General repair guidelines for TV LCD LED
Repair of the FUSION FLTV-32C11 TV should begin with a careful external examination of all its components and modules. Sometimes, based on visible changes in the components of the device, it is possible to draw some conclusions and decide on the direction of further troubleshooting even before the necessary measurements are taken. Electrolytic capacitors of filters with a swollen body, as well as ring cracks or a layer of coal on burned-out resistors formed in soldered terminals of heating elements, sometimes tell the repairman the causes of the malfunction and possible consequences.
If the FLTV-32C11 TV does not turn on, does not make any sounds when it is turned on, and also no indicators on the front panel light or blink - there is a high probability of a malfunction in the power module. In some cases, there may be a malfunction only in standby power. In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is cut off, then it is necessary to check the diodes of the rectifier bridge and the key transistor of the converter for a breakdown of the PN junctions, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
If a breakdown of the power switch is detected, it should be remembered that in a switching power supply (IIP) it does not fail by itself for no reason that should be sought by checking other elements of the primary circuit - electrolytic capacitors, a PWM controller, which can only be checked replacement, as well as other semiconductor elements (diodes, transistors, zener diodes).
In cases where the FUSION FLTV-32C11 TV has lost an image, and the sound is there and all other functions are operational, there is a possibility of a malfunction of the LED driver (converter for powering the backlight LEDs of the LVW320CSOT panel). When you turn on the TV, the image may appear briefly and disappear immediately. It must be borne in mind that with such manifestations the LEDs themselves also fail.
Often in the absence of backlighting, disassembling the panel is required. It is necessary to check the serviceability of the transitions of the LEDs, as well as the reliability of contact connections in the rulers and connectors.
When trying to identify a break in the LED lines, it should be borne in mind that it is difficult to do this without disassembling the panel. For example, a current source is needed to open PN junctions connected in series.
When trying to repair the motherboard, you should first check the serviceability of linear stabilizers or power converters of microcircuits and, if necessary, update the software (software).
In some cases, it is necessary to check or replace (if necessary) the elements of the MB board (SSB) - CPU: MSD1306XSE-SB; SPI Flash: 25Q32FV; . In cases where the BGA processor is used, its malfunction is usually detected by local heating.
Remember! Attempts to self-repair by users of the FUSION FLTV-32C11 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

The required supply voltage for all nodes of the TV FUSION FLTV-32C11 provides a switching power supply.
MainBoard - the main board (motherboard) is a module TP.MS1306.PB772, using CPU chips: MSD1306XSE-SB; SPI Flash: 25Q32FV; and others.
FUSION FLTV-32C11 TV with LVW320CSOT LCD display, 32 "(81 cm) diagonal size in 16: 9 format. The required screen brightness of 300 cd / m² is provided by LED backlighting. Dynamic contrast ratio of 100,000: 1 is achieved by special control of the LEDs. The LED panels of this TV are equipped with edge LED backlighting - 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 analog systems PAL, SECAM, NTSC Graphic processing and digital signal generation occurs in the standards 480i, 480p, 576i, 576p, 720p, 1080i, 1080p. Supported media file formats: MP3, WMA, MPEG4, MKV, JPEG.
The power of the sound system 10 W (2x5 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), component, VGA, HDMI x2, USB. 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: 640x480, 800x600, 1024x768, 1360x768.
Overall dimensions: 834x503x122 mm.
Attention! The LVW320CSOT panel of the FUSION FLTV-32C11 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.
