General repair guidelines for TV LCD LED
Possible manifestations of defects
- The FUSION FLTV-19C10 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.
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.VST59.PA671 main board. It is then necessary to measure its output voltages and, if they are absent, you should check the power switches (60R900P TO-252) and the rectifier diodes of the converters for a short circuit probability.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often 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 chips PWM SOT23-6 LD7530 are usually checked by replacing with new, or obviously working.
- There is no image, there is sound, it is responding to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
Often in such cases, there is no LED backlight. 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.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
- The TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights constantly or blinks.
Repair or diagnostics of the TP.VST59.PA671 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 the CPU elements: TSUMV59XE-Z1, SPI: FLASH W25Q32BV, AUDIO: YD1517P. BGA chip malfunctions are usually easy to detect by warming up.
If there is no reception of television channels, but the TV is working properly from external devices, first of all you need to check the voltage of the R840 tuner and update the software. The pulses from the I2C bus must be controlled with an oscilloscope.
We recommend the owners of the FLTV-19C10 TV for repair only to qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-19C10 V1P11, Main: TP.VST59.PA671, Panel: MT185WHB-N10
The appearance of MainBoard TP.VST59.PA671 is shown in the figure below:TP.VST59.PA671
TP.VST59.PA671 can be used in TVs:
FUSION FLTV-22C10 (Panel M215HTN01.3), FUSION FLTV-24L32 (Panel M236HJJ-P02 Rev C4 HK236WLEDM-CHL4H), SHIVAKI STV-24LED5W (Panel LM240WH1-LE1).
Main features of the FUSION FLTV-19C10 device:
Installed matrix (LED panel) MT185WHB-N10.
The matrix control uses the Timing Controller (T-CON) BOE.
To power the backlight LEDs, a converter is used, combined with the TP.VST59.PA671 main board, controlled by the SN510P PWM controller. As the power elements of the LED driver, keys of the type ME15M10-G 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 LD7530 microcircuits and power switches of the 60R900P TO-252 type.
MainBoard - the main board (motherboard) is a TP.VST59.PA671 module, using CPU chips: TSUMV59XE-Z1, SPI: FLASH W25Q32BV, AUDIO: YD1517P and others.
The R840 tuner provides TV reception and channel tuning.
FUSION FLTV-19C10 TV with an MT185WHB-N10 LCD, 18.5 "(47 cm) diagonal in 16: 9 format. The required screen brightness of 250 cd / m² is provided by LED backlighting. Dynamic contrast ratio of 50,000: 1 is achieved by special control of the LEDs The LED-panel of this TV is equipped with an end LED backlight - Edge LED. You can view high-quality images at a resolution of 1366x768 pixels in the standard of graphic decomposition 720p (HD Ready). The input high-frequency or video signal can be processed in analog .'S PAL, SECAM system, NTSC Image processing and the formation of a digital signal occurs in the standards 480i, 576i, 576p, 720p, 1080i, 2160p Supported multimedia file formats:. MP3, WMA, MPEG4, MKV, JPEG.
The power of the sound system 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. 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: 1360x768.
Attention! The MT185WHB-N10 panel of the FUSION FLTV-19C10 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.
