General repair guidelines for TV LCD LED
Possible malfunctions
- The AIWA 22LE3110 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.
In such cases, the KPS-L036C1-01 power supply is usually faulty. Then we recommend that you measure its output voltages and, if they are absent, you should check the health of the power switches and rectifier diodes of the converters for a probable short circuit.
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.
Breakdown of power switches (MosFet) in pulsed sources is sometimes caused by malfunctions of other circuit elements, for example, in circuits supplying a PWM controller, frequency-setting or damper ones, as well as in negative feedback (OOS) stabilization circuits. PWM controllers (PWMs) FSQ0465R, if they do not have visible damage to the case and open short circuit between the terminals, are usually checked by replacement.
- There is no image, but there is sound and reaction to commands from the remote control. Or the image appears immediately after turning on and disappears.
In most of these cases, a malfunction is detected in the nodes and backlight elements of the LED panel. The reason for this may be a break in the LED circuit, or a problem in stabilizing their power supply.
To check the LED lines for breaks without disassembling the panel, for example, a current source will help. It is impossible to open series-connected PN junctions with a simple multimeter, a voltage of the order of several tens of volts is required.
- 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 T.MS6M181.13B 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 board (SSB), you need to check the health of its elements - CPU: MST6E181VS-LF-Z1, SPI FLASH: GD25Q32. Defective components should be replaced.
Before replacing the AFT7 / W130G tuner, if there is no tuning for the channels, 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 to users! Self-repair of the TV AIWA 22LE3110 without the appropriate qualifications and the necessary experience can lead to its complete non-repairability!

Key Features of AIWA 22LE3110:
Installed matrix (LED panel) HT215F01-100.
The matrix control uses the Timing Controller (T-CON) HT215F01-100.
The LED driver KLD-L013E04-01 is used to power the backlight LEDs, it is controlled by the OZ9998AGN PWM controller. As power elements of the LED driver, keys of the type ME15N10-G are used.
The necessary supply voltages for all nodes of the TV AIWA 22LE3110 are generated by the KPS-L036C1-01 power module, or its analogs using FSQ0465R microcircuits.
MainBoard - the main board (motherboard) is a T.MS6M181.13B module, using CPU chips: MST6E181VS-LF-Z1, SPI FLASH: GD25Q32 and others.
The AFT7 / W130G tuner provides TV reception and channel tuning.

Attention! The HT215F01-100 panel of the AIWA 22LE3110 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.
