Dear community, I have a Daewoo Lcd DLX-19L1 TV which has a fault, does not turn on, Standy's blue LED is flashing. I disarmed the equipment and focused on the source and got 6 swollen capacitors, all in the cold stage of the source, 3 of 680mfx25v, 1 of 1000mfx16v, 2 of 470mfx25v. I changed the mentioned components for new ones, however, the problem persists, does not turn on the TV. A tick, tick, tick, tick, tick, undefined tick is heard, then I checked the mosfet transistor NEK K3115, the PEC. 816 SB10100CT, rectifier diodes, resistors, fuses, heat resistance and all ok. I have basic knowledge of electronics, so I proceeded to measure output voltages from the source to the main board and compare them with what is specified on the card (source): Pin ------ 1 and 2 = 5.0 V ----------------- Voltage 2.7 to 3.7 and unstable. Pin ------ 5 and 6 = 8.5 V ----------------- Voltage 4.5 to 4.8 and unstable. Pin ------ 9 and 10 = 14.3 V -------------- Voltage 4.5 to 5.1 and unstable. Subsequently, I measured the PEC transistor on a card (source). 816 SB10100CT and I could see that it enters short, causing the sound tic, tic, tic, tic, tic, indefinite tic. Then, I disconnected the coil L204 from the circuit and the irregular sound disappeared, I measured voltage again and the values are as follows: Pin ------ 1 and 2 = 5.0 V ----------------- Stable 5.0 V voltage. Pin ------ 5 and 6 = 8.5 V ----------------- Stable 8.5 V voltage. Pin ------ 9 and 10 = 14.3 V -------------- Voltage 14.3 V stable. Mind you, the coil will take it out of the circuit to check its operation and if it finds ok Then, I proceeded to connect the source to the main board and turn on the equipment, now the TV is activated, it emits more sound however it does not give image. Check the output of the inverter and there is no voltage that supplies the lamps. The Opto-coupler replaced it with another one with similar characteristics and still the problem remains. Annex images describing the location of each component. Please any help you can give me I will be grateful, thanks

Dear friend, I was able to change the 6-pin Mosfet AO4606 and the voltages are already stable and even the sound tic, tic, tic, tic, tic, tic indefinite was eliminated. Now, the lamps are still not activated, how did you solve this problem or what should I measure?
