The TV just stays on standby and when you turn it on it flashes 4 times and goes back to standby againIn this case, what I caught was simply an unusual occurrence. The TV had already been screwed by someone else and the technician's horse left a bridge connecting the horizontal driver with a clue of ours that it was hard to find out, see, just find out because I went to measure the impendances of the drive and it was going directly to all the pinsJust remove the bridge and it works fineThis email address is being protected from spambots.

How to test the verticalThe vertical one has two transistors, they are called married one npn another pnp the collector of the npn has 20v +b the npn has 12v -b in the middle of the two transistors we have to have 0v you can measure it on the connector itself that goes to the deflector coil if one appears voltage, the vertical circuit is defective and it could be the transistors, some component around them connected to them or the IC does everything that is not providing the sawtooth etc.Miltom eletronica micro e epron

The TV doesn't turn on, tsound are several methods to analyze, in the case of the Philips it has two pre-transistorsHow 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 signalMiltom eletronica micro e epron

Vertical closing after about 5 minutesTV 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 defectThe 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 tsound 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 okTecnardi

No audioWhen turned on, tsound 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 openJosé Gusmão

TVs turn off so quickly that we have no idea wsound to look for the defect, sound 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 wsound 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. Tsound will be a way for you to access the error code and view the plot. Tsound 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.Miltom eletronica micro e epron
