the 5V or 12V LCD panel, depending on the type of panel used, directly on the LVDS connector. If the TV does not exit Stand-by mode, does not respond to the remote control and control buttons, you should check the 3.3V power at pin 8 of the SPI FLASH chip, it may be necessary to update its software.CV181L-A can be used in TVs:
FUSION FLTV-19T9D (Panel TB190B1Z1), FUSION FLTV-22T9D (Panel HM215WU1-500), HYUNDAI H-LED22V16 (Panel M215HW01 V.B), HYUNDAI H-LED15V6 (Panel LP156WD1 (TL)(A1)), SUPRA STV-LC2277FLD (Panel HK215LEDM-BH 1H), SUPRA STV-LC2425WL (Panel M240HW02 V.1), SUPRA STV-LC1677WL (Panel 720p HD 1366x768).
The appearance of the power supply
Main features of the FUSION FLTV-19T9D device:
Installed matrix (LED panel) TB190B1Z1 or LM185WH2 (TL) (A1).
The matrix control uses the Timing Controller (T-CON) 6870S-1073A.
The LED driver HTX-LP220103 is used to power the backlight LEDs.
The necessary supply voltages for all nodes of the FUSION FLTV-19T9D TV are generated by the DC12030011A power module or its analogs using OB2263 microcircuits (PWM SOT23-6).

Attention! The TB190B1Z1 panel of the FUSION FLTV-19T9D 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.
