Make	Model	Symptom	Problem	Solution	By
PHILIPS	29PT4640 L01.1AL	In protection	Flyback and shorted oscillator transistor. bc32725		Eli
PHILIPS	29PT785A G88	Does not turn on, power supply inoperative	R3136 = 820k aberto, no pino 3 do ic 7140		BRUSKE
PHILIPS	20PT3331 L03.1L	Vertical closed at the top of the screen	C 2465 de 10uf por 160 volts	Replace with a 22μF for 160 volts	tony eletronica
PHILIPS	21PT5433	Appears character + Ñ has image	Check r 3442 of 100k opened or changed in the abl line		amsmariano
PHILIPS	14PT418A L01.2L	Turns on, then turns off, I found that the -13v power supply was missing, as a result of which there was no vertical deflection. I also verified that the 05 and 08v power supplys were missing in q 707 and 708. dz 6420 shorted out caused all this confusion.	Dz 6420 shorted.		Léo, Natal-RN
PHILIPS	42PF7321/78 PLASMA	Off and does not exit stand by mode	Sudden variation in AC input voltage	When disconnecting the 2 cables from the power supply to the ysus the sound returned. the ysus and the 2 upper and lower bμFfer boards were replaced. image returned to normal	Claudio Matulja
PHILIPS	29PT552A	Image with changes in horizontal frequency, small ripples,	Capacitor 2448 broken		Joacyr Sestrem
PHILIPS	FW-C555/19	The sound does not respond to control commands and some panel keys	Replace the 100p smd c-2613 and 2608 capacitors, they are located on the front panel next to the (rec) and (auto rev) keys.		Rudimar
PHILIPS	29PT5642	Screen closed vertically left	See ceramic capacitor 27j, code on the board - 9467		pardalzito
PHILIPS	20PT 3336/78R	When it turned on it was all green and with delay lines and after 5 seconds it turned off	Go to the tube socket and check the rgb voltages, everything was ok, I just resoldered the rgb socket and that was it, it was still turning off, I lowered the screen and that was it, there was a file		heliomar
PHILIPS	21PT5437/78 PT	Vertical closed,oscillating fly back(buzz at)	Open resistor 3445. replace and also replace cap.c 2446, as if it leaks it causes the resistor (fusistor) to burn out.		ELETRONICA ESTUDIER
PHILIPS	20PT3331	This TV would turn off after 5 seconds but it had normal sound and the image was a bit greenish	Broken kinescope socket		samuel3d
PHILIPS	14PT4131	It has a power supply, but it doesn't hoscilate	R 3425 open		Leônidas (Léo) Natal-RN
PHILIPS	29PT5642	TV doesn't turn on, power supply inoperative	Changing the photo coupler		Joacyr
PHILIPS	ANUBIS A ANUBIS A	This TV doesn't turn on, but it makes a noise at the power supply	I took measurements and the b+ has 5 volts. When removing the line transformer, the b+ had 98 volts.	I replaced the line transformer, and the TV was like new	mauviciu
RADIOLA- PHILIPS	GR1-AX GR1-AX	When I turned on the TV, the LED turned on and off, I couldn't hear the power supply, nor could the line transformer start. measuring voltages, there was only 310v on capacitor c2606 and 15v between resistors 3610 and 3613	As I suspected from the power supply, I measured the following components resistances 3616 3680 3614, diodes d6610 and 6613. They were all good.	Then, with the instructions given to me on the forum, I went to do another analysis and noticed that the 2527 capacitor in front of the transistor was cracked and that an electrolytic capacitor, the 2534, was a little swollen, I removed them and turned on the TV. The line transformer started to generate a noise like something was shorted, I suspected the transistor, when I measured it I saw that it was damaged, I replaced it (but I had already done it before) I installed some new capacitors.	mauviciu
PHILIPS	20PT324A	Volume worked, but the sound only sounded after number 37 on the volume indicator.	I changed the sound output, problem solved.		Leônidas (Léo)
PHILIPS	20PT123A	Inoperative, power supply in protection mode stand by led blinks faintly.	Capacitor 2447 next to the horizontal output transistor short circuited, be careful when this capacitor is short circuited, do not turn on the television without a horizontal load as this may cause damage to the yoke (deflector)	Replace the capacitor and observe the 1k 3454 resistor in parallel with the yoke (deflector)	WAGGUINHO
PHILIPS	29PT552A	Inoperative, power supply completely stopped, no voltage at the outputs.	Capacitor c2550 (331x1kv) short circuited.	Replace the defective component and the device returned to normal operation. If the device keeps turning off in faster times, replace the diode in parallel with the one mentioned and replace the capacitor with one of 471x2kv as this improves the diode's dissipation.	WAGGUINHO
PHILIPS	L6.1 14PT1353 L6.1	Stand by LED lights up, does not start	Diode 6420, also check vertical 7401, 7402		spda
