PHILIPS	29PT5642 L04	Vertical closes at the bottom and then turns off.	Check voltage on t7605, 5v collector.	Replace of r 3606 56k replaced for more	joaomvjr
PHILIPS	20PT528A	Turns on and has video and audio and turns off	Fb tweak		eletronica bianca ipira-ba
PHILIPS	21PT424A-524A-324A L9-SS	No secondary power supplys - smelled burning	1k c2550 with leak or toast	Replace, use a 2kv one	jasvan souza
PHILIPS	14PT414A/78	Doesn't start. inoperative.	Primary power supply ok. The defect was the open resistor (r3525) of 33Ω at the gate of the switching transistor.		Gilcimar Rocha Pereira
PHILIPS	FWM 143	Inoperative, does not turn on or display.	X301	Replace x301 32,768 mainboard tubular	joaomvjr
PHILIPS	29PT458A/78	When turned on, normal image and sound comes on and then turns off	After having done everything and not solving the problem I found the cause of the defect, an open 10k resistor in position 3204 connected to the RGB connector that comes from the main board to the tube board	Replace the 10k resistor in position 3204 and good luck	PATRICK
PHILIPS	FW-C505	Burned out sound outputs (an 7591)	As it is missing on the market, it can be replaced by the an 17850, just one modification, connect a 2k2 resistor between pin 1 and 2 of the ci.		pardalzito
PHILIPS/MAGNAVOX	14MT2131/78	Dark screen with no sound but with characters	Faulty memory	Replace a eepron 24c16wp	samuel leite
PHILIPS	32PFL3403	Dead	Resistor 1r, position on the power supply board, r-929, replace it, it's ok.		Cláudio Ribeiro, TECNOSAT ELETRÔNICA E INFORMÁTICA, Jataí-Go, This email address is being protected from spambots. You need JavaScript enabled to view it.
PHILIPS	21PT6433/78	When turned on, it displays a reddish image and turns off	When resoldering the kinescope board components, the TV worked for a while and then showed the same defect again.	Changing the red output transistors on the kinescope board 7308 bf422, 7313 bf422 and 7314 bf423, perhaps only one of them was defective, but as I tested and they showed no difference between them and no leaks, I decided to replace them all straight away.

PHILIPS	HTS3011/55	Does not turn on inoperative, does not have normal power supply voltages.	5bk power capacitor c933 without capacitance	Replace with a new 220μF x 16v capacitor	celinvds
PHILIPS	20PT3331	No audio	Electrolytic capacitor 470 / 16v position 2444 near the frey back		MARCIORV
PHILIPS	29SX8879 G8	Inoperative (protection circuit acting) tick...tick...tick...	When opened, the l5945 ferrite was found fallen, probably the cause of the burning of d6904 (by228) which was shorted. When it was replaced, the TV turned on but l5980 started to smoke and it was found that the reason was that q7980 (bd440) was also shorted. After being replaced, the TV showed excess width because there was no 12v in its collector. Even though the L5980 was shorted for a short time, it is damaged and is the cause of the problem. As it is an offline TV, I managed to replace the L5980 with another one taken from a Philips GL1340 (S516) just by adapting a bridge between two terminals. Note: during the tests q7981 (bc547) also shorted out. Searching the internet I found the following tip on how to recover l580... good morning friend!!! here is the solution to your problem: the width defect is caused by the burnout of the 5980 coil. Unwind and wind it with 31awg wire measuring approximately 14.30 meters. Once this is done, the voltages (12v) appear and the trimpt adjustments start working again, ok!!b		littlecarlos
PHILIPS	14PT316 A	The a/v doesn't work.	Zener diode 6.8 v, position 6116, shorted.	Replace it, it will be ok!	Cláudio Ribeiro, TECNOSAT ELETRÔNICA E INFORMÁTICA, Jataí-Go, This email address is being protected from spambots. You need JavaScript enabled to view it.
PHILIPS	14GL1310	After a while on, the image disappears, it appears out of tune, it falls horizontally, the image is distorted and black and white	05

PHILIPS	21PT6456	There is no voltage in rf and av	Memory		tonico
PHILIPS	GR1 GR1AL	Retrace lines on top	Normally it is the c410 of 100mf, but in this case it was the open r410 of 680r.	Check, and if you are going to replace it.	jasvan souza
