TV is LG 42PC3RVI found burned module LGEPDP 060908...fuse FS1 burned and hybrid IC2 was in short. Voltage Vs=188 V and Va=60 V...OK.
I changed all module but immidatly after replacment and switching on hybrid IC was burned again !!!
I measured resistance beetween SUS electrode and the chassis-but it doesn't show any short. Resistance is very high.
Is it mean PDP is faulty?
If the buffer drive bds. were replaced along with the ysus and zsus and this problem occured it is definately and defective pdp.

This is an indication that you have a short on the power supply section.
It can't be fixed by replacing the fuse alone. I've suspected that you have a short on the following parts :

2.Rectifier diode
3.Main filter electrolytic capacitor
4.Voltage regulator I.C.
This is the common parts that might be shorted and made the fuse blew. #2-4 is quite technical and need an expert to do the job so I
