Brand Model Fault Detailed Problem Solution By
PHILIPS14PT3131/4131/3331/4331
Volume from minimum or maximum.- check circuit to eliminate "plop", mainly diodes 6908, 6909 and capacitor 2909.
PHILIPS14PT3131/4131/3331/4331
Volume does not go down completely.- check possible alteration of diode 6906 (1n4148), probably open.
PHILIPS14PT3131/4131/3331/4331
Vertical closing intermittent.- check capacitor 2464.
PHILIPS14PT3131/4131/3331/4331
Vertical closing intermittent.- verificar service information ts04-016.
PHILIPS14PT3131/4131/3331/4331
Vertical closing intermittent.- check capacitor 2461 (1nf).
PHILIPS14PT3131/4131/3331/4331
Vertical closing intermittent.- check capacitor 2460 (see service information ts04-016).
PHILIPS14PT3131/4131/3331/4331
Vertical with little amplitude- check transistor 7461, replace if in doubt.
PHILIPS14PT3131/4131/3331/4331
Vertical with little amplitude250v) code 2222 479 47207 (see service information ts04-016).
PHILIPS14PT3131/4131/3331/4331
Vertical with little amplitude- check capacitor 2460 (68nf 100v), temporarily the capacitor will be damaged by heating, in this case the stations are being advised to replace the capacitor with (68nf
PHILIPS14PT3131/4131/3331/4331
Voltages below the specified (vo, +b,..)- check possible alteration of resistor 3453.
PHILIPS14PT3131/4131/3331/4331
Voltages below the specified (vo, +b,..)- check possible changes in the 1k 3525 smd resistor connected to pin 9 of the ci 7250.
PHILIPS14PT3131/4131/3331/4331
Voltages below the specified (vo, +b,..)- check possible changes in the 1k 3525 smd resistor connected to pin 9 of the ci 7250.
PHILIPS14PT3131/4131/3331/4331
Voltages below the specified (vo, +b,..)- g2 does not work, check 5441 tsh.
PHILIPS14PT3131/4131/3331/4331
Voltage varying.- check possible alteration of transistor 7523 or 7515.
PHILIPS14PT3131/4131/3331/4331
Voltage varying.- check possible changes in the 1k 3525 smd resistor connected to pin 9 of the ci 7250.
PHILIPS14PT3131/4131/3331/4331
Dark screen - no image or active progressive- check ci 7641, in this case it should show normal dos.
PHILIPS14PT3131/4131/3331/4331
Dark screen - no image or active progressive- check the possibility of altered/open resistors 3443/3444.
PHILIPS14PT3131/4131/3331/4331
Intermittent sound (crashes, hiccups) or no sound.- check smd 2202 capacitor pin 32 and 33 of the uoc.
PHILIPS14PT3131/4131/3331/4331
Intermittent sound (crashes, hiccups) or no sound.- check 4.7nf smd capacitor position 2201, and it is common to have a failure on one side.
PHILIPS14PT3131/4131/3331/4331
No tune = channel/station just noise/mute.- check possible alteration of resistor 3349 (27k). see item 5.7 repair tips in the service manual pg. 20.
