You sure you changed C57 too?

[darko]

I change C56, C57, C50,C48,C40, C45,C46,C42 but lines are still here

You either have a magnetic source on the left of the tube, or the caps you used were bad.

you changed every single electrolitic on the entire chassis including the neck card?

[darko]

No, but I change the electrolitic capacitor on the neck card. But lines are still here.

There are 17 electrolytic capacitors you need to replace on this monitor.

[grantspain]

you need to change all the caps in the power supply circuit,i have had the same fault on hantarex polo's and you cannot narrow it down to one cap,you have to change all

I change C56, C57, C50,C48,C40, C45,C46,C42 but lines are still here
