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!

The AC9V will be split into +5.2V and -5.2V. Pls confirm both +5.2V and -5.2V are generated well. For the reason +5.2V or -5.2V is failed to generated, ordinary is caused by broken coils' legs, bad TLC1451, or +5.2V short circuit. Don't worry about the 4.6V, it's a DC bias, the pin output 50Khz PWM waveform not DC voltage. Also, check Q401 and 402 whether there's anything wrong.

my D100 has the same issue. When Play is pressed I can only see 00 on the LCD but no movements from anything.
