Philco Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILCO | PH32F33DG | No image | With the oscilloscope, notice the back light gives a pulse and disarms, change the changed LED and remove 033 resistors | Warley cesar | |
| PHILCO | PTV43E60SN | LED panel malfunction | I did all the testing procedures, I changed the mp4010 control pwm ci, I changed the smd coupling capacitors of the circuit and nothing resolved it, I went to check the smd resistors of the circuit, to my surprise I found a resistor that had not been changed but had a mounting error on the pci. presented with value (1k) but in the service manual the value is (10k) I replaced it following the service manual and it worked perfectly | Resistor in position rb16 on the pci value of (1k) in the service manual value of (10k), this blessed component is next to the smd capacitor cb5 on the fb line of the control pwm circuit | RUBERTAN |
| PHILCO | PH21USA | Black stripes on the screen after a while | Ci of vertical stv8172 when it gets hot | Replace stv8172 with la78040n | Marcelo Pitraco |
| PHILCO | PH19 | It doesn't turn on but the LED lights up | Faulty power supply | Ec3 47/100 volt capacitor. replace ele. | Parana tv concertos |
| PHILCO | PTV 22G50D | Don't turn on dead tv | Short in the dc converter responsible for the voltage of 5vs, capacitor ce4, 22mf x 6.3 shorted near the audio output | Roberto eletrônica curto circuito | |
| PHILCO | PH42B25DG | Burning the LEDs reduces the current | Https://youtu.be/ppw61tzzbay | Https://youtu.be/ppw61tzzbay | Eliel Batista |
| PHILCO | PTV43E60SN LED | Don't care! voltages fluctuating | Shorted dp10 diode. I put it in and it burned again. Then I placed two diodes in parallel that I took from a Samsung TV power supply. it worked fine. good luck to everyone! | Eletrônica Cecé. Brumadinho MG | |
| PHILCO | PH28T35D | Does not tune channels on and off | Capacitor 622 on the main board of 220mf at 35v. replace it | Flavio | |
| PHILCO | PTV50G60SN 4K LED | Reduce LED current | I removed the 0r56 resistor rfa33 and inserted a 1r5 one. the voltage dropped from 120v to 108v. good luck to everyone | Eletrônica Cecé. Brumadinho MG | |
| PHILCO | PH671N | I'm sound | Check voltage negative 12 volts. 2 capacitors in this line 100×16 shorted. | Jocimar | |
| 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 |
