BRAVO DUDE! I have a 16.0.2 that I am working on. I will replace 5V regulators and a bulged cap on power supply. If I can't fix, I will bring to you in Manila. I live in Guimaras, Iloilo. You seem to know your stuff as you have demonstrated. How to contact you?

anu po cause bakit nasisira yung output ic?

[@FixYahTv]

The most common fault is shorted cables or audio snake box. shorted cable stresses the i'c and damages it eventually.

[@billyballon7811]

I dont think so,small value of capacitor connected in series going to the out put…

[@billyballon7811]

Can you repair my TF5 yamaha digital mixer power supply ok…

[@stagelifeeventmanagement4858]

Hi dear I have a problem my 32ai presonus last 32 Channal have no audio after input

[@FixYahTv]

Can you gave me more info about your unit?

[@stagelifeeventmanagement4858]

Ya sure Yes, yes, man, once it happened that I was in a show and there was a problem of power fluctuation, the earthing was very high, so I was checking the income with the tester, and by chance, the auxiliary input was in the wrong channel. On the channel number 32, as soon as I put the tester on it, it has shorted the negative and positive, so a slight spark and the IC of the channel went off.

[@stagelifeeventmanagement4858]

@@FixYahTv If it is possible that the input of that channel is actually when I plug it in, then the gain and its cue are running but the input is not inputting in that channel. The input is not working and there is another problem when today it happened. As soon as I do it, it is 32 by 32 channels. So that is probably a grounding problem
