ONE POINT REPAIR GUIDE

NO POWER

If the unit doesn’t work by no PVDD problem, repair the set according to the following guide.

1-2. FUSE/ FET

1-2-1. Solution

Please check and replace F901, Q901 on SMPS board.

1-2-2. How to troubleshoot (Countermeasure)

1) Check if the fuse F901 is open or short-circuit.
2) Check the anode-cathod voltage of D951 with a digital multi-meter, it is normally 0.2 ~ 0.3 V.



If it doesn’t have any voltage, it’s destroyed. Replace it with a new one.

1-2-3. Service hint (Any picture/ Remark)
