Re: Sony STR-DB940 pulled back from the brink
You need to inspect the joints carefully, or just reflow the lot in that area.
Take a careful look at the joints in the center of the attached photo, from my STR-DE545.
You should be able to see the cracks around the joints, halfway up. I reflowed all which looked suspicious, adding a touch more solder to each one to give some fresh flux. Most were around the main power ICs which generate a fair bit of heat. If that does not fix it, you may have a faulty component instead.
