Make	Model	Symptom	Problem	Solution	By
PHILIPS	29PT4635 L01.1L AC2K3	Does not turn on, the LED sometimes lights up, the voltage at the base of 7461 and 7463 was 0.11v and at the emitter it was 0.37v, the other voltages were all normal.	Solution: transistor 7406 bu4508dx -> horizontal output *note: the low voltages made me change the transistors 7461, 7463 and the capacitor 2455 but after changing them the voltages remained low, so I concluded that this was due to a short in the secondary of the transformer 5461 this is because of the transistor 7460 -> horizontal output which was burnt and causing a small leak between collector and base and as its base is connected to the secondary of the 5461 this caused a short in it which was reflected in the primary and killed the voltages of 7461 and 7463.

PHILIPS	14GX1619	Inoperative power supply does not arm	Crimping the horizontal output and with very high tension on the altered fly back pacifier	Replace o fly back	eletroclaudio aguas belas pe
PHILIPS	14GX1619	White screen with colored retrace lines on the front side and no video	Defective vertical outlet	Replace the same	eletroclaudio aguas belas pe
PHILIPS	21PT5435	It has sound, no image and no characters. I measured the screen voltage it was zero. I came to the conclusion that the tube was shorted, I removed the socket and the deflector and tapped around the kinescope tube and the short disappeared. I put the deflector and socket in place. the screen tension arrived and the image appeared normally.	Kinescope with shorted grids, consuming screen voltage.		VALDO RECIFE
PHILIPS	20PT4331/78R	Turns off on tuned channels, in AV it works normally	R3449 open	Replace of the same	paulo
PHILIPS	20PT3331 L0	Customer said that he had gotten water through the antenna; well the power supply was a little low, I cleaned it in the photo attached to the power supply, it started to turn on but it turned off in 3 seconds then it was really bad, the defect was just the scrin joint and it was very low and it turned off then It just increased, it was ok 88178817 francisco mutirao	Increase the scrin potentiometer as much as possible, everything is ok, good luck	Let's help everyone because it's great when you find a tip from a friend who gives a big hug to professional friends	marcos melo cascavel ceara
PHILIPS	20GX 1659	Disarming	After checking everything - stand bi power supply I noticed that when it was turned off the vertical stretched, I replaced it but the defect continued	Solution I replaced the two electrolytic caps, it worked great - no more disarming hug	jose santos vicente
PHILIPS	21PT8467/78	Dark screen, normal sound with characters and when entering the error code it shows error "10"	R3442 open	Replace the 100k 1/4w resistor with a 1/8w one	ELETROSONIC (GARANHUNS)
