Re: ISE W1706W – won’t turn on

Hi Dave,
The second board has a STM8S207 microcontroller chip plus a couple of other chips.

drops to zero with the cables unplugged

Re: ISE W1706W – won’t turn on

Apologies for the confusion.

I’m getting about 1.1v across one of the black capacitors (fluctuates slightly but only about 0.03v or so)

Re: ISE W1706W – won’t turn on

Thanks again. Point taken re the high voltage!

The thing that I’d thought was a voltage regulator turns out to be a Triac – I’ve only just been able to identify the part number on it. I can’t see anything else that looks like a 3-pin regulator – images attached in case I’ve missed something blindingly obvious.

I’m thinking now that it’s got to be a new control module (£190) or a replacement machine. Do you think there’s much of a risk that the new module will not fix the problem?

Cheers,
Martin

Hi Dave,

Many thanks for the speedy response.

There’s no sign of damage on that other chip. Presumably I should look for 5v or so across 2 of the pins on that chip?
