Jamie867 after our last correspondance I began to pull the power supply assembly. I then noticed another bank of fuses and found a 5A/125V (Pioneer part number FU206 per the circuit board) fast burning fuse was burned out. I went to Radio Shack and purchased a bag of the 5A fuses and had the fuse (FU101 10A/250V) tested that I could not see through yesterday and it checked out as good.
I replaced the burned fused and reconnected the power cord but the fuse quickly turned red and burned out (I did this twice and then unplugged everything).
Per the partial service manual I purchased yesterday (did not realize there were 2 parts to the manual) I noted this fuse is part of the Power Supply Assembly (Pioneer part number AWV1710).
Per the pioneer site the power assembly is in stock. I am inclined to replace instead of repair at this juncture. However, before I order a $352 part I want to make sure that is the appropriate course of action, i.e. I don't know if that fuse could blow from a problem in another area/board.
Your recommendations are appreciated. I would be glad to email the Service Manual I have if that helps, it is in a PDF file.
I had an issue with my PRO-700HD: The main power would come on fine, however when i would power on the standby power, it would click on, the light would turn green, and then it would turn off again a second later.
I called a service tech, and they repaired it. I asked whether or not it was the power assembly, and they said no, it was the convergance circuit. They were here for about an hour, one person doing something with a drill behind the TV, the other was soldering a circuit board they had pulled out.
a 6ya Technician can help you resolve that issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repair professionals here in the US. click here to Talk to a Technician (only for users in the US for now) and get all the help you need. Goodluck!

Plasma and LCD TV sets are prone to having capacitors in the power supply section fail. This is the most likely cause for the probem you describe. When capacitors fail your will commonly see one or more of the following symptoms.

Thanks for trying… partstore.com was actually the website that I originally tried ordering from. I feel lame for not including that tidbit of info on my original post because I didn't want to give that site a bad rap. After a bit more reasearch I discovered this site: http://www.highreflectivemirrors.com/ they carry the replacement for only $120 with free shipping and with only a few clicks I purchased it via PayPal. I am currently awaiting delivery and will post again if for some reason it doesn't work out.
The failure is not on the power supply but the convergence amplifiers STKICs have the 24 volts shorted.
If that fuse is blowing, de-solder the convergence ICs and put a new fuse to power up the TV; you should see distorted video when the TV powers up and the fuse should not blow.
The service manual migth not help much in this case since the failure is easy to pin point.
