General repair guidelines for TV LCD LED
Possible malfunctions
- PHILIPS 24PHH4109 does not turn on and does not show any signs of performance at all. Does not blink indicators and does not respond to control buttons.
Most often, with such manifestations, the main power module 715G6297-P01-000-001H is found to be faulty. It is necessary to measure its output supply voltages, and in case of their absence, check the serviceability of the power switches (K6A65) of the converters and rectifier diodes for the probability of breakdown in PN semiconductor junctions.
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, in the absence of visible damage or frank short-circuit between the terminals, are checked by replacing with new, or obviously working.
- 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.
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 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 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 715G6092-M01-000-004X motherboard should be started by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). Complex repair of MB (SSB) is possible only in the conditions of a service center with the necessary equipment. Checking or replacing components TC58NVG0S3ETA10 requires the necessary training and professional skills in repairing modules at the component level. Problems associated with the use of BGA soldering technologies can sometimes be diagnosed by warming up.
If you suspect a malfunction of the ST03CS-2-E tuner, first of all, you need to verify the correctness of the software, as well as the presence of the necessary levels of supply voltage and data exchange pulses with the processor via the I2C bus at the corresponding terminals of the tuner.
Owners of the 24PHH4109 TV are recommended for repairs to contact only qualified specialists with the necessary work experience! Self-repair attempts without the appropriate knowledge and skills can lead to irreversible negative consequences!

Main features of the PHILIPS 24PHH4109 device:
Installed matrix (LED-panel) TPM236H3.
To power the backlight LEDs, a converter is used, combined with a power supply.
The necessary supply voltages for all nodes of the PHILIPS 24PHH4109 television are generated by the 715G6297-P01-000-001H power supply module, or its analogs using power switches of the K6A65 type.
MainBoard - the main board (motherboard) is a 715G6092-M01-000-004X module, using TC58NVG0S3ETA10 chips and others.
The ST03CS-2-E tuner provides television reception and channel tuning.
