led 32 admiral EF3212 goes dark and the sound goes away
hello, sanfalla, if I leave it for a while without speakers? can you fuck the ic? The ic, audio does not heat the micro heatsink at all, now I turned it on 2 hours ago and the HDP jewel goes, haha, take tensions in the main on the regulator transistors
I found in one of the regulators that has type tip, smd, that when it was working I took the tensions, and when I failed in one I found the lowest values, that is, operating on one leg the right looking up 5volt. , in the middle what would be the 2.5 volt heatsink, and in the other left. 1.25, with the fault it goes to 0.70 and that of the middle 1.25 and the 5 volts on the right
I changed the regulator, I found another one on a plate, now I have 5 volts, always on the right, in the middle 3.9 volts, and on the left leg. 2volt and it's working ok, I'm going to try it and comment, I didn't notice that it fed that regulator, I don't have the circuit
It seemed to me that on that side it could be, although the 12 volts do not vary, can this be poorly filtered?
If the 12 volt does not vary, it is unlikely to be filtered but not impossible, you can replace filters due to doubts, but I am inclined to integrate the audio, maybe when heated it will have an excess of consumption and cause the failure, if it is not difficult for you lift it do it and try to see if the fault is eliminated,
What I did was disconnect the tcom, unplugging the connector, well the black image as when it fails with the LED on, and with sound and after a while I hear the noise in the speakers and the sound is cut, to discard the tcom
Ok is an option, keep in mind that it usually feeds on several pins, and you will have to cut tracks
