PHILIPS	14GX1618/78R ANUBIS - VA	TV doesn't turn on	Led on, only on standby, hcc voltage at 1.95v	Transistor 7423 is good, but when I replaced it, the TV turned on again	odivaldo araujo
PHILIPS	29PT4635	The vertical heats up and burns	The vertical one was broken, I changed it and there was a c25v 47uf dry capacitor, I changed it		This email address is being protected from spambots. You need JavaScript enabled to view it.
PHILIPS	20PT529	Doesn't start	7522 supply smd transistor		aedo
PHILIPS	21GX1669/78R GR6-AL	Dark screen with sound when opening it writes, it lightens very little, no characters appear	Replace eprom		Schulz
PHILIPS	20GL1041		Low power supply	Replace transistor ts355	Moraes sptv
PHILIPS	20PT529A/78R ****	Low sound at maximum volume.	Capacitor c-2883	Replace directly without testing.	wagner
PHILIPS	DIVERSOS T/GL VáRIOS	Retrace lines and dark cloud-like screen at the bottom of the screen.	Clean the glue between the vertical capacitors and the chassis. They are to the left of the flyback or tsh.		Conscerta
PHILIPS	29PT4635	With retrace lines and then turns off	Ci code. 7330 is the tda 6107jf	I found that it had a voltage of +- 200v, even so there were traces on the screen, just replace it!	caio
PHILIPS	21PT5433	Vertical closed at the top	Capacitor c2460 82kx100v alterado		retec
PHILIPS	20PT122A	LED blinks weakly	Low power supply	Dry electrolytic capacitor 47/160 c2551	ECeletronica
PHILIPS	PV461	The functions on the screen (channel number) kept disappearing, sometimes nothing appeared or disappeared prematurely.	S1802	I replaced the internal capacitor of the s1802. It was perfect.	moura1
PHILIPS	21PT6456/78 L03-1LAA	After suffering a change in the electrical network which blew the varistor 3505 and the fuse, it only turned on at 110v	After changing the fuse and varistor, it was necessary to change the tea1506t (7520) to work on 220v.	110909	MAIRES
PHILIPS	29PT4631/78R	No plot and no sound	This TV had no plot and no sound. When activating the remote control, the LED responded normally. in the on position there was 126v at the tsh collector. It seemed like that classic defect of this model in which you just need to replace the transistors q7461 (bc337-25) and q7463 (bc327-25) plus the capacitor 2455 (47μfx25v). I was able to observe that only the bc337 was altered, but after replacing the three components the defect did not change. in the collector of q7461 it had 11v base 0v and emitter 0.3v. I started to suspect that the q7462 (pdtc143zt) could be the cause of there being no voltage at the base of the q7461, but as it is an SMD that is difficult to buy anywhere, I did some more tests and the defect was the q7460 (bu4508dx) completely shorted between base and emitter. Before, I had only tested between collector and emitter (where the short normally occurs). As I had a bu2725dx available I put it as a replacement. in place of q7461 I put 2sd667 and in place of q7463 I put 2sb647. An interesting detail is that the q7461 heats up much more than the q7463, which is why I put a small heatsink on it.
PHILIPS	20CN4465	Message on display f1	Capacity 100mf in CR receiver shield	To replace	alexander
PHILIPS	14PT4131/78R	Dead	Photo-coupler 7515 tcet 1103 defective		Jaison
PHILIPS	PT4640/78 L1	Turns on/off in a few seconds	C2455,q746/q7463 e screen	Replace these components even if they are good, and lastly, if they continue to turn off by themselves, check the flay screm" due to internal oxidation causing this problem, if possible, when adjusting, mark the position and add a drop of glue so that it does not become loose	ELETRÔNICA PALAURO
PHILIPS	29PT5645	Turns on, TV with dark screen vertical lines and disarms	Shorted smd diode 6451 and capacitor 2465 10/100v		ladmyr rezende
PHILIPS	20GX	Blurry image	Change the kinescope socket		edson proesi
