General repair guidelines for TV LCD LED
Possible malfunctions
- FUSION FLTV-24H100T does not turn on, the indicators on the front panel do not light or flash. The TV does not respond to the control buttons and the remote control.
The malfunction in such cases should be sought in the elements of the power source - the network voltage converter (AC / DC), which is located on the MainBoard TP.S512.PA63 main board. It is necessary to measure its output voltages and, if they are absent, to check the short circuit probability in the converters power switches and rectifier diodes.
In the event of a breakdown 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 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 provoke an excess of the maximum current or voltage. 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) LD5530, in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good.
- There is no image, there is sound, it responds to the remote control, the channels are switched. In some cases, the image appears when you turn on and immediately disappears.
Failure in most such cases is detected in the nodes and backlight elements of the LED panel. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
It is impossible to check the LED line for breaks without disassembling the panel with a multimeter or tester. For these purposes, it is necessary to open all series-connected PN junctions and a voltage of the order of tens of volts will be required, and ideally, a current source. Having disassembled the panel, it is necessary to check each LED separately. Chinese multimeters, as a rule, light up a single 3-volt LED in the forward direction. In the case of using dual 6-volt LEDs, the PN junction of its protective zener diode can serve as a health indicator. In faulty LEDs, the zener diode will either be cut off or broken into short-circuit.
- The TV does not turn on, the indicator signals standby or working mode, or blinks.
Repair or diagnostics of the TP.S512.PA63 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). Sophisticated MB board repair (SSB) is in some cases possible and practiced by repairmen. To do this, check and, if necessary, replace elements S2T512, 25Q64, CD1517CP. BGA chip malfunctions are usually easy to detect by warming up.
In the absence of tuning to the channels of on-air or cable television, you should make sure that the software is correct, as well as in accordance with the ratings of the supply voltage at the terminals of the XF-3SDT-H tuner (R840). It is also necessary to check the presence of pulses of data exchange between the tuner and the processor via the I2C bus using an oscilloscope.
Attention! For users and owners of FLTV-24H100T TVs who do not have the appropriate qualifications, knowledge and experience, we strongly recommend against attempting self-repair in order to avoid negative consequences that could lead to complete non-repairability of the device.

Main features of the FUSION FLTV-24H100T device:
Installed matrix (LED-panel) CM238C01.
To power the backlight LEDs, a converter is used, combined with the main board TP.S512.PA63, controlled by the SN51DP PWM controller. As the power elements of the LED driver, keys of the type ME15N-10G are used.
The power module is combined with the MainBoard and is made according to the flyback AC / DC voltage converter circuit using LD5530 chips.
MainBoard - the main board (motherboard) is a TP.S512.PA63 module, using chips S2T512, 25Q64, CD1517CP and others.
Tuner XF-3SDT-H (R840) provides the reception of television programs and tuning to channels.
FUSION FLTV-24H100T TV with CM238C01 LCD, 23.8 "(60 cm) diagonal size of 16: 9 format. The required screen brightness of 240 cd / m² is provided by LED backlighting. Dynamic contrast ratio of 80000: 1 is achieved by special control of the LEDs. The LED panels of this TV are equipped with end LED backlighting - Edge LED.The design and technical capabilities of the TV include viewing programs and movies in high quality HD at a resolution of 1920x1080 pixels in a graphic layout according to the standard 1080p (Full HD). Supported media file formats: MP3, MPEG4, MKV, JPEG.
The power of the speaker system of sound 5 W (2x2.5 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), component, VGA, HDMI, USB. An output for connecting headphones is provided.
A digital tuner is capable of receiving television channels in the DVB-T MPEG4, DVB-C, DVB-T2 standards.
Overall dimensions: 614x425x134 mm.
Attention! The panel of the F23ION FLTV-24H100T LED TV CM238C01 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.
