First... Make sure 120 volts is getting to the converter module.. It eats 12o after all. Then there should be some fuses about,, Check them
IF you determine the converter portion of the power center is bad you can replace JUST IT without replacing the entire unit.. I recommend Progressive Dynamics series (match the last two digits as close as possible with your Parallex)
Your parallex is a single stage unit (Assuming it does not have a model number ending in "T") so it takes a long time and never quite re-fills the battery
The PDI is a wizard controlled replacement that is a 3-stagewith an added feature..This is one major improvement.
