PHILIPS Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILIPS | 42PFL3507D/78 | Inoperative standybay off | Replace the power supply part capacitor position c9353 replace with a 470mf 16v | C.M eletronica | |
| PHILIPS | 46PFL3008D/78 | It just stays on standby, | U702 | Replace u702 1.8v regulator | Gabriel GXP |
| PHILIPS | 40PFL3606D | Back light off, with sound and background image | Only the back light circuit stopped (inverting) | Measure all 22r resistors on the inverter, in my case the open resistors r438, r456 and r453 | Alex Lopes <small>This email address is being protected from spambots.

| PHILIPS | 40PFL5605 | Doesn't start | Change diode d907,911 I put sb5200 | cleber lima rs | |
| PHILIPS | 55PUG6801/78 | Does not turn on, completely inoperative, without +12v | Change without testing d9104 and u9109, remember that it works with a separate resistive bridge, it will show everything correctly, but it does not oscillate for feedback, take advantage and change all the electrolytics in the power supply! | HAHNRAHN | |
| PHILIPS | 32PFL3404 | Turns on normally for 2 minutes, the sound beeps, the image locks and turns off | 27,000 crystal near the processor box | Replace crystal | ELETRONICA RODRIGUES |
| PHILIPS | FWM593 | I'm sound | 1k resistor 343, on the sound output board, which powers u304 and u305, resistor is glued underneath the board | Marcelo | |
| PHILIPS | 20PT428 L01.2L | Does not pick up channels, does not tune | Era o diode 6001=bzx79-c33 e a r3427=12k match | Eletrônica Melo-Boa Viagem-Ceara | |
| PHILIPS | 55PFG7309/78 | Does not turn on, only standby LED is on | In addition to the entire capacitive chain of the 12v line being inflated, after the change was made the TV still did not turn on, the main one sent the ps-on command but did not arm the full 12v, the voltage remained the same as the standby voltage at around 8.5v , so I followed this line and saw that tsound was no vcc_on voltage (look at the service manual) | After analyzing the ps-on circuit, it was found that the q9332 was open! | Lucas |
| PHILIPS | 39PFL4707G/78 | Very white image | Cd42 smd on v-com short | samuel leite | |
| PHILIPS | AS425 Mú 207037 | Only lights up stand bay | But they have audio | Doesn't start. | Raimundo Rodrigues |
| PHILIPS | FWM575 | Inoperative does not turn on or stand by | Crystal on the processor side front plate | janilson JD ELETRONICA caetité | |
| PHILIPS | 42PFL3604 | In stand by, after some time in the socket it turns on normally | C474, c124 , c104 | Cinezio | |
| PHILIPS | 20PT3331 | It has a voltage of +b but it doesn't turn on. LED off. | R3445 no pino 8 do flyback de 1r | MARCONES DE ARARIPINA-PE | |
| PHILIPS | 20PT3331 | Doesn't start. LED off. | R3445 1r no pino 8 do flyback | Replace r3445 | MARCONES DE ARARIPINA-PE |
| PHILIPS | 39PFL4707/78 TPM9.2L LA | It doesn't turn on, it turns on when it wants to or when it turns on if you unplug it and turn it back on the TV doesn't work. | Check the 5v voltage at the power supply if ok... test the 3.3v voltage at the mb on the mosfeet (u701) if it is missing or altered the tv will not turn on. | Replace the transistor (u701) g1084-33 with another equal or better, see datasheet. | evando viana |
| PHILIPS | 40PFL3606D | The TV turned on, the screen kept turning off and on until it went into protection. | Problem with the belt/connector (flat) that connects the power supply board to the main board. | Re-soldering the connector and changing the belt will solve the problem. | PackageTrick |
| PHILIPS | 40PFL5606D/78 | General tips and observations about the power supply of this model | Tip 1: the TL431 of the 3v3 supply works with a reference voltage of 1.24v and not 2.5v as usual. tsoundfore it cannot be replaced by this other. tip 2: the ci driver lnk362pg is the same as the lnk362pn, in addition, the lnk364 can also be placed in its place as it performs the same function, it is just more powerful. | Gênios Eletronica SJ SC | |
| PHILIPS | 40PFL5606D/78 | 3v3 low power supply does not work, even after being fixed and revised. | Ci driver u101 ( lnk362) shorted, diodes d101, d102, d103 (all 1n4007) shorted. They were replaced and it still didn't wobble. | Zd103 diode (7.5v smd diode) with leakage. This diode goes close to the photo coupler pc101. Note: if you test it with a multimeter it will look good. You have to replace it directly as it only presents a defect in the circuit. | Gênios Eletronica SJ SC |
| PHILIPS | FW-C507 MINI HIFI SYSTEM | Direct driven tape deck | Ci drive located on faulty engine board | Replace the ci hef4094bt it controls the motor and the solenoids so if the driven motor and the solenoids are hot it is probably its fault check it and the drive transistors the ci 74hc4094 d may be compatible instead check compatibility in the datachit and replace |
