General repair guidelines for TV LCD LED
Possible malfunctions
- The FUSION FLTV-32B100 TV does not turn on and does not show any signs of operability at all. There is no reaction to the remote control and control buttons from the front panel.
In such cases, the common power source is often faulty - an AC / DC voltage converter, which is combined with the elements of the main board TP.V56.PB816. It is then necessary to measure its output voltages and, if they are absent, you should check the power switches (70R600 TO-252) and the rectifier diodes of the converters for a short circuit probability.
In case of breakdowns of semiconductors in the secondary circuits, the converter can usually work abnormally in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse often breaks.
The breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damping, as well as in negative feedback (OOS) stabilization circuits. PWM controllers (PWM) PWM SOT23-6, if they do not have visible damage to the case and open short circuit between the terminals, are usually checked by replacement.
- 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.
As a rule, in such cases there is no display backlight. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
- The TV does not enter the operating mode, does not respond to the remote control. The indicator on the front panel lights up constantly or blinks.
Repair or diagnostics of the TP.V56.PB816 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: TSUMV56RUU-Z1, SPI Flash: 25Q32CSIG. BGA chip malfunctions are usually easy to detect by warming up.
TV users and owners need to remember that attempts to repair the FUSION FLTV-32B100 TV independently without the appropriate qualifications and necessary experience can lead to serious negative consequences!

Main features of the FUSION FLTV-32B100 device:
The matrix (LED panel) 32H8- (A) is installed.
To power the backlight LEDs, a converter is used, combined with the main board TP.V56.PB816.
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 power switches of the MMD70R600P TO-252 type.
MainBoard - the main board (motherboard) is a TP.V56.PB816 module, using CPU chips: TSUMV56RUU-Z1, SPI Flash: 25Q32CSIG and others.
FUSION FLTV-32B100T TV with 32H8- (A) LCD, 32 "(81 cm) diagonal size of 16: 9 format. The required screen brightness of 220 cd / m² is provided by LED backlight LED. Dynamic contrast ratio of 100000: 1 is achieved by special control LEDs work. Direct LED backlighting with rear LEDs is realized on the LCD panel of the TV - Direct LED. You can view HD images at a resolution of 1366x768 pixels in the standard 720p graphic decomposition (HD Ready). Supported media file formats: MP3, WMA, 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, audio x2, component, VGA, HDMI x2, USB x2. 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: with stand 728x470x183 mm, without stand 728x440x86 mm.
TV Weight: with stand: 3.8 kg, without stand: 2.06 kg.
Attention! The panel 32H8- (A) of the FUSION FLTV-32B100T 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.
