i have the same problem with a broken PSU. In germany they stopped the repair service. I've tried to contact atrc.co.kr (perhaps they have closed the company because the atec europe is closed too) - no answer. I've tried to contact ipt.co.kr (they produce the PSU) - mail does not work.
Pleas TV-Tony contact me - or if anybody has a circuit diagram of the psu would help.
Does anybody had succes in repair this PSU?
Thank you
