General repair guidelines for TV LCD LED
Possible manifestations of defects
- FUSION FLTV-22W8 does not turn on and does not show any signs of performance at all. Does not blink indicators and does not respond to control buttons.
Often in such cases, the 569KN0120D power module is faulty. It is necessary to measure its output supply voltage, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
In case of breakdowns in the secondary circuits, the converter, as a rule, can emergency work in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse usually breaks.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode, or cause the maximum current or voltage to be exceeded. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM), in the absence of external damage and a short circuit between the terminals, are checked by replacing with obviously good ones.
- There is no image, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
In some of these cases, the malfunction is caused by a lack of backlighting on the display. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
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. Then it is necessary to open the panel and check each LED separately with a multimeter. If the capabilities of your multimeter do not allow you to open the LED in the forward direction or dual LEd are used, then the PN junction of the emergency zener diode can indirectly serve as a health indicator. In case of LED-a malfunction, the zener diode PN junction will either be cut off or broken into short-circuit.
- The indicator blinks or lights up constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the 569KC0201A motherboard should begin by checking the stabilizers and power converters needed to power the chips and matrix. If necessary, update or replace the software (software). Board repair and chip replacement SPI FLASH: MX25L3206E are made with the necessary equipment, and the corresponding hardware base. Faults associated with the use of BGA processor soldering technology can be localized by the heating method.
If there is no reception of television channels, but the TV works properly from external devices, first of all it is necessary to check the voltage of the tuner F41CT-2B-E and update the software. The pulses from the I2C bus must be monitored using an oscilloscope.
Once again, remind users! Attempts to independently repair the FUSION FLTV-22W8 TV without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

Main features of the FUSION FLTV-22W8 device:
Installed matrix (LED-panel) CLAA215FA04.
To power the backlight LEDs, a converter is used, combined with a power supply.
The formation of the necessary supply voltages for all nodes of the FUSION FLTV-22W8 TV is carried out by the 569KN0120D power module, or its analogs.
MainBoard - the main board (motherboard) is a 569KC0201A module, using SPI FLASH chips: MX25L3206E and others.
The F41CT-2B-E tuner provides TV reception and channel tuning.

FUSION FLTV-22W8 TV with CLAA215FA04 LCD display, diagonal size 22 "(56 cm) 16: 9 format. The required brightness of the screen is 250 cd / m² LED backlight LED. Contrast, as the ratio of maximum brightness to minimum, is 1000: 1. Dynamic contrast ratio of 4000: 1 is achieved by special control of the LEDs. The technology for making the screen of this TV model uses LED LED backlighting. The design and technical capabilities of the TV provide for viewing broadcasts and films in high quality HD at a resolution of 1920x1080 pixels in a graphic resolution of 1080p ( Full HD). The input high-frequency or video signal can be processed in analogue systems PAL, SECAM, NTSC. Graphic processing and digital signal generation occurs in the standards 480i, 480p, 576i, 576p, 720p, 1080i, 1080p. Supported media file formats: MP3, Jpeg.
The power of the acoustic system of sound 6 W (2x3 W) provide two speakers. The audio processing system NICAM STEREO is used.
The external interface (communication with other devices) is supported by standard input and output connectors: antenna input (RF), AV, audio x2, component, VGA, HDMI x2, USB. An output for connecting headphones is provided. To connect a computer or laptop to this TV model, a VGA (D-Sub 15) connector is used on the TV case, this interface supports resolutions: 640x480, 800x600, 1024x768.
The power consumed by the TV working in the network mode is 30 watts.

Attention! The CLAA215FA04 panel of the FUSION FLTV-22W8 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.
