PHILIPS Repair Guide: Common Issues and Fixes

Brand	Model	Fault	Detailed Problem	Solution	By
PHILIPS	21PT5433/78R	The TV doesn't turn on, there are several methods to analyze, in the case of the Philips it has two pre-transistors	How to measure the voltage in both, first-7423pnp is connected to the driver transformer the collector has -b 8v, the b 5.2v +b the emitter 5.5v +b this means that the transistor is poralized correctly, remember this measurement is with the TV on the 7422 is connected to each other the b receives the signal coming from the ic does everything, voltage on the collector 3.2v base 0v this transistor is poralized with the sawtooth signal. now the measurements in standy bay, 7423 c 0v -b emitter 10v +b base 10v +b means that now the transistor is cut off the output voltage on the 7423 collector is 2v signal with the TV on, with the TV in standy bay we will not have the 2v signal		Miltom eletronica micro e epron

PHILIPS	DVP3254K	DVD with very low sound	Ce26 de 220uf16v	Replace	Eletroclaudio Aguas Belas PE
PHILIPS	21PT9467	Vertical closing after about 5 minutes	TV works ok, after + - 5 minutes the vertical closes at the top of the image, consulting other colleagues and also doing tests I came to the conclusion that the deflector was the defect	The right thing to do would be to replace it, but it is not sold. I did the following: I removed it from its place and on the inside of the deflector there were two stickers. One came out well, the other was well glued and dry, I believe that due to overheating, I removed the adhesive, cleaned the winding with thinner and then applied spray varnish, it worked ok	Tecnardi
PHILIPS	42PSL5332	No audio	When turned on, there was a normal image, but no sound. The detail was passed by a Philips authorized representative and as they found no defect, they condemned the main board.	1Ω smd resistor. As I didn't have the resistor location number, to help locate it, it is close to the female input jack (audio in PC) the resistor was open	José Gusmão

PHILIPS,CCE,SONY	VALIDO PARA AS MESMAS		TVs turn off so quickly that we have no idea where to look for the defect, here are some tips. You will use 3 diodes in4148, connect the anodes to the connector that comes from the main board to the tube board pin1,2,3 and join the cathodes and connect to pin 5, ready, the TV will no longer turn off, you will see the corresponding defect on the screen. This applies to the brands: Philips, CCE, Sony. In the case of Sony, we use 1k by 1/4W resistors, we connect each one to the RGB resistors We join the 3 ends and solder them to the connection, cool, in case the TV turns off so quickly that we have no idea, as already explained where the defect is, this tactic will release the plot faster on the screen, generally it takes 10s to release it, we reduce it to 4s You will use an 800m 6+6 transformer, connect it to the filament, wait for the cathodes to heat up and turn on the TV. There will be a way for you to access the error code and view the plot. There is a way for you to view the corresponding defect on the screen or how to access the error code. ex:0 0 0 0 0 how is 0 0 0 0 0 it means that the TV is working correctly if a number appears it is a sign that the TV is defective in another stage, the error code counts from left to right ex: 9 0 0 0 0 this 9 points to the eeprom memory or it is defective or lost or even a lack of power. a 10k resistor in the case of sdam1 sdam2 connect a short circuit from one to the other and turn on the TV when it starts remove the short immediately the TV will turn on in service mode this is either without the TV's CR or the TV is not turning on alone The LED turns on and the LED indicates the error code, eg: 9 blinks correspond to an error.
