Make	Model	Symptom	Problem	Solution	By
PHILIPS	32PFL3403/78	Turns on then turns off on stand by	Transistor q900 smd 4403 changed	In this case, the Q900 TV transistor was replaced and it worked perfectly.	carlos df
PHILIPS	32PFL3404	Lamps light up dimly and go out with low voltage on df1 90v the correct 240v	Defective component was the cf1 221k/1.5kv connected in parallel cf1 and df1		Erons
PHILIPS	40PFL6605D/78 LC9.3L	TV turns on normally, with audio but no image. backlight lights up normally.	Ci position 7kfe on the main pci damaged. That's why the display lacks 15v power supply.	Replace of ci fds9435a position 7kfe.	rafaelmoraes99
PHILIPS	42PFL3507D/78 M9.1 L LA	The stand by light does not come on!	Voltage in the primary power supply of 5.2v with 1.65v when connected to the signal board, when disconnected it returns to normal.	Just changing the c9353 on the 330µf x 16v power supply board, I put 470µf x 16v and run for the hug!	Robusto59
PHILIPS	HTD5520X/78	Inoperative. no standby...grilling	Zd507 changed	Zd507 can be replaced with a 33k/2w resistor	jr_TEC
PHILIPS	21PT5433	Vertical closed at the bottom	Change c2446	C2446 voltage 470x16v	jcgiantomaso
PHILIPS	29SX8879	When the image is dark, you hear hissing in the flyback, with scratches on the image, like a high voltage leak	4.7uf capacitor (2902) and 39k resistor (3901) open.	Replacing the capacitor and resistor.	Lucianomachado
PHILIPS	21PT5433/78R	Black stripe at the top and 3 colored lines	I replaced the 2465 10uf/160v capacitor in the bd135 collector, it solved the problem right away	This TV would go to waste, but it was resurrected, hugs	wagner poltronieri
PHILIPS	21PT5433 L03.1L	Turns on and the voltage is 125v, if you want to lower it a little to around 115v, place a resistor on the collector base of the q7451.	It had a 10k resistor and the voltage was 109 to 110v and the horizontal was a little closed.	I tested several values until reaching 115v with the 55k resistor, good luck.	Eronaldo (erontec)
PHILIPS	21PT5433 L03.1L	Turns on image with inverted cup effect and sometimes turns off.	Defect in the vertical coil deflector is 14 homs and horizontal 4 homs and it was measuring 8 homs.	Check output of the adjustable coil on top of the coil in my case it was broken, I tied it up I did some welding and Pumbaa measured 4 homs and the TV was normal.	Eronaldo (erontec)
PHILIPS	FW-C777	No sound on the outputs, only on the headphones.	R 3325 of 33k open.	Philips fw-c777 sound with audio in the headphones, but without the outputs. I followed all the tips on the internet and nothing happened. the voltages, transistors, stk412 030 output, everything ok. The "letters" in the diagram correspond to the connection of the large ci to the circuit. to unlock the protection, in my case, I placed a 1000mf63v electrolytic on pin 16 letter p of the output ci, this one with the positive ground, because on this pin 16, it measured negative 51 volts and the stk generated audio in the boxes... this without much power. Then I looked at the resistors from this stage that fed pin 16. I found the 33k r3325 open. I replaced it and removed the electrolytic that will be added to unlock the STK and the sound returned to normal, with full power, in my case it was the open resistor.	Giovani pires bitencourt
PHILIPS	43PFG5000/78	No image, normal backlight	C702 shorted on tcon board		garrom
PHILIPS	21PT5435	TV turns on and then turns off in a few seconds, when it stays on, black stripe at the top and bottom of the picture tube	Capacitors: 2465 (10uf, 160v) and 2446 (470uf, 16v)	Capacitors with low capacitance, replace with capacitors of equal values	Donizete Alves de Sousa
PHILIPS	26PFL5322/78	White negative image	White image	Replacement. ci-as04f. a hug	estevao de Jesus ventura
PHILIPS	29PT5642	Does not generate a high, the power supply comes on and then resets and the LED flashes	I changed the photo coupler, disconnecting the flyback, changing some electronics and nothing, I removed the horizontal output, it was fine but on a high scale tsound was a small leak, I replaced it and the TV worked perfectly.	Changing the horizontal output without testing is valid for all Philips TVs.	Bardock Eletrônica
PHILIPS	32PFL4007D/78	The stand by light does not turn on and does not accept commands from the remote control, it only turns on with the power button	Software failure since in the measurements I noticed the receiver was acting	Software update
PHILIPS	42PFL3403	I'm sound	D6402 that takes power to the 8v regulator that powers the ci 7411 (back of the board)		HP ELETRONICA
PHILIPS	29PT9467	Turns on and in a few seconds turns off	When you turn on the main key it arms the relay and goes into sby, keep pressing the channel keys without stopping so it doesn't turn off easily (most of the time it's the tube itself), speed up the screen on the flyback, if it hits the retrace lines the cushion effect, the defect may be in the horizontal width cap.	In my case it was the c438 cap of 2n7 ps. Always replace the 2 b+ caps on these TVs, thanks.	SYSTEM ELETRONICA
PHILIPS	32PFL3403	TV completely inoperative	Jumper j14 match.	The cause of the j14 break was the 33μF/450 c910 with an electrolytic leak, which is why it is necessary to replace it even if it shows good on the capacimeter.	marco.32
PHILIPS	32PFL3403	TV won't turn on completely inoperative	Jumper j14 match.	Check bd2 if it is shorted, it is close to j14 and check r3. in my case I only replaced j14 which was broken.	marco.32
