Because i have had several motherboards for repair which in my case just works, but not by the owner I noticed that it is not always a fault on the motherboard, but most likely due the front panel. As far as I'm looking at, the motherboard dc/dc converters are switched on separately from the front panel. Most likely with a ic from the panel. By making a few bridges on the connector, they can be activated without the use of the front panel. Every connection is to switch on a dc to dc converter, missing one connection results of disabling one dc converter. For example you may have a red led issue and thinking that it's related to the software while it's actually caused due a issue with the front panel, or connection from it. Same as you may see in a rs232 terminal output screen with only a code 73460012 which I noticed it were related to a inactive 1.5v on the motherboard. When I used this jumper plug the motherboard just worked. In any case, this information may help you to find the problem but best is to first measure the main dc/dc converter outputs to see if there is something wrong with it. If so, then it may be handy to make this jumper connector to see if it's related to the front panel. However at this moment I do not know the push button pin, so it's not usable to flash the box. Maybe, if I have found it, I will add it to the picture. But it's for me hard to find at this moment due the leak of owning the solo2 front panel, I only have the motherboards.
