One fine day, my dear D-10 suddenly doesn't work. When I press Play, the LCD shows 0:00 for a few seconds and then turns off.
Check again, the source of positive + 5v is lost. Continuing to check, the 10 pin of the IC401 only has 0.9v instead of 4.6v when pressing Play, Q402 (B = C = E = 9v), Q401 (C = 0v, B = E = 9v), D401 is good, the rolls are fine.
Pin check : 3(1.23v), 4(1.23v), 5(1.84v), 11(1.34v), 12(0.7v), 13(1.2v), 14(0.2v)
Please help me!
