Laser Current Check * Perform this check only when the laser is faulty. 1) Connect a digital multimeter across the resistor R541 (10 ohms). 2) Playback TCD-782 and check the DC voltage value of the 3) 4) digital multimeter. Check the SPEC VALUE specified on the label of pickup. Calculate the laser current (Iop) by diving the DC voltage value across R541 by the resistor value (R541 = 10 ohms). Check that the laser current (Iop) is SPEC VALUE ± 10 %.
