General recommendations for repairing TV LCD
Diagnostics of malfunctions and repairs of the FUSION FLTV-3218B, as well as other electronic devices, is recommended to begin with an external examination of the external and internal elements. Visible damage to elements can sometimes indicate the direction of the search for a defect even before the necessary measurements are taken. 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 control lights are on or blinking, there are no sounds when you turn on, and there is not the slightest sign of operability - the most likely malfunction is in the power module. 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-3218B has no image, but there is sound and the TV is controlled by the remote control, a malfunction in the display backlight nodes is likely. The lamps or the power converter - inverter 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 inverter, and check the LCD lamps by connecting external and obviously serviceable for diagnosis to the connectors. All necessary precautions must be observed when disabling the inverter protection during diagnostics and not leaving it disconnected after the repair is completed.
Repair of the CV182H-F motherboard should begin with the diagnosis and verification of all linear stabilizers and power converters of its microcircuits. Sometimes it may be necessary to update the software (software) - flashing FLASH or EEPROM. When repairing an MB board, you must check its CPU components: CAT6354CQ; SPI Flash: WINB25Q32 ;. Defective items should be replaced. If chips with BGA soldering technology are used, a problem in its implementation is detected by the local heating of the chip.
It is necessary to remember to users that attempts to independently repair a FUSION FLTV-3218B TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-3218B, Main: CV182H-F, Panel: T315CK06-PW1
The appearance of the MainBoard CV182H-F is shown in the figure below:
CV182H-F
The CV182H-F motherboard uses the MST6M182VG processor, combined with a scaler and installed using BGA technology.
It is advisable to start this type of MainBoard repair 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.
CV182H-F can be used in TVs:FUSION FLTV-32H18 (Panel T315CK07-BW2), FUSION FLTV-3218B (Panel T315CK06-PW1), SUPRA STV-LC3215W STV-LC3215WD (Panel LTA320AP29), SUPRA STV-LC4215DF (Panel T420HW05 V.0 ).
The appearance of the power supply
Main features of the FUSION FLTV-3218B device:
Installed matrix (LCD panel) T315CK06-PW1.
To power the backlight, a converter is used, combined with a power supply unit, controlled by the OB3316QP PWM controller.
The necessary supply voltages for all nodes of the FUSION FLTV-3218B TV are generated by the LK-PI320302A power module or its analogs using FAN7930 microcircuits and 12N50 type power switches.
MainBoard - the main board (motherboard) is a CV182H-F module, using CPU chips: CAT6354CQ; SPI Flash: WINB25Q32; HDMI: CAT6354CQ, Audio: TPA3110LD2 and others.
The tuner CDT-3SP5I2-37 provides the reception of television programs and tuning to channels.
FUSION FLTV-3218B TV with T315CK06-PW1 LCD, 32 "(81 cm) diagonal size in 16: 9 format. 400 cd / m² screen brightness is provided by CCFL (EEFL) fluorescent lamps. Contrast as the ratio of maximum brightness to the minimum is 1600: 1. Dynamic contrast ratio of 80,000: 1 is ensured by special control of the backlight operation depending on the illuminance of sections in the plot. the video signal can be processed in analog systems PAL, SECAM, NTSC.
