Well, then I stand corrected. Sounds like it's trying to boot up but can't find a bootable ROM image because the one on board has been corrupted.
If indeed it's WM8505, the Sylvania netbook ROM will work. Go to H/PC:Update and select "Sylvania" as the device manufacturer and "Wireless Smartbook CE6" as the device, and then click on the "Go" button.

Click on "ROM Updates" and then on the plus sign in the download description to place it in your download cart. Once you've downloaded it, copy the "script" folder to an empty SD card and place the card in the device while it's shut down. Then power it on and it'll install the ROM image automatically.
