In your question asking for help you should comment everything you did to try to solve the fault. So what happens does not happen. In other words, they suggest things that you later say you have already done.
ok excuse me let me explain myself well when giving the power order the porwer pulser has 4.9v this falls to zero because i am giving the ignition order but for pin 24 of the micro there is no change now check capacitors and transistors resistors in the power line and everything is fine in the micro power supply voltage vdd, reset, data, clok, the voltage of + b is present in 104v
perform the test bypass the collector and the emitter of the q873 and the voltage rises to normal and the focus turns on even connect everything on the tv and this ignition but with the vertical line mount a new vertical and remain the same I think the micro is bad because it does not take out the ignition order and turning it on as I am turning it on by realizing the bridge to the q873 the micro does not work
I think you read all the input. Because you don't comment what one asks you.
As if the tv has audio.
And the tension in the flyback pin. Comment on the vertical tension. Pin by Pin
Hey yes
friend I have made all the tests that have indicated me in the pin of the flaybak voltage arrives 104v the tv does not come out of print when pressing the power button but with the last test that I realize that I indicated bypassing the collection and the emitter of the q873 voltages they raise the + b 133v 45v and 12v I connect everything again flaybak, horizontal etc, and the tv turns on but only by bridging the collector and emitter of the q873 but it turns on with vertical line the voltage in the vertical are correct anyway I am going to publish but does not give audio is not like if the micro is not working
How good you will solve it.
The forum gives you 2 thumbs. To qualify the help provided.
Salu2
that's right friend nicomena2015 the micro is powered by its pin 8 the 5v are present the detail is when I give the ignition order the micro does not send that order perform the following test unlink pin 24 of ic701 and inject 3.3v into the line and the tv turns on pro with the vertical line will do that is another point with respect to the vertical but with regard to the ignition I think the mike is damaged, also change the glass and it remains the same, a colleague told me that he had a mrico that vat to facilitate I will get it and change it
colleague ... check also the Q403 ... this transistor is the q, avilita or cut off the excitation hor, q, it comes from pin27 of lc101 ... if the Q403 has tension in its base it won't start the hor ... devs measure it and see if it is not short or open ... or better remove it from the plate and measure it outside ... when you remove it from the plate you notice if the hor stage starts ... the eeprom receives the 5v on pin8 ... pin25 of the lc101 receives its 5v supply voltage ...
sorry for the delay in responding was a coconut busy with other issues I told you that I got the micri and replace it ready all work correctly I have even the vertical does not have any type of failure maybe the vertical line was damaged because the micro was damaged and I wasn't working well, thank you very much everyone for your advice
