Visio M550NV no-boot

[miniman82]

I got in good with the local e-waste guy, says I can take flat panels from the pile and he won't know who I am. lol

So I grab the biggest one I can find, and at first when I plug the thing in the logo alternates from white to yellow indicating a problem. So I pop off the back and check the power supply, which is actually good. I stimulate the power on terminal by jumpering 5v to the power on pin and the backlight springs to life confirming the screen isn't shattered, but there's nothing actually on screen. Laid it down and I can hear what sounds like a sizzle coming from an enclosed metal box on the main board which I believe contains the main processor, can't troubleshoot that so I look for one online. $150! Does anyone know of any tricks to repair this board, or am I down to scavenging one from another set?

Need a new jog board too, the connector is broken.
