Replacement electrical cord

In the front of the manual is a phone number, try that for parts.

In looking at the specs the base charging adapter and the handset charging adapters are the same output, so unplug your bases power adapter and plug it into the handset power adapter and if it shows the handset charging than just order the base power adapter.  The only thing that maybe different is the plug end that goes to the base and the handset adapter, but my bet is they're the same. 

Looks like you can get them at Walmart and on Amazon. Just search for handset charging adapter for DLP7236

Thanks, spoom2.  Walmart and Amazon were a bust (at least I couldn't find it).  The 2nd suggestion helped in verifing that base and handset charging use the same diameter plug, so when I called (on 3rd suggestion), I was able to answer their questions.  Ended up purchasing a handset power adapter.  Now to wait 10-14 days to see if it works.  Thanks again

I'm sure there's several of those online that would work, but I think you were smart to get it from a reliable source that you know will work.
