PHILIPS Repair Guide: Common Issues and Fixes

Brand	Model	Fault	Detailed Problem	Solution	By
PHILIPS	29PT4641 L04L AA	After 15 s, with image, it turns off. LED flashes 11 times, indicates beam current problem.	Lifting the r 3451, the TV is firm, but tsound is no brightness on the screen. After checking the circuit, the 680k smd resistor (3473) was less than 100k. I removed the 9488 jumper and replaced it with an 820k resistor.	Ready, just call, make the necessary adjustments, and run for the hug!	Luna
PHILIPS	20PT3331	The device turns on with the symptom of a weak tube, and with a small ripple on the screen, 2 seconds after turning off. primary power supplys with normal measurements.	Capacitor c2444 with low capacitance. generates a reduction in dc level, consequently drops the voltage that feeds the kinescope filament, it is advisable to change the resistors 3444 and 3443 as for this reason their values drop by more or less 2Ω		LOIMA SILVEIRA .sta. tereza RIO

PHILIPS	21PT5435	TV doesn't turn on	Horizontal output short, when I changed the horizontal output, the TV turned on with more ripple in the image as if it were a cap. duplicator	I fixed the processor and problem solved	eletronicaapolo
PHILIPS	FW C 270/19	After being replaced, the output kept turning off after a few minutes.	D 6555	Removed d6255 the micro system started to work normally	severino ramos
PHILIPS	28PW6515 A10	Sound sometimes doesn't work	Pin of the ic7064 intermittent internally, to avoid its replacement, disconnect this pin from the circuit. note: the function of the control's mute key stops working, it does not cut the sound		Oliva
PHILIPS	20PT324A	Turns on, after a few seconds it goes to stand by	Replace all transistors and diodes on the kinescope board	If possible, replace the board	eletronicaapolo
PHILIPS.	20 GL1346/78R	TV does not tune channels, same problem as the previous tip.	But the reason for this tip was r3956=10k, which was also open.	It was replaced and it was... ok.	Armando da Eletrônica só Tv.
PHILIPS.	20 GL1346/78R	TV does not tune channels.	R3958=18k aberta.	It was replaced and it was... ok.	Armando da Eletrônica só Tv.
PHILIPS	20 GL1346/78R	TV works when cold for up to half an hour, then it stops, the LED just keeps blinking	R3348=11k changed to 15k.	It was replaced and it was... ok.	Armando da Eletrônica só Tv.
