General repair guidelines for TV LCD LED
Possible manifestations of defects
- Haier LE32M600 TV does not turn on. There are no signs of operability. The indicators on the front panel do not shine and do not blink, and the remote control and control buttons do not respond.
Often in such cases, the power supply from the mains voltage, the elements of which are located on the MainBoard MSTV2409-ZC01-01 main board, is faulty. It is necessary to measure the secondary output voltage of the AC / DC converter, and in case of their absence, check the serviceability of power switches 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 mains fuse usually 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. It can be supply, damper circuits, or elements of OOS (negative feedback) stabilization. The reason for the breakdown of the power switch may be PWM (PWM). It is checked only by replacement with a known good one.
- There is no image, there is sound, it is responding to the remote control. Or immediately after turning on for a second, the image may appear and immediately disappear.
The most likely in these cases is a malfunction of the LED backlight. The reason can be both in the power supply of the LEDs, in their serviceability (breakdown or breakage), as well as in the violation of the contact connections of the LED strips.
To detect a break in the LED lines without disassembling the panel, a current source is required. It is impossible to open transitions connected in series with a simple multimeter; voltage of several tens of volts is necessary.
- The indicator blinks or lights constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the MSTV2409-ZC01-01 motherboard should begin by checking the stabilizers and power converters needed to power the microcircuit 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: TSUMV59XUS, SPI Flash: MX25L3206E, PT2308-S. BGA chip malfunctions are usually easy to detect by warming up.
We recommend LE32M600 TV owners for repair only to qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!
To reduce the backlight current in LED drivers with the AP3039AM controller and the AP3608EM terminal stage (AP3039AM-G1 & AP3608EM-G1), the AP3608EM (AP3608E) microcircuit should proportionally increase the resistor from terminal 14 (ISET) to the housing. The maximum current in each channel (in milliamperes) for the Rset resistor (in kilo-ohms) is determined from the ratio 1.194V / Rset. In channels connected in parallel, the currents add up.

Key Features of HAIER LE32M600:
Installed matrix (LED panel) LK315T3HB94 or ST3151A05-5.
The matrix control uses the Timing Controller (T-CON) MT3151A05-3-XC-1.
To power the backlight LEDs, a converter is used, combined with the main board MSTV2409-ZC01-01, controlled by the AP3039AM-G1, AP3608EM PWM controller. As the power elements of the LED driver, keys of the MDD1951 type are used.
The power module is combined with the MainBoard and is made according to the flyback AC / DC voltage converter circuit.
MainBoard - the main board (motherboard) is an MSTV2409-ZC01-01 module, using CPU chips: TSUMV59XUS, SPI Flash: MX25L3206E, PT2308-S and others.
