Make	Model	Symptom	Problem
PHILIPS	20CN4066	Vertical with three white lines at the top of the screen	Change the electrolytic capacitor 100µf × 25 volts (c-400) step to detect the defect: this defect is almost always this capacitor with little capacity (dried out over time)
PHILIPS	20CN4066	Vertical running	Change the 4.7µf × 63 volt electrolytic capacitor (c-868) step to detect the defect: this defect is almost always this capacitor with little capacity (dried out over time)
PHILIPS	14GL1010	Vertical running without volume and the volume bar locked	100pf ceramic capacitor shorted c-930 step to detect the defect: it was found that the voltage on the ts-180 collector was low at 1.8 volts when metal was touched on the emitter of the same the television worked normally but at bar was stuck, followed the printed circuit and found two diodes in series connected to a pin on the processor integrated circuit and a resistance to ground and one in series connecting to the IC pin with a ceramic capacitor to ground in the schematic it said that The CI pin should have 4.5 volts but it only had 2.2 volts so the defect was the shorted capacitor c-930.
PHILIPS	20CT6558	Goes off with sound and if you increase the voltage on the scree grid it lights up but there is no image:	Open printed circuit track well below the b017 battery; caused by battery acid leakage. step to detect the defect: it was verified that the voltage at pin 8 of the integrated circuit tda 3561 (ic-292) pulse sand castle was 1.4 volts when the plug of connector n3 of pin 8 was disconnected, the television turned on normally. A visual inspection was then carried out on the form and it was observed that it had an acid leak mark. After cleaning it, it was found that the form was open.
PHILIPS	ZOCT-5455M/UV	Weak image without contrast and out of vertical and horizontal synchronization.	3.3µh shock open s-156 step to detect the defect: in this case there is no option and just put another one on top and check if it works.
PHILIPS	ZOCT-5455M/UV	When it turns on it turns off	There is sound and the tube filament lights up, there is high voltage. only lights up after 30 minutes electrolytic capacitor c-232 150µf × 16 volts or c-565 0.1µf × 630 volts (100k polyester) step to detect the defect: in this case there is no option and just put another one on top and check if it works .
PHILIPS	20CN4466 VHF/UHF E 14CN4416 VHF/UHF:	Burning duct 11 at 110volts and 220volts works normally but, with black bars in the image	C-319 from 3k9 ceramic. step to detect the defect: in this case there is no option, just put another capacitor in place, don't forget to remove the old capacitor as it gets in the way if it leaks.
PHILIPS	20CN4466 VHF/UHF E 14CN4416 VHF/UHF:	To eliminate the u100 autofountain board	Just place an in4007 diode connected with the anode on pin 2 and the cathode on pin 3.
PHILIPS	20CN4066	Off, beeping softly (squeaking)	Integrated circuit tda 2577al step to detect the defect: voltage in the collector of ts 355 (but11), equal to 347volts and in the emitter of the same 29.2 volts verified at r 338 (1w) replaced the c323 (2207µf × 10 volts). redone as solders of the tsh (flay-back t - 564), the driver transformer (t-335) and the tda 2577al integrated circuit (ic - 875). and it didn't work, to solve it, the entire integrated circuit (ic-875) was finally replaced.
PHILIPS	16CN1435	Very bluish color with ripples at the top of the screen disappears and appears suddenly	Changing c-220 of 560pf step to detect the defect: it was by assumption that it was enough to change and the defect was resolved.
PHILIPS	16CN4435	To adjust the pp	Do the following. First adjust channels, brightness, color, contrast and volume, then press store on the TV and also hold down the key and press pp on the remote control, hold down both keys for 30 seconds then release both together, that's it.
PHILIPS	16CT6410/UV	To memorize pp.	First, do the following, adjust all the device's functions to the point you think is best, including the volume and channel you want it to turn on via the pp. then press the store key, then the pp key and then press the execute key on the device, the key press time is 2 seconds. other models see in this section and also in item iv memorizing pp, etc.
PHILIPS	20PT324A/78R	It doesn't turn down the volume it always stays on high	It was the exit tda7056b
PHILIPS	14 GL 1316	Does not receive video (a/v input)	By ci 8361 the video input is on pin 15, but the release of the same is done on pin 16 through tr.7203, which receives the micro command coming from pin 36 of the micro. I would continue with the oscillation. video signal to pin15 of the 8361. and checked the tr 7203 if the micro command is coming from the base and pin 16. Now I re-read your question and it seems to me that from what you explained, the defect is in the input block, with the oscillation. and just follow the signal in tr 7021, and 7023, 7024. I hope I helped.sds. milton2001 from rsdica sent by: lino---matuto
PHILIPS	20PT120	When plugged into the socket, it would blink and the LED would remain on when activating the channel, but the LED would blink 5 times, and it behaved like this when pressing the channel again, as many times as desired.	Solution: 24w04 memory
PHILIPS	20PT220A/78R	When plugged into the socket, it blinked and the LED remained on when activating the channel, but the LED blinked 5 times and when pressed again it no longer blinked, keeping the power supplys normal.	Solution: it was the flyback
PHILIPS	20TP 120A	It was working, only on cable TV it only got channels above 43 on VHF it didn't find channels,	I changed the selector and the TV worked again ok!!! tip sent by: jair fco. silva teresópolis r/j
PHILIPS	14GL1010	Loses horiz synchronization. and vertical, sometimes without high voltage. 1k r505 overheated	Capacitor c 130 (4.7 u f x 63 v) with loss of capacitance or high esr
PHILIPS	CN	Retrace lines at the top of the screen	Capacitor c 400 (100 u f x 25 v) with loss of capacitance or high esr
