Information regarding Samsung pdp please.

Hi All, I`m fault finding my ps50c96hdx and am trying to establish if the display has failed which is likely.
i`m certain after testing that both upper and lower buffers have at least one ic dead although there is no visible damage . My question is that with the y-sus board removed and then powering up the tv i can measure voltages on the y buffers that must be supplied by the panel itself as far as i can see. this is not stored power being discharged it is definately a supply voltage from somewhere and as they are now connected only to the panel , that is the source. Does this either confirm or otherwise the viability of the panel?
  I hope somebody can shed some light on this for me please.
   Many Thanks   Dave in a rather drizzly Cornwall.
