Can anyone help please?

This is not strictly an in car electronics issue, but the circuit boars looks similar in style (bit not size) to the ECUs on a couple of my cars. I’m not sure where to post this thread so I will try here.

We live on a remote farm with our house and other buildings being heated by a 10year old biomass boiler system.

We’re being told that our control panel needs replacing and that it is no longer available as many of the components are now obsolete.

A whole new control panel is likely to cost several grand and there is no idea of how long delivery might be.

I live in East Anglia and wondered if there was anywhere trusted to take the motherboards that I have removed?

We have no heating and no hot water and my family is not very impressed. Any suggestions very, very welcome! I attach some photos to give you some idea of what we’re dealing with.

What's actually wrong with the control panel?

That's a lot of chips. If the issue is one of them, it's going to take more than a hobbyist electronic expert to find it.

Might be lucky and its one of the discrete components - a thorough visual inspection with a magnifying glass, looking for dry solder joints, leaking caps, burns etc is a good start.

Or you might be really really lucky and replacing the battery top left helps

I'm not a qualified electrician. Mains electrics, proceed with caution etc. Even unplugged, those big brown caps top right can be nasty.

None of the capacitors look bulged, which is good.

Are those burn marks on the lower right, where there appear to components on the underside?

I would check/replace that fuse and change the batteries before going any further.
