General repair guidelines for TV LCD LED
Possible malfunctions
- The FUSION FLTV-30B100 TV does not turn on and does not show any signs of turning on, it does not respond to the control buttons or to the remote control.
In this case, the main power source, the AC / DC network voltage converter, whose elements in this model are located on the MainBoard TP.V56.PB816 general board, may turn out to be faulty. It is necessary to measure its output voltages, and in case of their absence, check the serviceability of power switches (70R600 TO-252) of converters and rectifier diodes for a short circuit probability.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during short circuit in the elements of the primary circuit, the mains fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, in the power supply circuit of a PWM controller, in frequency-setting or damping circuits, as well as in Negative Stabilization Feedback. PWM SOT23-6 PWM chips are usually checked by replacing with new ones, or obviously working.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
As a rule, in this case, the LED backlight turns out to be faulty. Often the cause is a malfunction of the LEDs (open circuit, short circuit ...), or the connectors of the strips (strings), less often the LED driver is malfunctioning.
It is impossible to check the line of series-connected LEDs without a special current source, and for this purpose it is not safe to use any voltage sources above 12V. Then it remains only to open the panel and check each LED separately. Usually, Chinese 9V-powered multimeters light up a single 3-volt LED, if you connect the probes in the forward direction, the red probe to the anode, and the black to the cathode. In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the TP.V56.PB816 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 replacement of CPU chips: TSUMV56RUU-Z1, SPI Flash: 25Q32CSIG are carried out with the necessary equipment, and the corresponding element base. Faults associated with the use of BGA processor soldering technologies can be localized by the heating method.
If there is no reception of television channels, but the TV is working properly from external devices, first of all, check the voltage of the NoName tuner and update the software. The pulses from the I2C bus must be monitored using an oscilloscope.
Users and owners of TVs must remember that attempts to repair the FUSION FLTV-30B100 TV independently without the appropriate qualifications and necessary experience can lead to serious negative consequences!
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-30B100 V1S07, Main: TP.V56.PB816, Panel: D28-F2000
The appearance of MainBoard TP.V56.PB816 is shown in the figure below:TP.V56.PB816
Main features of the FUSION FLTV-30B100 device:
Installed matrix (LED-panel) D28-F2000.
To power the backlight LEDs, a converter is used, combined with the main board TP.V56.PB816, controlled by the SN510P PWM controller. As power elements of the LED driver, keys of the TO-252 type are used.
The power module is combined with the MainBoard and is made according to the scheme of a flyback AC / DC voltage converter using PWM SOT23-6 microcircuits and power switches of the 70R600 TO-252 type.
MainBoard - the main board (motherboard) is a TP.V56.PB816 module, using CPU chips: TSUMV56RUU-Z1, SPI Flash: 25Q32CSIG and others.
The NoName tuner provides television reception and channel tuning.
FUSION FLTV-30B100T TV with a D28-F2000 LCD display, diagonal size 28 "(71 cm) in 16: 9 format. The required screen brightness of 220 cd / m² is provided by LED backlighting. Dynamic contrast ratio of 80000: 1 is achieved by special control of the LEDs The LED-panel of this TV is equipped with LED end-lighting - Edge LED.

Attention! The D28-F2000 panel of a FUSION FLTV-30B100T 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.
