For repairs in Europe : www.pcpraha.cz -- there they have service. In Czechia. I can confirm that. Here is link https://pcpraha.cz/en/produkt/oprava-antminer-ks5-pro-al1-s21-t21-l7-l9/?wmc-currency=EUR/
There at pcpraha.cz -- shipping cost about 10 USD there, repair from 50 USD. depending of faults. If not feasible or economical to repair they return free of charge.
Also oneminers can repair ASIC miners here https://oneminers.com/pages/asic-miner-repair So you can check here.
Basically you are mostly paying for burned chips and the number of burned chips influence price estimate and final price.
Repair time varies from few hours to days. BTW: yes they can repair whole palette of ASIC miners in week.
These I can truly recommend and I would put hand to the fire for that.
