Philco Repair Guide: Common Issues and Fixes
| Brand | Model | Fault | Detailed Problem | Solution | By |
|---|---|---|---|---|---|
| PHILCO | PH28S63D | No image. audio only. | Cold solder on the inverter and bad contact on the con3 connector (back light). | To avoid return, I replaced the current of the LED bars. I placed another resistor in series with r119 (2r2 + 1r). the 129v voltage dropped to 125v, and the bus current was 124ma and dropped to 89ma. | Eletrônica R-Tec |
| PHILCO | PH32F33DG | Turns on and then turns off | Voltages ok boards ok, defect in an LED or one of the buses | I disconnected the red LED wire from the board connector and the TV turned on normally, strange but it worked | |
| PHILCO | PH32F33DG | Turns it on, philco appears and turns it off | Tested power supply was ok, all voltages, leds ok, no visible damage to the boards | Side buttons corroded with rust along with the button plate. just replace the board or rebuild it with new buttons | |
| PHILCO | PCM1446 | LED blinking and won't turn on | C722 dry 470uf/16v | C722 dry 470μF/16v | MARCONES DE ARARIPINA-PE |
| PHILCO | PH32M4 | The TV had a pink or reddish screen. | A jammer was made on the v-con board on the resistor (rd51) and the TV returned to working with the image correctly. | Mkps | Marciok mkps |
| PHILCO | PH24M LED A2 | Doesn't start. Not even the LED lights up. | Power supply with low and pulsing 12v line, between 11.2v and 11.4v. | Solved solve | Eletrônica R-Tec |
| PHILCO | PTV32D12D | No image. | Connector on the back light is faulty. | I removed the rb840 inverter resistor (4r7). the measurements were 61.7v and 248ma and then it was 59.1v and 178ma. I made the replace to avoid return. | Eletrônica R-Tec |
| PHILCO | PTV43E60SN SERIE B | Does not turn on back light | Ci u81 | Replace ci u81 | central audio e video |
| PHILCO | PH24M LED A2 | Doesn't start. Not even the LED lights up. totally dead. | Power supply. IC1 (LD7531A SMD). little regulator with 6 legs. I didn't find it new in my city. So, I scrapped it. | Eletrônica R-Tec | |
| PHILCO | 24M | I'm sound | Capacitor de 1000x10volts e1500x25vol | João Marques | |
| PHILCO | PH32E32 | After a while it was turned on, the backlight turned off. | R98, 680k, with low resistance. power supply board near the LED drive | Stiltec | |
| PHILCO | PTV49F68DSWN | Connect to the network, turn on stanby, press power, the TV turns on but no image, the backlight does not turn on, tsound is no time to measure the backlight voltage at the power supply. | When disconnecting the wire that goes to the "adj" position of the power supply (pin that comes from the main board) and shorting this adj to the "pson" the TV releases the backlight but still no image. | This model is the same as Sony TVs, when tsound is a short in the tcon and/or display, the processor blocks operation and acts as protection. the defect was in the tcon, those 10μF smd capacitors in position c427/428/429 | MIGUELTV |
| PHILCO | PH49U21DSGW JUC7.820.00167500 | TV turns on the sound of the channel and image in the background, but the blacklith does not turn on | Short in backlight circuit | Replace ub1 (mp4010) db1, db2 (sk320u) db3 (15v zener) qb1 (mdd14n25) rb9, rb8, rb7 and rb6 (0.33r0.33r0.33r and 0.51r all resistors in parallel) | Felipe Francisco (Gov. Valadares) |
| PHILCO | PH14 | TV stopped, won't turn on after a while. | Shorted capacitor, on the 5v line. c217 of 470uf/16v close to the microprocessor. | After changing the TV ok. | George Pontes |
| PHILCO | PB126 | Radio keeps changing the frequency alone | Replace q1 s8550 | ||
| PHILCO | PH28D27D LED | Turns on the logo appears and turns off. | Defective LED bars! LED burned out or shorted | This TV uses 3 bars in parallel with 5 6v LEDs on each bar, so each bar only supports 30v. in my case the power supply was sending 32.5v! 1st replace the LEDs or bars. 2nd lower the voltage on the LEDs to 29.2v by removing the 2r2 smd resistors (rb13, rb14) good luck. | EvandoViana |
| PHILCO | 40L2400 | Turns off after about 30 minutes. | Voltage regulator n803 (1117-1.5v) which is next to the processor, dropping voltage on the in pin. As it heats up, the voltage drops and heats up the resistors r831 and r832 (both 15r/2w). | I turned off the LED chain to prevent it from returning. | Eletrônica R-Tec |
| PHILCO | PH21SS | Turning on and off repeatedly, with vertical closed | I replaced the c549, problem solved, I turned it on and it worked perfectly | GBSAT ELETRÔNICA | |
| PHILCO | PH21M SS | TV turns on with 3 colored lines at the top of the screen | Vertical filter capacitors | Replace them all | ASSISTEC |
| PHILCO | PH21M SS | The TV arrived without turning it on, just with the LED on, when I pressed the power key it turned off the LED and turned it on again but it didn't turn on | The cause of the defect was the shorted vertical ci tda-78141 | After changing the ci the TV works again | ASSISTEC |
