Hi guys, novice me again. I'm taking a gander at a 4 channel car power amp. It was given to me because one of the RCA line inputs was broken so I figured I could repair it. Changing out the RCA input wasn't too much of a problem. However, even though the amp powers up fine, I am not getting any output. Sooooo.....I opened it up again and did some precursory voltage testing. There is a bank of smaller transistors on either side of the amplifier and I checked voltage on each pin on each of these smaller transistors and I'm getting Pin1 0VDC, Pin2 12VDC, Pin3 0VDC on the first 6 on each side. On the last two, I'm getting Pin1 -0.06VDC, Pin2 0.5VDC, Pin3 -0.01VDC. Any ideas as to where to proceed from here? I AM NOT A TECHNICIAN! I am technically inclined and love to poke around and, because of all the help from you wizards, I have repaired a lot of stuff in the past. Here are a couple pix....
