General recommendations for repairing TV LCD
Possible malfunctions
- BBK LT2610S TV does not turn on, does not respond to the remote control and control panel buttons, indicators do not light up and do not blink.
In some of these cases, a fault is detected in the 569HU1320D power module. In the absence of the necessary supply voltages in the secondary circuits of the converters, it is necessary to check the power switches and rectifier diodes for a possible partial or complete breakdown.
In case of any breakdowns in the secondary circuits, the converter can operate in emergency short circuit mode, and during short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key more often 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 controllers STRNW6856, STR-A6159M, FAN7529, 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
The defect can be caused by problems in the nodes or elements of the backlight of the display, or in the power supply of the lamps or the inverter.After checking all the electrolytic capacitors of the filters that are involved in the power supply of the inverter, you must ring in its converter power keys for breakdown and secondary windings of transformers for an open.
If in diagnosing a malfunction, it is necessary to disable the inverter protection, there is a risk of failure of the power elements of the inverter, and special care is required during work, and after they are finished, it is necessary to restore the protection circuits for further safe operation of the TV by the owner in normal mode.
- 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 569HU5601C 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). In cases of attempts to repair the MB (SSB) board, it is necessary to check the serviceability of its elements - 24C32AN, A25L40, TDA4470 which may require replacement with new ones. If a BGA processor is installed, there is a possibility of a violation of the soldering of the contacts of its conclusions with the board (it is diagnosed by heating).
Before replacing the TDQ-6FT / W124XC tuner, if there is no channel tuning, you must 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
Attention TV owners! Attempts at self-repair of BBK LT2610S are not recommended by the manufacturer and can lead to serious negative consequences!

The appearance of the power supply
Main features of the BBK LT2610S device:
Installed matrix (LCD panel) V2601B1-L02.
The matrix control uses the Timing Controller (T-CON) B6539E2-DR ;.
To power the backlight, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the BBK LT2610S TV are generated by the 569HU1320D power supply module or its analogs using the STRNW6856, STR-A6159M, FAN7529 microcircuits.
MainBoard - the main board (motherboard) is a 569HU5601C module, using 24C32AN, A25L40, TDA4470 and others.
The TDQ-6FT / W124XC tuner provides TV reception and channel tuning.
BBK LT2610S LCD TV with V2601B1-L02 LCD, 26 "(66 cm) diagonal size in 16: 9 format. 500 cd / m² screen brightness is provided by CCFL (EEFL) fluorescent lamps. Maximum brightness to minimum ratio (contrast) ) is 800: 1. 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 standard max 480i, 480p, 576i, 576p, 720p, 1080i.
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 x3, component, SCART, RGB, VGA, HDMI. 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.
