Re: Soundcraft DCP100 PSU
Post some nice straight shot, high resolution pictures, so we can see something. Also describe exactly what is or is not happening, like blowing fuses, no output, wrong output etc. Some voltage rails working, others not, etc.
By looking at the PSU there should be 3 voltage rails. +15V, -15V and 48V phantom power.
I found a schematic for the Soundcraft 200b. That should give you a guide line on what to expect. It won't be the same, but it should be similar.

Re: Soundcraft DCP100 PSU
As its a conventional linear supply with mains transformer, i would connect a multimeter in ohms mode across the live and neutral power input, you should see a resistance.
If not then check the power switch/voltage selector switch and input fuse.
If the voltage selector switch is in the wrong position the primary winding of the transformer could be toast :-(Comment

by acedogblastThis is a guide that I am writing for helping others to replace their MEC1503 EC chip if it breaks (or to get around an inconvenient prompt to the BIOS). This forum has been extremely helpful to me so I would like to contribute to help others. I will tell you right now that this task is very difficult to do. You MUST have experience and tools to do precision micro-soldering, BGA reballing, trace repair, and general laptop repair skills.
There are some specialty tools needed to do this task. The replacement MEC1503 chips can be acquired from Aliexpress. Do not buy the bare chips as... -
