Power Supply PCB Check Flow Chart
Check the following parts first: F801, ZNR801, IC801, D801, D802, Q801, T802 and IC802.
This comes from our experience with experimental tests. For example: power supply and lightning surge voltage test, withstanding
voltage test, intentional short circuit test, etc.
Caution:
If you find a opened fuse in the unit, do not turn on the power until you locate and repair the faulty parts (except for the fuse);
otherwise the fuse will open again and you cannot pinpoint the faulty point.
In most cases, the symptom is that nothing is output. It is more likely that the fault is in the primary side rather than the second-
ary side. Check the primary side first.
