Make	Model	Symptom	Problem	Solution	By
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.

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
PHILIPS	FW-C507 MINI HIFI SYSTEM	Radio doesn't work	Ci drive of function panel leds radio cd etc defective	In this defect, note that the LEDs did not light up and no function replaces the IC and resolves the IC in question and the one located at the end of the board on the right side 74hc4094d by changing it and the radio just chirps again and does not tune in, replace the other one on the left side of the ci mentioned above and the same ci are two identical ones, they control the LEDs on the entire device and also the operation of the radio
PHILIPS	40PFL3606 40PFL3605	Voltages fluctuating on the ci 7j00 and the TV has no image.	Position 3j22 resistor open and position resistor 3j26 open replace both.		PLAY BACK
PHILIPS	20PT3331	Turns on and off in seconds	Replace the 10k resistor r3475 next to the vertical deflector coil connector		dj pituka
PHILIPS	FWM779	On and off or on and off	Transistor of the 7506 overvoltage detector with leakage on the regulator board		Stiltec
PHILIPS	42PFL3604	Turns off stand by and tsound is no power on or bl on signal	After changing the capacitors c474, close to the crystal, c168, c106, c99, c806, the TV continued with the same symptom, turning it on, turning off standby and not arming the power supply. press channel-and channel+ at the same time.	Even so, the TV continued to turn off. Some light bulbs also needed to be replaced.	Mitzko eletronica
