BIGMAN:
RZ42px11 [42"Plasma] Have vertical colour lines over entire screen like a rainbow. Sound and everything
else seems to be ok.Does this fault sets anyone thinking? Please let me know something no mater how
small thanks BIGMAN.

tv tony:
disconnect lower drive pcb. if then u get upper pic it proves it, very common

BC109:
Yes sounds like what Tony is saying. Lower YDRV board faulty. It's also recommended to replace YSUS as well.

mike pritchard:
After replaceing driver boards you may get away with soldering joints in Y sus instead of replaceing it

BC109:
mike pritchard, thats interesting. Which parts dry joint?
I've only ever replaced YSUS, if you dont YDRV will fail again.
