PHILIPS Repair Guide: Common Issues and Fixes

Brand	Model	Fault	Detailed Problem	Solution	By
PHILIPS	20PT-428/78R	Inoperative + b ok	In my case it was r.3543 /82k		Zezinho
PHILIPS	20GL1049	Screen without video with lines of retractions	C2410 no vertical	Replace	ELETROCLAUDIO AGUAS BELAS
PHILIPS	21PT9467/78 SK4.0L CA	Inoperative, LED goes out when activating power and lights up shortly afterwards	Philips TV 21pt9467/78, LED on, when the power key is pressed the LED goes off, but immediately returns to stand by. During the period in which the circuit is activated tsound is approximately 250v of screen voltage and only 5.8v in the +13v and -13v circuits that supply the vertical. defect ic301 (tda4865aj) shorted. in the schematic it appears as tda4863aj. One detail... when turning on this device without the vertical cide, the sound appears normally and also the bright line in the center of the screen as it appeared on old TVs.		liittlecarlos
PHILIPS	20PT3331 20PT3331	Device turns off 5 seconds after switching on.	Excess current in the vertical output, especially if the expand key is pressed.	After checking all the hoods, I mean capacitors and other possible shit like these pts, I had to put a 3 oms/5 watt resistor on the +b line and the bd 135 collector. Everything ok. stay with god.	djalma_ This email address is being protected from spambots. You need JavaScript enabled to view it.
PHILIPS	20PT4331	I'm sound	Low sound, sometimes disappears.	Replace c2444 470mf/16v	LOU
PHILIPS	20PT3331	The device turns on, after about 8 to 10 seconds it turns off.	R-3443 and r-3444, both 1r, in parallel, kinescope filament supply	Replace it, it's ok.

TV PHILIPS	20PT529A/78	Does not arm the + power supply that goes to flyback	R3543 abert		domingos josé
PHILIPS	29PT4635/78	Jagged image then turns off	Capacitor c2445		altair santos
PHILIPS	29PT4643	Image with white lines, even adjusting the screen didn't work	I don't know which capacitor it was, but I replaced all 3 and it's new.	C2418,2413 e 2412	This email address is being protected from spambots. You need JavaScript enabled to view it.
PHILIPS	FWM922/BK	Turns on the sound and after 5 seconds + or - it turns off and goes to eco power	See the smd 7506 transistor wsound the collector must have 0 volts, in this case the transistor was shorted to the collector base	Replace 7506	Ademar
PHILIPS	HTS3011/55	When you increase the volume, it turns off and returns to standby	Alternating current control resistance of 0.22r was 0.60r	R940 0, I agree	Eletro Center
PHILIPS	21PT9467C	Shrinks the image horizontally (like a cup) forcing the board open, re-soldering doesn't solve everything.	Manufacturing defect: the resistor r314 was not completely inserted into the hole in the board and is only touching the solder, which appears to be perfect.	I don't even need to tell you what to do.	Ronie Grein
PHILIPS	26PFL3403D/10 TCM2.0E	Network led comes on and then goes out (you hear the relay switch on)	Power supply 5 turns off	Replaces ic1- viper22a (note see jc -chante )	Corvo
PHILIPS	20PT3143	Colorless black and white	Unprogrammed eeprom memory	Open the service menu put 000 in the first option of the op or reprogram the memory
PHILIPS	29GX1898	Works with noise in the power supply driver transformer and image with ripple	D 6519 shorted		Master Eletronica
PHILIPS	20PT260S L7	Horizontal tv closing from left to right and turning off	Frame closing and turning off	Bad capacitor c2469 replace without testing	jtm
PHILIPS	21PT8467/78 L03.1L	Alloy with buzzing sounding internal short in the tube, vertical closed with a little open band.	R3445 from 1r open.		ED'SOM & VIDEO
PHILIPS	20PT529A	Turning off by itself	Screen low	Regular screen	EletroletroClaudio PE
PHILIPS	21PT5432	It turns on a red screen and then turns off	Voltage increase on pin 56 of tda 9570h/n1/ai1012	Dear colleagues, this TV has this symptom when turned on, it works, the screen is completely red with lines of retraces and then it turns off, checking the RGB line I found a voltage of 8v coming out of pin 56 of the TDA 9570h/n1/ai1012, as others on pins 57 and 58 were normal as indicated in the scheme, to check if this voltage was actually coming out of the tda, I raised the resistors 3201, 3202, 3203, both 100r, and this increase in voltage on pin 56 was confirmed, thus confirming the Defect in the TDA and with its replacement the TV started working normally again, I hope it can help some colleagues.
