Va voltage is 65v and Vs is 187v all other voltages are present from the power supply that supply the various boards , how can i tell if the IPM is bad or which one ....

by r-pStarting this thread because Capkid doesn't seem to be reprogramming controlboards anymore (LG 60PZ950 with red maldischarge) and my game-plasma also has maldischarge (Hitachi 42PD3200). So I will grasp at straws to keep them running. I am extremely bad at throwing stuff away.
Is there any merit to this link?
Very short version: Specific caps seem to loose their capacitance and/or increase their ESR. This may cause the maldischarge. Replace them with better/bigger/newer ones and problem solved.

by ArMaaN376Hello,
I am having Samsung PS51E550 Plasma TV. While the TV was working, a crackling sound heard & video went off with audio still ON. After switching it off & ON, the red LED on TV blinks six times & then off.
Opened TV cover & observed foll
a) Green LED on the small PCB blinks at @5-6sec ON & off for 3-4 secs. Red LED on logic board ON
b)Vs & Va on power supply board raises momentarily to 209v & 58v resp & then drops.
c) Cold test on Y-main board shows all 3 pins of FGPF4536 IGBT short to Grnd.
