I got into trouble connecting 230v to my 110v dvl909. of course it died. What value is the resistor R102? I'm measuring mega ohms on it and don't know if that's right. Should I replace Q101 even though the multimeter shows it's ok? The card is called VWR1286-A. The main fuse is ok. Nothing looks burnt or damaged.

D105 is dead, so that one needs a replacement. I got informed that Bi-directional diode will work ?

Replaced the D105 to a new bi-directinal one, and the board works as intended now. Afterall it acts like an extra fuse to protect the more vital parts on the board. All pins on cn202 shows exactly as the chematic.

The R102, right next to the powercord input, is more likely good as well. It measures over 3 mega ohms, but works as a "bleeder" to make sure you can unplug the powercord without gettin buzzed....or something like that.

So all in all; Case closed.
