Philco Repair Guide: Common Issues and Fixes

Brand	Model	Fault	Detailed Problem	Solution	By
PHILCO	PCM2051	Blinking led	+b ok I measured the +b of the T702 transformer and it was having too much consumption it should have been +or- 35v it only had 8v I noticed the fly back with heating, I changed it and it was ok	Replace flyback ov2094/d1 obs these flyback giving you a lot of defects as it had already been replaced days ago (I had 3 identical cases with this blessed fb and it wasn't cheap)	fernandocamarques
PHILCO	TPF 2902AV	TV with black bands on the horizontal sides	C 706 as low capacitance	Also replace c708	multsom
PHILCO	PCS2952	Dark screen with a red line running horizontally and a colored circle appeared in the center of the screen every 2 seconds and a blinking LED.	33v from the varicap is ok 20v from the power supply is ok 12v from the power supply is ok IC701-9v regulator that is connected to the 12v line of the fly back is oscillating between 3 and 4.5v and at its input the voltage oscillates between 11 and 6 v . 200v in the video is 134v. as the 9v voltage of the ic 701 was oscillating both at the output and at the input, I connected an external regulator to test, so the TV worked normally, the trick I did was connect a PC power supply using the 12v output on a new 9v regulator, I then concluded that there must be a problem with the rectification of the 12v that feeds this ci (ic701), so I started changing c722 - 470uf/16v and the TV started working again.

PHILCO	TP-2052N	Turning off the 220v network, and the 110v network works normally	Cap.smd c912	Replace with a conventional 4n7 100v ceramic	edson
PHILCO	TP-2054		The device is turned on, it oscillates, the filament lights up, and in approximately 4 or 6 seconds it turns off, the LED blinks a few times. r-910 and r-912, check again, d-909, replace them, it's ok.

PHILCO	PCS2976	Sizzling and popping sound.	Capacitor was replaced (c450) - 2.2 x 100v	Replace	amigobastos
PHILCO	TP29C21	With 3 lines on the screen red, green and blue and after a few seconds it turns off	Black image with 3 lines	Shorted diode d601 vertically you can put in4007 that works	lelobq
PHILCO HITACHI	PC1427U	TV works normally but makes a very annoying noise, sounding like a “cricket buzzing”	There are many factors that lead to this defect. In some cases it could even be the flyback. But oddly enough, after changing some capacitors on the power supply and on the horizontal circuit, which seemed suspicious, I noticed that the noise was coming from the t901 (power supply transformer )not finding another one to replace it, I just removed the core (mineral charcoal in the shape of an m) and the noise disappeared.		eletrônica novaera(luiz frota)piracuruca-PI
