General repair guidelines for TV LCD LED
TV PHILIPS 40PFL8008S / 60, like many other electronic devices, it is advisable to start repairing by inspecting all external and internal elements. Often, by the external signs and nature of the damage to the elements, it becomes possible to draw some conclusions and determine a further algorithm for finding a defect before making the necessary measurements at control points. If charred resistors, swollen electrolytic or cermet capacitors, ring cracks in the soldered terminals of transformers or heating elements are detected, it is advisable to establish the causes and consequences of the malfunction that has arisen, as well as to check the connected elements and assemblies.
In cases where the PHILIPS 40PFL8008S TV does not turn on, does not respond to the remote control and buttons, no indicators on the front panel light up or blink, and there are no sounds and no signs of operability when turning on, the power supply module FSP163-4FS02 2722 171 is most likely to be faulty 90779 or there is no processor power on the motherboard (a typical defect of some PHILIPS TVs). In the general case, first of all, it is necessary to check the electrolytic capacitors of the secondary rectifier filters and the fuse at the input of the network. If it is broken, then you should check for breakdown of the PN junctions of the rectifier bridge diodes and the key transistor of the converter, which can either be on a separate radiator or integrated with a PWM controller in a common chip. Possible options.
As a rule, the keys in switching power supplies (SMPS) are reliable enough and rarely fail for no reason to be looked for by checking other components of the circuit - electrolytic capacitors, resistors and semiconductor elements of the primary circuit. The PWM chip is verified by replacing it with a known good one.
If the PHILIPS 40PFL8008S does not have an image, there is sound and the channels are switched, there is a possibility of a malfunction in the backlight LED circuit of the LTA400HL18 002 panel, or their power converter - LED driver. Sometimes when you turn on the image appears and disappears immediately. In such cases, it is necessary to check the electrolytic capacitors of the power filter of the LED driver itself, including in the secondary rectifier of the main PSU.
To check the health of the LEDs and contact connections in their power circuit, the panel must be disassembled.
When trying to detect a break in the LED lines, it should be taken into account 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 the motherboard YU 312.6 AI1 is faulty, first of all it is necessary to check all the linear stabilizers or power converters of its chips, and also, if necessary, update the software. Sometimes you can check the health of MB only by replacement.
Before changing the SUT-RE214AN tuner, if it is not possible to tune to television channels, make sure that there are supply voltages, including varicap power (30-33V), which must be measured on the corresponding tuner pins.
Attention to the owners! Attempts at self-repair of the PHILIPS 40PFL8008S TV are not recommended by the manufacturer and can lead to serious negative consequences!

The appearance of MainBoard 310431366185 is shown in the figure below:
310431366185
The weak point in the PHILIPS TV models assembled on the QFU1.2E LA chassis is the main board SSB (MainBoard), which usually refuses to work after two years of operation. Replacement required.
The cost of the board is quite high, which sometimes raises the question of the feasibility of repairs.
Despite the efforts of designers to complicate or exclude the possibility of repairing the board, there are still options for its restoration.
Attention to the masters !!! You should pay attention to the drop of compound from the bottom of the board. When trying to heat the board or reball of BGA chips, the compound must be completely removed. Otherwise, the paths will be closed, which will significantly complicate the further repair of the board.
