PHILCO PH21MSS
Frame reduced horizontally, more on the left side than on the right After changing the power supply capacitors and resoldering on the board I found the r306, close to the vertical one, toasted, the value of 220r was replaced, the board was even reduced. I found a L458 coil without the ferrite magnet. was replaced and adjustments were made to the service mode Mitzko eletronica

VA 		Image upside down after broken screen change. Original screen t315xw03, replaced by hv320whb from a sony. This model has several screen models in service mode, but the one I had installed was not on the list. This TV has 3 software versions. if it happens to you. check the lyrics after the series, if the OLIBIO - ELETRÔNICA ESTUDIER

Turns on, philco appears and turns off 3.3v regulator, close to the selector, leaves 2v Replace of the same Rodrigo cofferi

Turns off by itself after 20 seconds on. goes to standby. Update software and reset via service mode. rafaelmoraes99
PHILCO PH28D27D
The logo appears and the LEDs turn off, but the sound remains. Defective LED bars, burned out or shorted LED. Removing the 2r2 smd resistors (rb13, rb14) to lower the voltage on the leds to 29.2v the television will work normally. In my case, I only removed 1 rb13 resistor and it solved the problem. JKSTek

PHILCO PH14D
Doesn't start. Q881 and d891 on the reference board is a diode. However, they add a resistor, in my case it burned out and I couldn't see the colors. Just put an in4148 diode in the right place. Replace q881 2n5551 d891 (replace the resistor that replaces the diode) and place the diode in4148 Nilmar

40% below without vertical image... that is, tsound was only 60% image C563 and c562, then c406 I replaced capacitors that supply the +15 and -15 (c563 and c562, even though the capacitance was not so out of the ordinary), and the vertical image opened, but tsound were small horizontal stripes at the top (5 or 6). Then I checked the generator signal (pin 3 of the vertical) and it was altered, I replaced it and the c406 image was perfect David

PHILCO PH49F30DSGWA
Turns on but the backlight lights up faintly, but very faintly As is customary, a budget for LEDs was given, surprise when changing the kit that the TV lit the LEDs very weakly...the voltage that went to the LEDs with the defective TV: 81volts...after the voltage was resolved The LEDs went to: 117 volts.. Cw21 of 1μF smd next to the c.i drive uw4 ( ob3352cp) was shorted and also the smd resistor rw48 ( 10Ω smd). It is difficult to find the datasheet of the ob3352cp which is different from the ob3350, sound is the pinout that I found by analyzing another board: pin 1- out for the LEDs (gate in nomenclature), pin 2- gnd, pin 3- sense in, pin 4- ovp, pin 5- inn bl adjust, pin 6- cmp (i.c decoupling), pin 7- bl_on (backlight enable), pin 8- +b 12 volts.
