Greetings friend Manolo probema with philips model 21pt6456 / 44 tda93
Since you turn on the TV and it lasts on, enter servi mode and see there what error throws you. Comment it You can even delete it. With the cleean. And see how it works.
It does not say if you touched the scrin, many do it to see if something manifests on the screen. If this is the fault for which you are repairing it or had another one and it is the same now.
This is the SCRIN, if it does not have a good fit it makes such a failure.
Do you have a good image and audio?
It has good image and sound only for a few seconds that does not give time to enter the service mode, the repair was for the flay in court thanks
Decrease SCRIN and see if it takes longer on.
Ni Bien des PW press 062696 MENU. And you will see on the screen if it has an error. Because if you can see the image you will also see the servi mode.
Thank you, but the time that is with image is very short to see details of the srvi mode.
Yes I know . That happened to me several times. But just as you can see the image you can also see the way I saw it. Because when you start the TV it will show you the servi mode directly. Do not put antenna signal.
You don't say if by decreasing the scrin bit by bit and turning on the TV again, it stays on longer.
Greetings, we reduce the screen to 300 vol and nothing, life remains the same, I continue with my concern that at the reference point that is in the socket there is only 3 vol and when I press and hold the channel change does not turn off. thanks
Do this. Since you do not insist entering the way I saw.
Put the tester where you say you have 3v and turn on the TV and do not stop changing the channel to see how much the tension is
Thank you, I insist that I cannot enter the sevi mode. because there is no time for anything, it is only seconds what you see, there is some method to enter and it takes time to see something of the sevi. At the moment when the channel changes at that point, the voltage varies between 3 and 12 vol. When the change is released, it keeps the 3 vol.
I will ask you this question first.
When you give PW how much time does it take to get an image?
Answers
The time it takes to exit the image is 11 seconds and the image remains instantaneous.
11 sec. More than enough time to enter servi mode and watch the diasnostic car provided by the Error Buffet TV. This is important to do. It will indicate the problem of the tv.
You must check that all the buttons on the remote control are working fine. That is the numbers:
062596 and that of MENU. if one of them does not walk, it does not enter the buffet or serve mode. Okay. You must give PW and dial the code immediately. So do not show anything on the screen because it lasts 11sec in giving image. Do not place antenna.
I thought you had already solved. It turns off is due to excess tension on the screen Bajala from 300 to 350 Volts
I already told him to reduce the voltage to the point that he sees that it does not turn off or that the TV lasts longer. The rare thing is that if you have the scrin elevated, you should have delay lines and he never mentions them.
when I raise the screen voltage up to 500vol there are no delay lines, just to test, I keep it at 350vol.
The tensions are. + B117 vol video 190 vol scree 420 vol before brightness, on the micro
pin 14 7.6vol pin 34 0.4vol pin 36 1.8vol pin49 2.9vol pin 50 3.0vol on this pin what I estimate should be between 5.1vol minimum and 7.7vol maximum.
Then I tell you if the diagram you send me corresponds to that of my tv, because here the connection is slow.
And the 5v are present in the god or 6681 in his cathode? Try changing the diode.
Before you can give PW and put the TV in AV mode WITH the control. Then as it turns off just follow the steps indicated above.

Greetings I managed to enter the serv mode. for moments and I had the error 11 32 00 at that time I also managed to raise the cathode values a bit that caused the voltage to rise at the reference point of the HAAA socket .. with a condition disconnecting diode 6624 which is what brings the reference of the vertical output, with the diode disconnected there is 5.1vol on pin 50 of the micro but it goes off, I repeat on the vertical there are -12vol and 23.5vol and 0vol output, in the reference for diode 6624 - 7vol. In the diode 6681 that indicates me there are 4,7vol.
I have the trc tester and and it does not reflect short with the filament however we will perform what we advise we follow.
Greetings, the problem of turning off the detail was that the reference voltage of the vertical was very high, I managed to lower it and resolved. I still have a detail that looks very dark although the brightness rises to the maximum and I raise the screen to 525 does not clarify what enough and the delay lines do not appear. The ik does not work but it was resolved with the diodes. we follow.
Take the measurements in ABL and it has 6.4vol at the point at the exit of the flay after the resistance, but I still get the attention that 525vol on the screen and the delay lines and lack of clarity on the trc do not come out and I measured the emission of the cathodes with the trc tester and have an emission greater than 80 percent, the filament voltage is 6.1vol, which will happen.
The truth is that this voltage of 525V is a lot - did you change the 2 filters of + ¡b and chroma?
