Sterling Pro Power Sb 600w Inverter Problem.

[Widge]

Hi
I have won a STERLING ProPower SB inverter that is faulty, it was a friends and he bought a replacement and gave it to me to fix or throw away.
It powers up and shows the battery voltage, but no AC output. Here is a video of the startup.

I have emailed Sterling but shipping back from France is now expensive, and although I haven't had a quote yet, i believe repairs are expensive.

I do have an electronics background although not with this type of electronics, I have looked inside and there is no obvious cause of the fault, but happy to have a go at fixing it if i could at least get more info or circuit diagram.

I have searched and the only thing I have found is a youtube video of sombody replacing the internal fuses after a wrong polarity connection. Which isnt much help.

I wondered if anyone here has any experience or tips.

Thanks in advance.
Dave

We had the same with ours, our electronics friend fixed it with no guarantees he fiddled on the first attempt changing various capacitors and in the end traced it to a small circuit board that he couldn't do much with, so basically cooked all the soldered joints on it and hey presto all is good at the moment.
