FUSION FLTV-19T9
General recommendations for repairing TV LCD
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 V3L06 chassis, as well as the external chassis. 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. Elements with visible damage, for example, capacitors swelled up after boiling the electrolyte, charred resistors in certain nodes of the circuit, as well as ring cracks in solders will help the master to guess the causes and possible consequences of the malfunction.
If the FUSION FLTV-19T9 does not turn on, no control lights on the front panel light up or blink, therefore, there is a very high probability of a power module malfunction. In some cases, only the processor power regulator may be faulty. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
If the FUSION FLTV-19T9 does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction of the display backlight, or their power converter - inverter. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the inverter itself, including in the secondary rectifier of the main PSU. It should be remembered that when protection is disabled in order to diagnose a malfunction, there is always a risk of failure of the power elements of the inverter. After repair, it is necessary to restore all standard converter protection circuits.
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 attempts to repair the MB (SSB) board, it is necessary to check the serviceability of its elements - SPI FLASH W25Q32 which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
Attention to the owners! Attempts at self-repair of the FUSION FLTV-19T9 TV are not recommended by the manufacturer and can lead to serious negative consequences!
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
If a failure occurs in the SPI FLASH Winbond software, we recommend that you replace the chip with a new one. In addition, faulty Winbond microcircuits can sometimes recover for a while after being heated by a soldering station or even a lighter, which is enough to read its regular contents.
Repair MainBoardThe appearance of the MainBoard CV182L-B is shown in the figure below:
The CV182L-B motherboard uses the MST6M182VG processor, combined with a scaler and installed using the BGA technology.
It is advisable to begin repairing this type of MainBoard by checking the voltage converters and linear stabilizers necessary to provide power to the processor nodes: 1.2V, 2.5V, 3.3V. Check the power supply of the 5V or 12V LCD panel, depending on the type of panel used, it is advisable directly on the LVDS connector. If, in the presence of the necessary supply voltage, the TV does not exit Stand-by mode, does not respond to the remote control and control buttons, the SPI Flash software should be updated.
CV182L_B can be used on TVs:
FUSION FLTV-22T9 (Panel TB215WU3), FUSION FLTV-19T9 (Panel LM185WH2(TL)(A1)), FUSION FLTV-19T9D (Panel TB190B1Z1), SUPRA STV-LC1625WL (Panel BT156GW01 V.A), SUPRA STV-LC1925WL (Panel MT185GW01 V.1), SUPRA STV-LC19810WL (Panel TB190B300-A), SUPRA STV-LC2237FL (Panel TP215FT01), SUPRA STV-LC1625WLD (Panel B156HW02), SUPRA STV-LC1937WL (Panel LM185WH2-TLA1).

Attention! The TB190B1Z1 panel of the FUSION FLTV-19T9 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.
