I unfortunately have a Duo that will not power up , and i am lost to whats up with it, everything looks good it is getting power, i gave to a friend who says that "about the pcb engine duo i have checked for short circuits. there is one on the power line but i cant find the component causing it. all the ics are connected to the power line. any one of them could be causing the short circuit"
anybody have any advice on where to start ?
thanks in advance

There are also many capacitors which bridge between ground and power. They shouldn’t actually cause a short circuit, but when certain types fail, it is possible. If it hasn’t already had a capacitor replacement during its lifetime, it is due for one. If a full capacitor replacement is being performed anyway, removing them will narrow the problem set, even if they aren’t the direct cause. But first, you should be clear that power is actually being consumed… there is a fuse which can blow, causing no function. Other approaches I’ve heard include using a current-controlled power supply and a FLIR temperature imager (parts which short will get hot).
But this is probably not the best way to learn… I would suggest sending it to somebody who does these repairs regularly.

Well, I'm not in the UK, and I don't know a lot of console repair shops, but here's an idea: - Take a look at a seller of a modern retro device - Search for a "recommended installers" list by region - Ask if they do repair service In case you don't hear about personal experience from somebody here, I would suggest that this might be the next best option; at least they're trusted by people who make delicate equipment. And in some cases, these modders might have other hardware or services you might wish to check out. For example, this page has several UK-based installers who also do repairs (halfway down the page, under "recommended installers" - most of them have direct links to the corresponding websites): www.black-dog.tech/ps1digital.html
