General recommendations for TV LCD LED repair
Possible malfunctions
- TV SONY KD-55XF9005 does not turn on and does not give any signs of turning on, does not respond to control buttons and to the remote control.
In some of these cases, the main switching power supply, the APS-419 module, is faulty. Its output voltages should be measured and, in their absence, the serviceability of the power switches (N-FET TO-220F) and rectifier diodes in the converters should be checked for possible breakdown.
In case of any breakdowns in the secondary circuits, the converter can operate in an emergency mode of a short circuit, and with a short circuit in the power elements of the primary circuit, the mains fuse or the current sensor at the source of the key is often cut off.
Mos-Fet keys used in switching power supplies usually fail due to a malfunction of other elements that can disable it in key mode, or provoke an excess of the maximum current or voltage values. These can be circuits supplying a PWM controller, damper or frequency setting circuits, or OOS (negative feedback) elements in the stabilization circuit. PWM controllers (PWM) PFC, PWM, in the absence of external damage and short circuit between the terminals, are checked by replacing them with a known good one.
- There is no image, the screen is black, there is sound, sometimes you can see barely noticeable outlines of the image in the ambient light of the screen.
In such cases, the most likely malfunction of the LED panel backlighting elements. Often the reason is a malfunction of the LEDs (open circuit, short circuit ...), or the connectors of the strips (strings) CCB 55 MBL-55030D915SN1, MBL-55030D915SN0, less often the LED driver turns out to be faulty.
To check the LED strips for breakage 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 indicator blinks or is on constantly, the TV does not turn on, does not respond to the remote control.
Repair or diagnostics of the motherboard 1-983-249-31 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). When repairing an MB board, it is necessary to check its components CPU, Scaler, eMMC, AUDIO, DC / DC. Defective elements must be replaced. If chips with BGA soldering technology are used, the problem in its implementation is detected by local heating of the chip.
In cases where there is no tuning for terrestrial or cable TV channels, you should make sure that the software is correct, as well as that the supply voltages on the CE553ZP tuner outputs match. It is also necessary to check with an oscilloscope the presence of pulses of data exchange between the tuner and the processor via the I2C bus.
Users and owners of TVs should remember that attempts to self-repair a SONY KD-55XF9005 TV without the appropriate qualifications and necessary experience can lead to serious negative consequences!

The main features of the SONY KD-55XF9005 device:
Installed matrix (LED panel) YD8S007DND01B or LSY550FF04-A01.
Matrix control uses Timing Controller (T-CON) 18Y_SHU11A2H2A4V0.0.
The LED driver 1-983-107-31 is used to power the backlight LEDs.
The formation of the necessary supply voltages for all nodes of the SONY KD-55XF9005 TV is carried out by the APS-419 power module, or its analogues using PFC, PWM microcircuits and power switches of the N-FET TO-220F type.
MainBoard - the main board (motherboard) is a 1-983-249-31 module using CPU, Scaler, eMMC, AUDIO, DC / DC and others.
Tuner CE553ZP provides reception of television programs and tuning to channels.
