General repair guidelines for TV LCD LED
Possible malfunctions
- The FUSION FLTV-24B100 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.
The malfunction in such cases should be sought in the elements of the power source - the mains voltage converter (AC / DC), which is located on the MainBoard TP.V56.PA671 main board. It is then necessary to measure its output voltages and, if they are absent, you should check the power switches (TO-252) and the rectifier diodes of the converters for a short circuit probability.
In case of breakdowns in the secondary circuits, the converter, as a rule, can emergency work in the short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse 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 and all other functions work. Sometimes when you turn on the image for a second appears and disappears.
A malfunction is usually most likely in these cases at the backlight nodes of the display 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).
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.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the TP.V56.PA671 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). When repairing an MB board, you need to check its CPU components: TSUMV56RUU, EEPROM: PN25F32. Defective items should be replaced. If chips with BGA soldering technology are used, a problem in its implementation is detected by local heating of the chip.
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-24B100 V1S11, Main: TP.V56.PA671, Panel: HV236WHB-N41
The appearance of MainBoard TP.V56.PA671 is shown in the figure below:TP.V56.PA671
Main features of the FUSION FLTV-24B100 device:
The matrix (LED panel) HV236WHB-N41 is installed.
To power the backlight LEDs, a converter is used, combined with the main board TP.V56.PA671, controlled by an 8pin 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 scheme of a flyback AC / DC voltage converter using PWM SOT23-6 microcircuits and TO-252 type power switches.
MainBoard - the main board (motherboard) is a TP.V56.PA671 module, using CPU chips: TSUMV56RUU, EEPROM: PN25F32 and others.
FUSION FLTV-24B100T TV with HV236WHB-N41 LCD, 23.6 "(60 cm) diagonal size of 16: 9 format. The required screen brightness of 200 cd / m² is provided by LED backlighting. Dynamic contrast ratio of 80000: 1 is achieved by special control of the LEDs Direct LED backlighting with direct LEDs is realized on the LCD TV panel. HD images can be viewed in high resolution at 1366x768 pixels in the standard 720p graphic decomposition (HD Ready). Supported media file formats: MP3, MPEG4, MKV, JPEG .
The power of the acoustic system of sound 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, HDMI, 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.
The power consumed by the TV working in the network mode is 45 watts.
Overall dimensions: with stand 552x370x165 mm, without stand 552x335x70 mm.
TV Weight: with stand: 2.65 kg, without stand: 2.1 kg.
Attention! The HV236WHB-N41 panel of the FUSION FLTV-24B100T 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.
