General repair guidelines for TV LCD LED
Possible malfunctions
- FUSION FLTV-32H110T does not turn on, does not respond to buttons and remote control, indicators on the front panel do not light up and do not blink.
First of all, in such cases, you should verify the operability of the common switching power supply (IIP) - AC / DC voltage converter of the mains voltage. All source elements in this TV model are located on the MainBoard TP.MS3663S.PB818 main board. In the absence of the necessary supply voltages in the secondary circuits of the converters, it is necessary to check the power switches (TO-252) and rectifier diodes for a possible partial or complete breakdown.
In case of breakdowns of the diodes in the secondary circuits, the converter can operate in emergency short circuit mode without output voltages, and during short circuit in the power elements of the primary circuit, the mains fuse and / or current sensor at the source of the key usually 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, but there is sound, it reacts to the remote control. Or the image appears when you turn it on and immediately disappears
Usually in such cases there is no backlight LED-panel (matrix). The reason can be found in the malfunction of the LEDs, in the violation of the contact connections of the LED strips, or in the provision of their power (LED-driver).
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.MS3663S.PB818 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). Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing CPU elements: MSD3663LSA-SW, SPI Flash 25Q64 requires the necessary training and professional skills to repair modules at the component level. Problems associated with the use of BGA soldering technologies can sometimes be diagnosed 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 tuner CDT-9NT372-RF01. 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 TV owners! Attempts to self-repair FUSION FLTV-32H110T are not recommended by the manufacturer and can lead to serious negative consequences!
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-32H110T V1T09, Main: TP.MS3663S.PB818, Panel: HK315LEDM-JH65H
The appearance of MainBoard TP.MS3663S.PB818 is shown in the figure below:TP.MS3663S.PB818
Main features of the FUSION FLTV-32H110T device:
The matrix (LED panel) HK315LEDM-JH65H is installed.
To power the backlight LEDs, a converter is used, combined with the main board TP.MS3663S.PB818, controlled by an 8 pin 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-252 type power switches.
MainBoard - the main board (motherboard) is a module TP.MS3663S.PB818, using CPU chips: MSD3663LSA-SW, SPI Flash 25Q64 and others.
The tuner CDT-9NT372-RF01 provides the reception of television programs and tuning to channels.
FUSION FLTV-32H110T TV with LSC320AN09-H02 LCD display, 32 "(81 cm) diagonal size in 16: 9 format. The required screen brightness of 200 cd / m² is provided by LED backlighting. Dynamic contrast ratio of 100000: 1 is achieved by special control of LEDs In the technology of manufacturing the screen of this TV model, LED backlighting is implemented, high-quality HD images can be viewed at a resolution of 1366x768 pixels in the standard for graphic decomposition 720p (HD Ready) 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.
The external interface (communication with other devices) is supported by standard input and output connectors: antenna input (RF), AV, audio x2, component, VGA, HDMI x3, 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.
Attention! The LSC320AN09-H02 panel of the FUSION FLTV-32H110T 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.
