Philco Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILCO | PCX6000 CAIXA AMPLIFICADA | Doesn't start | Shorted mosfet transistor q16 | Replace and repair. | JC Eletrônica Cícero |
| PHILCO | PH28N91D | Turns on with sound, weak backlight | Open led | Changing the bars | JC Eletrônica Cícero |
| PHILCO | PH21 SS | 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 | PH674 | Doesn't start | 5v pulsating power supply. | Tl431 | Baguatech |
| PHILCO | PHT660N | Mutes sound at high volume, mutes sound from all channels | Subwoofer replacement, coil shorting out when it moves... | Audiotec Londrina | |
| 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. | MIGUELTV |
| PHILCO | PH39U20DSGW | Tsound is no image, back light comes on | Heat vcom ruler next to ci u606 | In my case, the image returned. | Mariano |
| PHILCO | PME31 | Membrane does not work | Shorted display, remove it if it works, get another one | reginaldo moronte,eletronica junior caldas novas | |
| PHILCO | PH39N91DSGW | Dark screen, does not turn on backlight. | Desoldered lw802 coil fallen out. | Replace the lw802 coil as the old one was very hot. | Hilário Sperling |
| PHILCO | PH28T35 | I'm sound | It arrived with the r621 (10r) open and capacitor c622 (220uf x 35v) inflated. | Capacitor c630 shorted causing r621 and c622 to burn. I replaced the components and the TV started working again. | CRISTIANO DONINI |
| PHILCO | PB120N | It doesn't turn on and only the clock stays on | Torque wrench | I replaced the touch key and it was great | alfredo nemecek |
| PHILCO | PHT10000 | As soon as you plug it in, it turns on and off | +33v low power supply | Resolder or replace the c942 and c944 electrolytics at the power supply output | Alexandre Oliveira |
| PHILCO | PH21M SS | Stand by blinks on and off tv - doesn't work | D813- | Replace d813 --fr104 = fr207 ok | EMERSON RIBEIRO |
| PHILCO | PH42F10DSGWA | Does not increase audio, stays at 0 | Reset enter smart tv configure and restart works 100% | Eletrônica alternativa mijail | |
| PHILCO | PH21 SS | Green screen, with lines | The tube lacks blue color, replace the 2sc2688 transistor that powers the tube's blue pipe. | Replace the 2sc2688 transistor on the blue tube plate. | MARCONES DE ARARIPINA-PE |
| PHILCO | PH32E31DG | Don't care, | C2d7 c1d9, c2d6 capac 100yf 50v replace todos | Replace | molina |
| PHILCO | PTV43E60SN | Backiligt sometimes lit up sometimes not LED bars changed | Capacitor cb9 removed and placed 100nf works even without capacitor | cmteck eletro | |
| PHILCO | PH39F33DSG | Stand by access and does not turn on | Checked the soldering of the power connection on the main board. it was oxidized | Removed the weld and made a new one, problem solved | ANTENISTABNU |
| PHILCO | PH32U20DSGW JUC7.820.00122532 | Turns on normally, functions via the keyboard ok, but does not follow the remote control. | Capacitor on the ir receiver board, c973 grounding the signal | In my case I just removed it and the TV started working again, it is connected between the IR signal pin and the GND, so it should be 10pf. | MARGUTEK.BVA |
| PHILCO | TV PH22D16D LED | High LED voltage | Factory characteristic, which reduces durability | Replace the smd resistor connected between pin 6 and gnd of the LED driver ci, the ob3363vp, with 16 pins, I put one of double the value, the current dropped by half. | davi.sls |
