On the adapter: I've seen them a LOT less expensive just recently. Google it and choose "shopping" to narrow results. There won't be many, but I think you'll find one at better price in just a few minutes. Try ebay as well; that's where I found repair parts for the same model. Good luck!

The only vendor for this would be sharp or a authorized parts dealer. The cost of these LCD panels usually makes the repair senseless. You may get a cost estimate from sharp at 1800-besharp.
I hope this helps,

The DC/DC converter went out on your set. When you take the top off of your AVC box look for a 4" X 5" circuit board mounted on the front left corner. I have seen these fail causing you white screen. Order the part from your local Sharp service center. Part # RDENCA089WJZZ

Not sure if I just got lucky or if the problem is solved..I hooked up my Sharp Aquos LC-32D64U the other night and I had the blue audio box pop up. Mine was only in Mono and would not switch to Stereo...Well, Local cable company is of of Hi-Def boxes but I thought what if my Digital box is bad/old or has some sort of problem. I went down to comcast cable company switched to a different digitial box..came home, hooked it up and so far no blue audio box, plus now it shows that it's in stereo..good luck
