PHILCO	PH21MSS	It doesn't turn on, I press the power button to turn it on, it makes a noise like it's flyback and the 115v appears and drops, and it doesn't turn on	Replace diode d404 fr104, next to the horizontal transistor. and ch,c412, 391		DJ PITUKA
PHILCO	PH32U20DSG	Does not turn on or stand by	C999 (smd) shorted		Eletrônica Heinz
PHILCO	PH21M SS	Turns on and as soon as the image appears, it turns off and the LED starts blinking.	100uf capacitor in the middle of the board, close to the vertical, c 847 of 100uf/25v, with low capacitance (40uf).	It was a lot of work, but after the replace everything was ok.	George Pontes
PHILCO	PH43C21P	When plugging it into the socket, the LED on the controller board blinks twice and dies, nothing happens. Power supply board ok. Zsus board ok Ysus board with IGBT transistor - gt30j127 shorted	Remove the piece and check that it is not shorter and replace it	Defect resolved	glaydysom
PHILCO	PH42F10DSGWA	Does not tune in channels, or tunes in few channels	Defect in the tuner circuit on the main board.	Replace ci position ut2 ci r842. A defect in the CI causes problems with tuning. ci removed from scrap.	rafaelmoraes99
PHILCO	PH42LED A2 E41CO-PWG1XG	PFC standby power supply only works with low voltage approximately 300v or less	1megahom resistor changed to less with a value between 700 and 800k r302	Component replacement	Joelquin51
PHILCO	TV PH20N91D	Some o audio	Capacitor c132 with leakage near audio output u6		Alek
PHILCO	PH39F33DSG	Turns off by itself after a while	Ci viper 17l and electrolytic capacitors from the 51v line	Replace without testing the viper 17l and 100x100 capacitors c411 and c417	Luiz Claudio
PHILCO	PH39U21DSGW	Turns on with a buzzing sound on the display board. measuring the voltage at the vcon input it measures 8 to 10v when the correct one is 12v.	Q808 leaking. It is between the processor and the LVDS cable socket	To replace. I used a "pmv65xp" from another philco board. p-channel MOSFET.	PEDROTEC
PHILCO	PH40D10DSGW	Backlight does not light up.	Diode in the backlight supply on the board shorted	Replace the diode.	Antoni Garcez
PHILCO	PH21MSS	Turns on and off with vertical closed	Vertical closed because the voltage of 14+ from the power supply 810 diode changed was missing	Changing the 810 diode and solving the problem, the TV no longer turned off and the vertical April was normal	chagas galvão
PHILCO	PH21MSS	Turns on and off with vertical closed	Vertical closed because the voltage of 14+ from the power supply 810 diode changed was missing	Replaced the 810 diode and resolved the TV turning off but vertical April normal	chagas galvão
PHILCO	PH21SS	It doesn't turn on, the standby LED turns on, press the button on the channel keyboard, the LED goes off and doesn't turn on, the power supply remains at 20V, it only turns on via the control	Rewrite the memory		DJ PITUKA
PHILCO	TV PH 14C	Dark screen with characters and sound and no image	Vd 461 ( diodo zena 1n 4148 )	Replace	Eletrônica Mauro Mascarenha - Parazinho Ceara - Tel : (88)981422821
PHILCO	PH21MSS	Turns on and off, the image appears and turns off and the LED blinks	Replace q802, 2n5551, r816a, 390r e r818, 820r		DJ PITUKA
PHILCO	PH21M2	Led flashing quickly with a tik tik noise on the trafo and +b with 60v	Defect caused by r514 in the TV's primary power supply	After replacing it, the TV turns on again	ASSISTEC
PHILCO	PH20U21D	No image, just audio.	Defect in soldering the wire to the LED bar.	I started welding again. To avoid faulty feedback on the LED bars, I lowered the back light LED current. I removed the inverter resistor r814 (2r2). the measurements were 27.2v and 384ma, with back light at 100%, for 26.2v and 250ma.	Eletrônica R-Tec
PHILCO	PH21	Normal power supplys and turns on, but does not oscillate, vertical working normally	Q401 changed	Replace the q401	Fofao
PHILCO	CAIXA DE SOM PHT5000 HP00068A	Turning off after supposed power outage.	Right away, I saw that the power supply responsible for charging the battery was inoperative.	When reviewing the power supply PCI, hp00068a (same as the pht3000 and tsound is a diagram at electronia.pt) I found the photo coupler shorted between pins 1 and 2, for this reason I replaced the 431 and the lm 358, it still didn't work. good primary It had +b and pwm power arrived, I replaced the ob2273m with an equivalent and it worked, it generated 14.5 volts on the secondary, I connected it to the box system and it stabilized at 13.5 volts. resolved! pht5000 box ok!!!	Giovani PiresBitencourt
PHILCO	MSP 200	No sound, display without backlight, CD doesn't work	8v missing.	Substituir q404 (ksa928a) = bc636/bc640	Baguatech
