Make	Model	Symptom	Problem	Solution	By
PHILCO	PH32U20DG	Doesn't start	The TV wouldn't turn on, it just kept making a noise at the power supply, ticking, ticking... I noticed that the 12v power supply was oscillating and when I put a load on it it stabilized. That's when I suspected that the defect was in the primary and I found the cp205 22uf x 50v capacitor to be defective.		Alex lima
PHILCO	PTV32E21	Usb dando 10v	Responsible circuit u1p4 (mp1653), faulty fb circuit, usually the responsible 1kΩ smd resistor r4p15, or r4p13 51kΩ, also test r4p14 33k, in my case it was only r4p15 1k		lucian oliveira 61991271532 DIGITAL TECH
PHILCO	CPH06M	When turning on the power key, it blinks once	Check c704, 708 and 712.		Matias ERP
PHILCO	B481	Low sound	Check/replace all electrolytic capacitors		Matias ERP
PHILCO	B481	I'm sound	Check swap d205 and d206		Matias ERP
SOM PHILCO	PB500BT	The device makes a humming sound, a constant noise without sound coming out.	We just need to change the 5-vot regulator, ok, the dc 7805 only has one on the board.		Galileu Rocha
PHILCO	PH42M61	Stopped, but with normal secondary power, neither the stand by LED lights up.	Replace circuits n801 and n802 reference fr9889 and that's it.		Alberi F S
PHILCO	PH32B51DSGWA	Inopernate nem led stand by acende	Ci nw901 ld7536r no primary from ruim power supply	Replace nw901 ld7536r	NEI
PHILCO	PH32E20DSGWA	Lights up stand by but doesn't turn on	Resolved with an update that was carried out with the black light turned off but you could see the process in the background, after finishing the stand by LED went off and the TV turned on normally		eletronicatual mondubin
PHILCO	PH58E51DSGW	LED bus current reduction.	To reduce the current voltage of the LED bus on the inverter board with the ci hai 7203ha. Currently this CI does not have a datasheet. remove the 20kΩ resistance from each ci on its pin 12 and place a 30kΩ one or associate it in series with a 27kΩ resistor plus 2k7.Ω, totaling 29k7Ω or 27,700Ω r102 r202 r302 the original value of each resistor is 20kΩ. the original working current is 1,166 amps. With the change, the bus will work with a current of 0.866 amps, leading to a reduction of 25.75%, guaranteeing a longer useful life of the bus.		aldin
PHILCO	PH39N91DSGWA LED	Faulty LED backlight	After replacing the backlight LEDs with new ones, perform the following replacement:	Remove rw821 (1.5Ω) from the circuit and only leave rw819 and rw820	leitemarcellus
PHILCO	PH40UDSG LED	No image LEDs on black screen	Shorted capacitor (cd7) on the display board	Replace with the same value!	Luis Claudio
PHILCO	PH58E51DSGW	After a while it's on, it just keeps turning off	Main transformer of the power supply with one of the pins charred	Repair the traffic	PATRICK ELETRÔNICA
PHILCO	PTV32E20D	Does not leave stand bay	Change the 4 aluminum type capacitors and run to dim dim in my case ok good luck		eletronica publisom
PHILCO	PTV50G70SB	It doesn't turn on, nor does the STBY LED light up.	After checking, I found c55 shorted.	C55 replace, next sound output.	arock
PHILCO	PH51U20PSGW	The logo appears and turns off, you cannot update	Low supply, 100mf x 450v capacitors exhausted, replace both		VICTORINO
PHILCO	PH55A17	LED power supply	Ci driver	Direct equivalent of the fan6755 integrated circuit is the LD7750	davi.sls
PHILCO	PH39U20DSGW	TV doesn't turn on without STBY.	Short v plate with	V.com board short, diode d109 ( ls 67 lg ) above the lvds cable.	RNSPTEC
PHILCO	PH40U21DSGW	Turns on after 1 to 2 minutes turns off	Corrupted software	Software update resolved the issue	Gilberto Costa
PHILCO	TV PH21C	Alloy with the weak negative image drizzled as if it were the tube	C845	Replace the 1000μF 16v c845 replace without fear	Sinailson
