| PHILCO | PCM2044 | Sometimes it turns on and sometimes it doesn't turn on and the LED just keeps blinking | C706 22n close to the power supply output capacitor | edezio eletronica | |
| PHILCO | PCS-2950 | Vertical closed and burning la7838 | La7838, zd601 and zd602 next to the fly back, were changed | Replacement | Eliel |
| PHILCO | PCM-2046 | Oscillates and stops, makes a very strong horizontal noise | Pin 10 of the one chip shorted | Replace | This email address is being protected from spambots. You need JavaScript enabled to view it. |
| PHILCO | TP-2054 | Normal carioca power supply, the high voltage in the "pacifier" bursts and it doesn't turn on. | C715 with "cold" solder. | Clean it, because it's charred, resolder it, and that's it. OK? | derli souza |
| PHILCO | PH14, PH21, PH29 | Does not turn on (intermittent); turns off by itself; takes time to call; standby LED blinks but the TV does not turn on. | These televisions have the TDA11145 microcontroller integrated into their main board, it has four protections that may be activated causing the television to turn off by itself. | 1- disconnect component d315, if the television starts working again the defect will be in the vertical circuit. 2- disconnect component d412, if the television starts working again, the problem will be in the eht circuit. 3- disconnect component q403, if the television starts working again, the abl circuit will be defective. 4- perform a test on the tda11145 precisely on pin 28 if the voltage is less than 1.5v the circuit will be defective and the following components r315, r316, c317, r274 and the processor itself will need to be checked. | R. Patriarca |
| PHILCO | PH14 D/E PH21 C/D/E | Does not turn on (intermittent); turns off by itself; takes time to call; standby LED blinks but the TV does not turn on. | Check r839 (82k), with these symptoms the resistor can change to an approximate value of 100k, 1w metal film | R. Patriarca | |
| PHILCO | PH29US A2 SLIM | Does not turn on, turns off by itself or does not exit standby mode. It is common for the television to turn on, the standby LED is on, the +b line voltage rises (130v) and then drops to standby voltage (60v) | Replace transistores v502, v574, v505, v431 e capacitor c2383 | R. Patriarca | |
| PHILCO | PH21SS SUPER SLIM | Does not turn on, turns off by itself or does not exit standby mode | Check transistors v502, v574, v505, v431 and capacitor c2383 | R. Patriarca | |
| PHILCO | PH21US A1 SLIM | Does not turn on, turns off by itself or does not exit standby mode | Check transistors v502, v574, v505, v431 and capacitor c2383 | R. Patriarca | |
