General repair guidelines for TV LCD LED
Possible malfunctions
- The FUSION FLTV-32L32 does not turn on at all. There is no reaction to the remote control and control buttons from the front panel. Indicator lights do not light or flash.
In this case, first of all, you should check the operability of the main power source - the AC / DC network voltage converter, all of whose elements are located on the MainBoard TP.VST59S.PB801 board. It is necessary to measure the output voltages in its secondary circuits, and if they are completely absent, you should check the health of the power switches (TO-220) and rectifier diodes for possible breakdown (short circuit).
In the event of breakdowns in the secondary circuits of the converter, it can usually fail in short circuit mode, and in the event of a short circuit in the power elements of the primary circuit, the mains fuse or current sensor at the source of the key most often breaks.
Mos-Fet power switches, used in switching power supplies, sometimes fail due to a malfunction of any other elements that can put it out of operation in key mode or create an excess of the maximum permissible parameters of the switch. These can be elements supplying the PWM controller, frequency-setting or damping circuits, or negative feedback elements in the stabilization circuit. PWM SOT23-6 PWM controllers, in the absence of visible damage or obvious short-circuit between the terminals, are checked by replacing with new ones, or obviously working.
- There is no image, there is sound, all other functions of the TV work. When turned on, the image may sometimes appear for a second.
As a rule, in this case, the LED backlight turns out to be faulty. The reason for this may be an open circuit in the LED circuit, or a problem in stabilizing their power supply.
It is impossible to detect a break in the line of LEDs without disassembling the panel with a simple multimeter. The LEDs are connected in series and to open their transitions, a voltage of several tens of volts is required. Ideally, a current source is suitable for such purposes. You can open the panel and check each LED separately. Typically, Chinese multimeters light up a single 3-volt LED if you connect the probes in the forward direction to it (red probe to the anode, black to the cathode). In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as a health indicator. 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.VST59S.PB801 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). In cases of attempts to repair the MB board (SSB), it is necessary to check the health of its elements - CPU: TSUMV59XES, SPI Flash: MX25L3205 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).
Owners of the FLTV-32L32 TV are recommended to repair only qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!

The appearance of MainBoard TP.VST59S.PB801 is shown in the figure below:TP.VST59S.PB801
Main features of the FUSION FLTV-32L32 device:
The matrix (LED panel) HK315LEDM-0HNBH is installed.
To power the backlight LEDs, a converter is used, combined with the main board TP.VST59S.PB801, controlled by the SN51DP 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 flyback AC / DC voltage converter circuit using PWM SOT23-6 microcircuits and TO-220 type power switches.
MainBoard - the main board (motherboard) is a TP.VST59S.PB801 module, using CPU chips: TSUMV59XES, SPI Flash: MX25L3205 and others.
The NoName tuner provides television reception and channel tuning.
FUSION FLTV-32L32 TV with HK315LEDM-0HNBH LCD, 32 "(81 cm) diagonal size of 16: 9 format. The required screen brightness of 240 cd / m² is provided by LED backlighting. Dynamic contrast ratio of 100,000: 1 is achieved by special control of the LEDs The LED-panel of this TV is equipped with LED end-lighting - Edge LED. You can view images in high quality HD at a resolution of 1366x768 pixels in the standard for graphic decomposition 720p (HD Ready). 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. Supported media file formats: MP3, MPEG4, MKV, JPEG.
The power of the sound system 12 W (2x6 W) provides two speakers. The audio processing system NICAM STEREO is used.

Attention! The HK315LEDM-0HNBH panel of the FUSION FLTV-32L32 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.
