Epson SureColor T7000 Clogged Cyan & Yellow

[Isaac11]

Hello Guys,
I have a 2 years old SC-T7000 and now I have some problem with printing.
Check my Nozzle Check.
I have done anything (AIS Fluid, Cleanning the wiper Blade but didn't find the way to remove it..., CL1 CL2)
Last question regarding my capping station do you think it's normal to have some silver line inside the blue row ?
Do you thing on the Cyan Pattern show that my head is dead ? And there is nothing to do except buy another one ?

Sorry for my bad english I'm french..

Thanks in advance
