Hi,

I feel like a dork for asking but after exhaustive investigation, I
cannot figure out how to adjust the vertical hold on my Quasar SP-2725
television.  I believe it is manufactured by Panasonic.  Thanks.

Hello,

Don't feel like a dork!  Everyone loses their TV manuals eventually! 

You're correct, your Quasar SP-2725 is made by Panasonic.  They're
usually pretty good about keeping manuals online, but they don't seem
to have yours readily accessible.

Here's how you can reach them:

800-211-7262

E-mail: ConsumerProducts@panasonic.com

Hours of Operation:
Monday – Friday 9 a.m. – 9 p.m. EST
Saturday & Sunday 10 a.m. – 7 p.m. EST
Open on Holidays 

(Posting as a comment because Panasonic is closed at the moment.)

Hope this helps you straighten things out!
