Can you post a photo of the white label that gives the voltages located at the top of the panel.

Are all the voltages as per the label?

Va & Vsc are per the label
how about the others:-
Vy, Vsc & Zbias

Yes just verified that these voltage Va = 65v , Vs = 187v , Vsc = 85.9 Vy = 85.9 where can I measure voltage for Zbias.Thanks for your help so far

Re: Zenith plasma Z42PX2D 12 flashing green

I think Vsc according to the label should be 115V and Vy = -85V
I did a search on the forum for IPM and several threads came up using your panel with some information relating to the voltages required.
My Knowledge of plasma sets is not that good but there are some members of this site with better knowledge than me who I know would assist.

I just found this info on a PDP 42v7 module service manual should I adjust the
Vsc to 115v and see what will happen ?
