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 farLast edited by bikerbuddy; 01-07-2021, 11:11 AM.

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.Last edited by dick_barton; 01-07-2021, 11:34 AM.Willing to help but I'm no expert.
