Make	Model	Symptom	Problem	Solution	By
PHILCO	PH24M LED A2	Doesn't start. Not even the LED lights up.	Power supply with low and pulsing 12v line, between 11.2v and 11.4v.	Solved solve	Eletrônica R-Tec
PHILCO	PTV32D12D	No image.	Connector on the back light is faulty.	I removed the rb840 inverter resistor (4r7). the measurements were 61.7v and 248ma and then it was 59.1v and 178ma. I made the replace to avoid return.	Eletrônica R-Tec
PHILCO	PTV43E60SN SERIE B	Does not turn on back light	Ci u81	Replace ci u81	central audio e video
PHILCO	PH24M LED A2	Doesn't start. Not even the LED lights up. totally dead.	Power supply. IC1 (LD7531A SMD). little regulator with 6 legs. I didn't find it new in my city. So, I scrapped it.		Eletrônica R-Tec
PHILCO	24M	I'm sound	Capacitor de 1000x10volts e1500x25vol		João Marques
PHILCO	PH32E32	After a while it was turned on, the backlight turned off.	R98, 680k, with low resistance. power supply board near the LED drive		Stiltec
PHILCO	PTV49F68DSWN	Connect to the network, turn on stanby, press power, the TV turns on but no image, the backlight does not turn on, tsound is no time to measure the backlight voltage at the power supply.	When disconnecting the wire that goes to the "adj" position of the power supply (pin that comes from the main board) and shorting this adj to the "pson" the TV releases the backlight but still no image.	This model is the same as Sony TVs, when tsound is a short in the tcon and/or display, the processor blocks operation and acts as protection. the defect was in the tcon, those 10μF smd capacitors in position c427/428/429	MIGUELTV
PHILCO	PH49U21DSGW JUC7.820.00167500	TV turns on the sound of the channel and image in the background, but the blacklith does not turn on	Short in backlight circuit	Replace ub1 (mp4010) db1, db2 (sk320u) db3 (15v zener) qb1 (mdd14n25) rb9, rb8, rb7 and rb6 (0.33r0.33r0.33r and 0.51r all resistors in parallel)	Felipe Francisco (Gov. Valadares)
PHILCO	PH14	TV stopped, won't turn on after a while.	Shorted capacitor, on the 5v line. c217 of 470uf/16v close to the microprocessor.	After changing the TV ok.	George Pontes
PHILCO	PB126	Radio keeps changing the frequency alone	Replace q1 s8550
PHILCO	PH28D27D LED	Turns on the logo appears and turns off.	Defective LED bars! LED burned out or shorted	This TV uses 3 bars in parallel with 5 6v LEDs on each bar, so each bar only supports 30v. in my case the power supply was sending 32.5v! 1st replace the LEDs or bars. 2nd lower the voltage on the LEDs to 29.2v by removing the 2r2 smd resistors (rb13, rb14) good luck.	EvandoViana
PHILCO	40L2400	Turns off after about 30 minutes.	Voltage regulator n803 (1117-1.5v) which is next to the processor, dropping voltage on the in pin. As it heats up, the voltage drops and heats up the resistors r831 and r832 (both 15r/2w).	I turned off the LED chain to prevent it from returning.	Eletrônica R-Tec
PHILCO	PH21SS	Turning on and off repeatedly, with vertical closed	I replaced the c549, problem solved, I turned it on and it worked perfectly		GBSAT ELETRÔNICA
PHILCO	PH21M SS	TV turns on with 3 colored lines at the top of the screen	Vertical filter capacitors	Replace them all	ASSISTEC
PHILCO	PH21M SS	The TV arrived without turning it on, just with the LED on, when I pressed the power key it turned off the LED and turned it on again but it didn't turn on	The cause of the defect was the shorted vertical ci tda-78141	After changing the ci the TV works again	ASSISTEC
PHILCO	PH21C	Turns on and off, works, the image appears and turns off	Replace r315 10k, see also, r316 5k6 next to vertical discipient and c317, r274		DJ PITUKA
PHILCO	PH21C	Does not turn on, nor does the stand by LED light up, power supply defect	Replace transistor q801 2sc1815		DJ PITUKA
PHILCO	PH21US A1	Turning off	Transistor v502 e capacitor c580		3R
PHILCO	PH21M2 SS PH08K-C01	Horizontal bar, image folded horizontally	Zd483 (9.1v)		RICHARDO SILVA
PHILCO	PH24D20DM2 SW10	Turns on but no image	Q813 on main board open	Replace him	barbadinha
