I have problem with NX6110. When you plug

I have problem with NX6110. When you plug in power charger, voltage on power connector drops to 0.15V and going up to 0.9V and then drops to 0.15v...
Nothing is heating up. I changed C57 with no result. Just one of front panell led diodes is blinking.
Did someone had similar problem? Maybe FW82801FBM?
