The power comes on and tsound is no audio. everything lit, volume control works. | I noticed that the 12 volt voltage was missing. Leaving the power supply, it normally reached the PC board, but it did not feed the audio circuits. | See transistor q 301. I replaced it, 12 v came, tsound was no audio. If you see possible bad contact on the large flat, connect the micro to the control board. After the bad contact was corrected, everything was normal. | arock |
