General repair guidelines for TV LCD LED
Possible malfunctions
- The FUSION FLTV-32B110T TV does not turn on, does not respond to the remote control and the control panel buttons, does not light up or blink indicators.
In this case, first of all, you should check the operability of the main power source - AC / DC network voltage converter, all of whose elements are located on the MainBoard TP.MS3663S.PB818 board. It is necessary to measure its output supply voltages, and in case of their absence, check the serviceability of the power switches (TO-252) of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
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.
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, 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 sometimes be in the power of the LEDs, but more often in their malfunction (breakdown or break), sometimes in the violation of the contact connections of the LED strips.
To check the health in the LED circuit, it is better to use a current source with a maximum voltage of 200V. We do not recommend using any voltage sources for this purpose. You can test each LED individually with a simple Chinese multimeter (powered by 9 volts) in the P-N-junction test mode. If you connect the red probe of the multimeter to the anode of the LED, and the black to its cathode, then the 3-volt LED will light up slightly, and in the opposite direction you can detect the transition of the emergency zener diode. A zener diode PN transition is indirectly indicative of a LED-a
- The indicator on the front panel blinks, the TV does not turn on in the operating mode, it 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). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - CPU: MSD3663LSA-SW, SPI Flash 25Q64 and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
Before replacing the DT-9NT372-RF01 tuner, if there is no tuning for the channels, first check the software and the supply voltage at its terminals. It is also necessary to make sure that the tuner and processor can exchange data via the I2C bus
Once again, we remind TV users: you should not make attempts to repair it yourself without the appropriate knowledge, experience and the necessary qualifications! Entrust repair to professionals with sufficient experience in the field of repair of electronic equipment.
FIRMWARE FOR SPI FLASH -----------> FUSION FLTV-32B110T V1T09, Main: TP.MS3663S.PB818, Panel: PT320AT01-1
The appearance of MainBoard TP.MS3663S.PB818 is shown in the figure below:TP.MS3663S.PB818
Main features of the FUSION FLTV-32B110T device:
The matrix (LED panel) PT320AT01-1 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 DT-9NT372-RF01 provides the reception of television programs and tuning to channels.
FUSION FLTV-32B110 TV with a PT320AT01-1 LCD display, diagonal size 31.5 "(80 cm) in 16: 9 format. The required screen brightness of 220 cd / m² is provided by LED backlighting. Dynamic contrast ratio of 100,000: 1 is achieved by special control of the LEDs In the technology for making 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 of graphic decomposition 720p (HD Ready) Supported media file formats: MP3, MPEG4, DivX, MKV, JPEG.
The power of the sound system 16 W (2x8 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, VGA, HDMI x2, USB x2. An output for connecting headphones is provided.
Attention! The panel of the PT320AT01-1 LED-TV FUSION FLTV-32B110 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.
