There was a post on fixya in about December of 2007 detailing the replacement of capacitor C581 on the "D" board but w/o pics. I can't seem to locate that link now.
But... I just did the C581 fix on my set tonight. Here are pics
====Disclaimer==== WARNING! There are high voltages inside the set even when unplugged dueto stored energy in some components. Do not attempt this yourselfunless you are experienced with this type of circuitry. I stronglysuggest that you get a professional repair person to do this work. ================

P.S. 33uF 160V capacitor from www.mouser.com is 82 cents plus shipping in quantity one.
P.P.S Kids are disappointed we aren't going to upgrade to 52" LCD this week.
No you should only transport it standing up to ensure the optics do not get messed up. I have seen peeps do this and nothing happens. I have also seen pros do the move on the back or the sides and it tears up the TV set. Good Luck
I had the same problem soI decided to go ask at our local tv shop Panasonic warranty place and he was nice enough to tell me the problem .
So for everyone reading .. these had a defect with some of the disc
capacitors they used on the CRT board it as 2 on there .
The second problem is with the ``YC`` chip . panasonic sets have many unusuall malfunctions caused by this chip such as a black & white picture or brightness problems . unfortunatly my set has a bad chip .
There we all learned something today . he invites you to contact a
Panasonic ``rep`` he will tell you the same thing .
