General repair guidelines for TV LCD LED
Possible malfunctions
- The HAIER LE32F1000T TV does not turn on and does not show any signs of turning on, it does not respond to the control buttons or the remote control.
First of all, in such cases, you should verify the operability of the common switching power supply (IIP) - AC / DC voltage converter of the mains voltage. All source elements in this TV model are located on the MainBoard TP.MS3463S.PB801 main board. In the absence of the necessary supply voltages in the secondary circuits of the converters, it is necessary to check the power switches (TO-220) 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 keys used in switching power supplies usually fail due to a malfunction of other elements that can put it out of operation in key mode or provoke an excess of the maximum current or voltage. These can be circuits supplying the PWM controller, damping or frequency-setting circuits, or elements of OOS (negative feedback) in the stabilization circuit. PWM controllers (PWM) PWM SOT23-6, in the absence of external damage and short circuit between the terminals, are checked by replacing with obviously good ones.
- 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.
Usually in such cases there is no backlight LED-panel (matrix). Usually the cause of the malfunction is in the breakage of the LEDs, or in the connectors of the LED strips, but sometimes the LED driver also turns out to be faulty.
When trying to detect a break in the LED lines, it should be taken into account 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, the indicator indicates standby or operating mode, or blinks.
Repair or diagnostics of the TP.MS3463S.PB801 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). Sometimes they require checking or replacing (if necessary) the elements of the MainBoard - CPU: MSD3463GU, SPI Flash: 25Q64B, AUDIO: OB6220VP. In cases where the BGA processor is used, its malfunction is usually detected by the local heating method.
If you suspect a malfunction of the XF-3SDT-H tuner, first of all, it is necessary to verify the correctness of the software, as well as the presence of the necessary voltage levels and pulses of data exchange with the processor via the I2C bus at the corresponding terminals of the tuner.
It should be remembered! Attempts to self-repair a HAIER LE32F1000T 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-serviceability of the device!

Key Features of HAIER LE32F1000T:
Installed matrix (LED-panel) HV320WHB-N80 CN320CN7201.
The matrix control uses the Timing Controller (T-CON) 32HD.
To power the backlight LEDs, a converter is used, combined with the TP.MS3463S.PB801 main board, controlled by the SN51DP PWM controller. As power elements of the LED driver, keys of the AOD458 type are used.
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 TO-220 type power switches.
MainBoard - the main board (motherboard) is a TP.MS3463S.PB801 module, using CPU chips: MSD3463GU, SPI Flash: 25Q64B, AUDIO: OB6220VP and others.

Attention! The HV320WHB-N80 CN320CN7201 panel of the HAIER LE32F1000T 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.
