MP710086 change input voltage from 110V to 240V

The image is quite clear for me. Maybe some issue with quality when uploaded here. 

The D panel is for RS232 communication programming/control through SCPI commands I guess. It also communicates via USB. I checked the website as well, they clearly have two different models of the project one for 110V AC and another for 230 V AC

True. Even I was surprised. The sticker on the back save me, otherwise I would have plugged it in directly.

What is more shocking is the there were 2 winners of the grand prize and both are in South Asia and we have 230V AC supply. 

Unfortunately, the power supply transformer doesn't have any label. But other products do have a label on the transformer.

No, the transformer is specifically designed for 110V AC input. The power supply has a toroidal transformer with no specs written on it. 

For example- I opened up the soldering station and this is what is written on the transformer.
All these units also come with US plugs. I have modular socket at my home so plugs are not an issue but the operating voltage is. 

The transformer takes 110V AC, steps down to 24V AC for the soldering iron and 9V AC for the PCB Panel with LCD. There is a small bridge rectifier near the 9V connector. 

I'm thinking, if I can simply replace this transformer with a 240V AC to 24V AC at least the soldering iron will work and I will bypass the AC connector and connect 9VDC supply to the panel. 

                

Looks like the only task is to change the fuse:

You could use an external 2:1 step-down auto-transformer to provide 110V AC to the PSU from your 240V AC mains supply. They have a tendency to hum slightly and the regulation isn't too good on the smaller ones. On the up side you don't need to make any changes to the PSU, so it won't affect any guarantees or warranties. The main problem with supplying an answer to this particular problem is that the photograph of the back panel is slightly blurred which makes all the legends and labels difficult to read to say the least. I don't know what the 9-way 'D' connector is for, nor do I know what the rectangular connector underneath the ratings table is for, the one that looks like an old-fashioned printer input socket. A close-up clear photo of the ratings table would be very useful, as would one of all the wording above and to the right of the yellow 'danger' label.

Still puzzles me how the Avnet companies keep on keeping on making that mistake. While international sales of electronics is the core business. I tend to get devices with a US plug.

was there any numbers on the transformer

could you identify the primary wires 

do you have photos of top and bottom of board 

Yes, the hot air rework station is high power (1kW hot air gun).
Other prizes are fine. Only the three I mentioned above have the voltage issue.

I already have a Keysight triple output programmable power supply so anyway this would been a secondary supply. 

But I don't have a rework station. I think I can still make the soldering station part work with a low power voltage converter as it comes separately in the rework station. 

The hot air rework station will require a large transformer : (

Not sure of a solution, unless the heating element can be replaced, which may cause all sorts of other complications if the rest of the unit isn't designed for that.

I'm hoping most of your prizes can be switched to  240V and it's just these ones you've listed that have the issue?
