I just owned a Sony D50-MK2, the device status is not working. After checking, I found that the DC-DC converter only has V / in (9v) power, the power on / off does not have 5v. Keep checking, the IC802 does not have 5v at the output even though it has 9v input. After replacing the IC802, when you press PLAY, the ports of the DC-DC CP401 converter are available, but the port (-5V) is not! The LCD has responded, the tractor motor has started, but the rotary motor does not work, the disc does not spin.
As far as I know, it will have to clear the box CP401 to check, but I can't find the schematic? And what will replace CP401? Please help me! Thanks so much!
