General repair guidelines for TV LCD LED
Possible malfunctions
- The PHILIPS 23PHH4109 TV does not turn on at all. There is no reaction to the remote control and control buttons from the front panel. Indicator lights do not light or flash.
With such manifestations, the 715G6297-P01-001-001E power module usually fails. It is necessary to measure its secondary output voltages, and if they are absent, check the power switches (TK6A65D) and rectifier diodes in the converters for a short circuit.
In case of any breakdown of semiconductors in the secondary circuits, the converter can usually work normally in emergency short circuit mode. There are no output voltages. And with a short circuit in the power elements of the primary circuit, as a rule, the mains fuse breaks and less often the current sensor at the source of the key.
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. PF6200 PWM controllers, in the absence of visible damage or explicit short-circuit between the terminals, are checked by replacing with new ones, or obviously working.
- 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.
As a rule, in such cases there is no display 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 TV does not turn on, does not respond to the remote control. The indicator blinks or signals standby mode.
Repair or diagnostics of the 715G6092-M01-000-004K motherboard should begin by checking the stabilizers and power converters needed to power the microcircuits and matrix. If necessary, update or replace the software (software). Often, the MB (SSB) card must be replaced in case of complex malfunctions that are difficult to detect. When trying to repair, you should check its elements - MT5580PUEI, 24C128, NC / TC58NVG2S3ETAI0, THGBMAG5A1JBAIR, TAS5760LD and replace failed chips with new ones. Some malfunctions may be due to the use of BGA soldering technologies in modern Main Board technologies. Typically, such defects are detected by local heating of the chip.
Before changing the ST03CS-2-E tuner, if it is not possible to tune to television channels, make sure that there are supply voltages, which must be measured at the corresponding tuner terminals and checked for correctness. The pulses of the data exchange of the tuner with the processor can be controlled by an oscilloscope
Once again, remind users! Attempts at self-repair of the PHILIPS 23PHH4109 TV without the appropriate qualifications and necessary experience can lead to its complete non-repairability!

The appearance of the power supply
Main features of the PHILIPS 23PHH4109 device:
Installed matrix (LED-panel) LTA230AN01.
To power the backlight LEDs, a converter is used, combined with a power supply, controlled by the PF7001S PWM controller. As the power elements of the LED driver, keys of the MTD55N10Q8 type are used.
The necessary supply voltages for all nodes of the PHILIPS 23PHH4109 television are generated by the 715G6297-P01-001-001E power module, or its analogs using PF6200 microcircuits and TK6A65D type power switches.
MainBoard - the main board (motherboard) is a module 715G6092-M01-000-004K, using chips MT5580PUEI, 24C128, NC / TC58NVG2S3ETAI0, THGBMAG5A1JBAIR, TAS5760LD and others.
The ST03CS-2-E tuner provides television reception and channel tuning.
