TV PHILIPS	21PT9467C/78 SK 4.1L	I caught this TV turning on normally, but tsound was no image, only sound, it didn't light up the filament or generate high voltage. After almost setting it on fire. Analyzing the scheme I saw that tsound was d104 which on pin 34 of the ci when measuring I found that it was shorted.	D104 shorted		chinês eletônica solânea-PB
PHILIPS	PT112A	Vertical closed	R3400 (4k7) aberto		eletronica bianca ipira-ba
PHILIPS	29PT4631	It turned on and after a few minutes it turned off; Sometimes it would call with a few lines and hang up.	Era c2455 de 47/25 q7461 bc33725 e q 7463 bc32725.	And just replace these components and run to another TV.	DIEGO LIMA; NOVA TIMBOTEUA PA
PHILIPS	29PT4631/78R	Does not connect to 150v voltage from the normal primary power supply	L5561 27n open and c2561 100mf/160v with leakage	After replacement, it worked normally again	arnaldo j m p
PHILIPS	37PFL5603D/10 Q522. 2ELA	Image with too much brightness, you could see the images, but it looks more like a film negative	T-com board	To replace	luisrufo
PHILIPS	20GL1310	I closed the image and opened it, then, and when I had an image, the image distorted as if it were an AGC defect.	The bad contact that closed and opened the image was on the vertical top and the image distortion was the tda 8305 plus the capacitors, c162=22n, c182=22n disk and c130=6.8uf for 16v, with low capacity.	The vertical CI was resoldered, the three capacitors and the CI TDA8305 were replaced, it was tough but it was resolved...phew!	Armando de Olimpia Eletronica EvoluSom
PHILIPS	21PT5433/78R L03	One more tip for you guys, this TV would turn on normally, after a few minutes it would turn off and it would have a cushion effect and in AV it would turn off immediately	The cause was the open d6445 smd diode connected to the filament line.	Replace d 6445 smd.	This email address is being protected from spambots. You need JavaScript enabled to view it.
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.	Helio (ELETROSONIC)
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 MARCIORV	I'm sound, audio	Electrolytic capacitor 470 / 16v position 2444 near the frey back
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 tsound 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!!! sound 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
