Question about LG 42PC3DV 42 in. Plasma EDTV
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.

3.Main filter electrolytic capacitor
4.Voltage regulator I.C.
