Quoted from dgasek:Please look at picture below - it looks someone before me connected pins in wrong place. Power is connected between pins 4 and 7 , so it means is connected for 206V . Am I right ?
You said it was working before so why would you suspect these pins are "connected in the wrong place"?...unless someone else has just been working on your machine there is no reason to suspect anything was changed. You are likely hunting for a component failure. Start with disconnecting the transformer and making sure the turning on the switch does not trip the breaker. If it doesn't the problem will be further upstream. Divide and conquer.
