Make Model Symptom Problem Solution By
PHILIPS 14PT3131/4131/3331/4331
Does not work (it remains switched off). - check 6505 (zener 22v), 7520 (ci tea1506t) and capacitor 2521.
PHILIPS 14PT3131/4131/3331/4331
Does not adjust the volume (it may or may not indicate on the display). - open menu and deactivate volume limit, if not active volume limit check if it is not in hotel mode..
PHILIPS 14PT3131/4131/3331/4331
Does not open vertically - check smd 7461 transistor.
PHILIPS 14PT3131/4131/3331/4331
RGB return lines on top when powering on. - check capacitor 2460 (see service information ts04-016).
PHILIPS 14PT3131/4131/3331/4331
Return lines when calling. - verificar capacitor 2460 (68nf 100v).
PHILIPS 14PT3131/4131/3331/4331
Modification 2) solder a wire from the diode cathode to the 3618 resistor.
PHILIPS 14PT3131/4131/3331/4331
Modification 2) raise resistor 3618 (+3.3v side),
PHILIPS 14PT3131/4131/3331/4331
Modification 1) remove the 5601 coil (5.6µh) and replace it with a bat85 diode (code 4806 130 37364) (cathode for pin 54),
PHILIPS 14PT3131/4131/3331/4331
Turns on randomly - exits the stby function without command. - this symptom may occur at low temperatures in some ci 7200 versions.
PHILIPS 14PT3131/4131/3331/4331
Interference with sound or image on other devices when stb. - remove 1nf capacitor position 2585. if the product's power supply is 220v, the fet 7521 must be checked for 14" models fet transistor fqpf6n80 (9322 187 17687) and for 20 and 21" models fet transistor fqpf7n80 (9322 174 27687 ).
PHILIPS 14PT3131/4131/3331/4331
Interference in the image - check diode 6463, possibility of alteration. - check for possible lack of solder on the 3456 resistor.
PHILIPS 14PT3131/4131/3331/4331
Interference in the image - check diode 6463, possibility of alteration. - possibility of changing the power supply resistor 3547 (330k).
PHILIPS 14PT3131/4131/3331/4331
Image without definition, like weak trc. - check the possibility of changing one of these resistors 3443, 3444 or 3318.
PHILIPS 14PT3131/4131/3331/4331
Excess brightness at the av entrance. - check resistor 3181 (75r) altered or unsoldered.
PHILIPS 14PT3131/4131/3331/4331
Folding image vertically - check capacitor 2460 (see service information ts04-016).
PHILIPS 14PT3131/4131/3331/4331
Folding image vertically - device presents vertical folding in the image after some time of heating, symptom appears when the expand function is activated. see figure. a 1r resistor (code 4806 113 97046) must be added in parallel with position 3446.
PHILIPS 14PT3131/4131/3331/4331
Folding image vertically - check capacitor 2460 (see service information ts04-016).
PHILIPS 14PT3131/4131/3331/4331
Folding image vertically - check diode 6463, possibility of it being altered.
PHILIPS 14PT3131/4131/3331/4331
Turns off immediately after turning on. - check ci position 5520.
PHILIPS 14PT3131/4131/3331/4331
Turns off immediately after turning on. - check for possible lack of soldering on the 3489 resistor.
