    Re: Help identify boards in Samsung plasma

    Jumpered VS_On with 5.3V. All voltages (Vs, Va, Vsc, and Ve) come up and stay up. Va still only reaches 50-52v, and Vs keeps climbing past 240v. No picture -- only flashes white noise once as shown in the photo above.

    I've changed pretty much every board in this unit except for the main board. It's probably worth noting that if I put the old X/Y Main and Y-Buffer back in, I do not get the picture flicker at startup.

      Tom -- you think those dark spots in the screen flicker might indicate the panel itself has failed?
