    Hello, boys.

    We have Topsetter TP102, which after moving to another place has been featured defect. In calibration mode, about 1 minute after the start of the calibration appears (E4e04: Excessive current in the LD drive (driver board 4)).
    Changed the driver boards places, but always appear in the same error. Except fourth LD board out, it even sun disconnecting the LD output. The calibration of a single diode, for example first, the same error. Checked the power supply U6 in calibration mode, the voltage at all times stable - 5.3 V.
    Maybe you have some ideas on how to locate the fault and determine what exactly is broken?
    Thank you.

    Hi sir:

    You said : The calibration of a single diode, for example first, the same error. Checked the power supply U6 in calibration mode, the voltage at all times stable - 5.3 V

    This are Regulated Power Supply, the Voltage must be +5.00Vdc or Max 5.01, if you have 5.3Vdc, is faulty the power supply you must repair it or replace the electronic board, otherwise you can replace ALL electronic board, and always you will have the same problem.

    Strong recommend you, that you check the other Regulated POWER SUPPLY, if there are in tolerance 0.7% up or down !!!, when you are troubleshooting NON-Regulated power supply the problem is a little different !

    Of course you must measure the INPUT Vac, and must be in tolerance about 10% up or down, otherwise, you have the problem to damage other power supply, and Install Stabilizer Voltage in the Input of the machine.
