"How would one determine specifically which electronic component(s) on the circuit board needs to be replaced? That is why it is much simpler to replace the board. JMHO"
Any competent electronics repair facility has the proper tools and knowledge to make the determination, it's not a difficult task
Same as folks tossing away inverters & converters. To repair a converter it typically takes less than 20 minutes and less than $2.00 in parts to get them running again better than new. Just finished repairing a Xantrex Prosine 2.0 Inverter/charger <$10.00 in parts and 1 hour labor a few FET's and caps and the unit is in great shape.
I just hate to see good equipment tossed in the trash.
