General recommendations for repairing TV LCD
FUSION troubleshooting and repair with B.SPC81B-1 9245 chassis, as well as other electronic devices, is recommended to start with an external examination of the external and internal elements. 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. Swollen electrolytic or cermet capacitors, charred resistors, ring cracks in the soldered terminals of the elements - all this can significantly help the master to determine the causes and consequences of the malfunction of the TV.
If the FUSION FLTV-19W6 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. When diagnosing and repairing the power supply, first of all, replace the swollen filter capacitors of the secondary rectifiers and check the fuse and, if it is broken, it is necessary to identify the cause. Often in such cases, an avalanche (thermal) breakdown is detected in the power semiconductor elements of the module — rectifier diodes and transistors in the primary circuit.
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-19W6 TV does not have an image, but there is sound, the malfunction should be sought in the power converter of the backlight (inverter). 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 an overstated ESR. It is necessary to take into account that in cases of inverter protection shutdown (in order to be able to diagnose) there is a risk of failure of the inverter power elements and take special care. After carrying out repairs, the protection circuit must be restored for further safe operation of the TV.
On the B.SPC81B-1 9245 motherboard, in case of a malfunction, you should first check the performance of all the stabilizers or power converters of the microcircuits and, if necessary, update the software (software). When repairing an MB board, you need to check its components TDA1517P, TDA9886TS. Defective items should be replaced. If BGA chips are installed, their malfunction is usually localized by heating. If chips with BGA soldering technology are used, a problem in its implementation is detected by the local heating of the chip.
Once again, remind users! Attempts to independently repair the FUSION FLTV-19W6 TV without the appropriate qualifications and experience can lead to its complete non-repairability!

CV7050LA can be used in TVs:
BBK LT1902S (Panel M190A1-P0A), BBK LT2202S (Panel M216H1-P01), BBK LT2428HD (Panel V236H1-P01 HK236WLCM-CH03H), BBK LT2428S (Panel V236H1-P01), FUSION FLTV-19W6 (Panel M190A1-P0A), IZUMI TL26H615B (Panel M260TWR1).
Main features of the FUSION FLTV-19W6 device:
Installed matrix (LCD panel) M190A1-P0A.
The matrix control uses the Timing Controller (T-CON) M190A1-L0A-X + C.
To power the backlight, a converter is used, combined with a power supply, controlled by a BIT3713 PWM controller. As power elements of the inverter, keys of type 4606 are used.
The necessary supply voltages for all nodes of the FUSION FLTV-19W6 TV are generated by the LK-PI190414CF power module, or its analogs using GR8876 microcircuits.
MainBoard - the main board (motherboard) is a CV7050LA module, using TDA1517P, TDA9886TS and others.
The tuner F21WT-3BAR-E // ET-6T1E-LF-108W-A provides the reception of television programs and tuning to channels.
