Make	Model	Symptom	Problem	Solution	By
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
PHILCO HITACHI	PC1441 CPH04	Tune keeps searching for channels and doesn't tune in to any.	Ta8690 integrated circuit.		Willian8952
PHILCO	PCS2952N	Defect only in the video of the av, the image appears at the bottom of a colorless gray screen, you can only see the figure.	Ic480 ba7021 video keyer.	Replace, if you don't have the ba7021 it can be the la7221 which is a replacement.	Willian8952
PHILCO HITACHI	PC1441 CPH04	Escaping both low and high channels when it is cold, when it heats up it works normally.	Capacitor c110 de 100pf	Solution: replace the capacitor with another of the same value but with npo coefficient.	Willian8952
