PHILIPS 55PUT6400
General recommendations for TV LCD LED repair
Possible manifestations of malfunctions
- PHILIPS 55PUT6400 TV does not turn on and does not show any signs of turning on, does not respond to control buttons and to the remote control.
Most likely, in this case, the main switching power supply (SMPS) 715G6973-P01-002-002H is faulty. It is necessary to make sure that its output voltages are present and, if they are completely absent, check the power switches (TK18A60V, TK11A65D) and rectifier diodes for a possible short circuit.
In case of breakdowns in the secondary circuits of the converter, it can usually work in an emergency mode in a short circuit mode, and with a short circuit in the power elements of the primary circuit, the mains fuse or current sensor in the source of the key is most often cut off.
Mos-Fet power switches used in switching power supplies sometimes fail due to a malfunction of any other elements that can disable it in the key mode, or create an excess of the maximum permissible key parameters. These can be elements supplying a PWM regulator, frequency setting or damper circuits, or elements of negative feedback in the stabilization circuit. PWM controllers LD7591T, LD5532, in the absence of visible damage or outright short circuits between the terminals, are checked by replacing them with new ones, or known to be working properly.
- There is no picture, but there is sound, it reacts to the remote control. Or the image appears when turned on and disappears immediately
Often, in such cases, there is no backlighting of the LED panel. Often the cause of a malfunction is the lack of current in the LED circuit, for example, their open or short circuit, or a violation of the contact connections of the connectors.
When trying to detect a break in the LED lines, it should be borne in mind 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.
If PHILIPS 55PUT6400 has no picture, but there is sound, often the TPT550J1-QVN03 display backlight simply does not work. Moreover, in LED TVs, the LEDs inside the panel usually fail, less often the LED driver.
In such cases, you can see a barely noticeable image when the external light hits the screen.
Replacing the LEDs requires disassembling the TPT550J1-QVN03 LCD panel - a process that requires experience and qualifications from the master. We do not recommend doing such work on your own to owners of TVs and craftsmen who do not have experience in repairing LCD panels
If there is no image, and the backlight is on, the screen becomes slightly lighter when turned on, and in an open TV you can see light through the holes in the panel case.
In this case, the panel may also be faulty - damage to strips, loops, for example, as a result of moisture ingress after unsuccessful washing of the screen, the T-CON (Timing Controller) board may be faulty. But often the main board MainBoard 715G7030-M0G-000-005K turns out to be faulty, a software failure is also possible.
Then, first of all, you need to check the panel supply voltage, fuses on the T-CON board, as well as the supply and reference voltages of the column and line drivers - VGH, VGL, Vcom.
If these measurements are within the normal range, it is necessary to use an oscilloscope to trace the passage of LVDS signals from MainBoard 715G7030-M0G-000-005K, as well as synchronization signals to loops with drivers.
Flooded or unsuccessfully washed screens of LED TVs can be restored, in about half of the cases, usually if significant damage has not formed in the loops and panel strips.
- The TV does not turn on, does not respond to the remote control. The indicator blinks or signals the standby mode.
Repair or diagnostics of the 715G7030-M0G-000-005K motherboard should begin with checking the stabilizers and power converters required to power the microcircuits and matrix. If necessary, you should update or replace the software (software). Complex repair of MB (SSB) is possible only in a service center with the necessary equipment. Checking or replacing MT5593FPIJ, THGBMBG6D1KBAIL, H5TQ2G63FFR-RDC, TAS5760LD elements 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 the warm-up method.
Before changing the TDSY-G480D tuner, if it is not possible to tune to television channels, you should make sure that there are supply voltages, which must be measured at the corresponding tuner terminals and check the software for correctness. The pulses of data exchange between the tuner and the processor can be monitored with an oscilloscope.
Once again, we remind TV users: you should not try to repair yourself without the appropriate knowledge, experience and the necessary qualifications! Trust the repairs to professionals with sufficient experience in the field of electronic repair.

The main features of the PHILIPS 55PUT6400 device:
Installed matrix (LED panel) TPT550J1-QVN03.
Matrix control uses Timing Controller (T-CON) 55T22-C04.
To power the backlight LEDs, a converter combined with the main board 715G7030-M0G-000-005K is used and is controlled by the SSC9522S PWM controller. TK10A50D keys are used as power elements of the LED driver.
The formation of the necessary supply voltages for all nodes of the PHILIPS 55PUT6400 TV is carried out by the power module 715G6973-P01-002-002H, or its analogs using LD7591T, LD5532 microcircuits and power switches such as TK18A60V, TK11A65D.
MainBoard - the main board (motherboard) is a 715G7030-M0G-000-005K module, using MT5593FPIJ, THGBMBG6D1KBAIL, H5TQ2G63FFR-RDC, TAS5760LD and others.

Attention! The TPT550J1-QVN03 panel of the PHILIPS 55PUT6400 LED TV is an expensive and unreliable element.
Avoid any impacts on the glass and pressure on the screen surface to avoid damage to the LED panel!
It is also unsafe for liquid to spill onto the screen. Sometimes one drop is enough if it drips down the glass onto the cables to make the TV unrepairable.
