General repair guidelines for TV LCD LED
Possible malfunctions
- The DIGITAL DLE-2610 TV does not turn on and does not show any signs of operability at all. There is no reaction to either the remote control or the front panel control buttons.
With such manifestations, a malfunction is most likely to be detected in the power module. It is necessary to measure its secondary output voltages, and in case of their absence, check the serviceability of the power switches of the converters and rectifier diodes for a short circuit.
In case of breakdowns in the secondary circuits, the converter can operate in a short circuit mode, and during short circuit in the elements of the primary circuit, the main fuse usually breaks.
The breakdown of Mos-Fet keys used in pulsed sources is often caused by malfunctions of other elements, for example, power supply, frequency-setting, damper ... as well as elements of the Negative Stabilization Feedback. The PWM chip FAN7602C can also cause a malfunction of the power switch of the converter and is checked by replacement.
- There is no image, but there is sound and reaction to the remote control. Or for a second, the image may appear immediately after switching on.
Usually in such cases, a malfunction is detected in the backlight nodes of the LED panel. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
It is impossible to check the line of series-connected LEDs without a special current source, and for this purpose it is not safe to use any voltage sources above 12V for them. Then it remains only to open the panel and check each LED separately. Usually, Chinese 9V-powered multimeters light up a single 3-volt LED, if you connect the probes in the forward direction, the red probe to the anode, and the black to the cathode. In dual 6-volt LEDs, the PN junction of its emergency zener diode can serve as an indicator of health. In the event of a LED malfunction, its zener diode will either be cut off or broken into short-circuit.
- The indicator on the front panel blinks, the TV does not turn on in operating mode, it does not respond to the remote control.
Repair or diagnostics of the T.MS6M182.81B 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). If it is not possible to replace the MB (SSB) card, you need to check the health of its elements - MST6M182VS-LF-Z1, NT5TU32M16DG-AC, 5Q32BVS1G, IT6633E-P, TPA3110D2,. Defective components should be replaced.
AFT7 / W130G tuner malfunction is established after checking the software and all supply voltages at its terminals. The data exchange of the tuner with the processor via the I2C bus can be controlled by an oscilloscope.
It should be remembered! Attempts to independently repair the DIGITAL DLE-2610 TV, in the absence of the necessary qualifications and experience, are categorically not recommended and are fraught with negative consequences, up to the complete non-repairability of the device!

T.MS6M182.81B can be used in TVs:
DIGITAL DLE-2610 (Panel V260CD1B23-2), FUSION FLTV-32H17 (Panel LC320WXE (SB)(V2)), SUPRA STV-LC3244WL (Panel LTA320AN01), SUPRA STV-LC3244WLD (Panel LTA320AN01 ), SUPRA STV-LC3219W (Panel LC320WXE), SUPRA STV-LC32S650WL (Panel MT3151A03-1 VER22), SUPRA STV-LC46S990FL (Panel TC460FPE5).
Main features of the DIGITAL DLE-2610 device:
The matrix (LED panel) V260CD1B23-2 is installed.
The matrix control uses the Timing Controller (T-CON) V260B2-XC03.
A converter controlled by the BD9261FP PWM controller is used to power the backlight LEDs.
The necessary supply voltage for all nodes of the DIGITAL DLE-2610 TV is provided by a switching power supply using FAN7602C microcircuits.
MainBoard - the main board (motherboard) is a module T.MS6M182.81B, using microchips MST6M182VS-LF-Z1, NT5TU32M16DG-AC, 5Q32BVS1G, IT6633E-P, TPA3110D2, and others.
The AFT7 / W130G tuner provides TV reception and channel tuning.
