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

Here`s a quick ME Firmware cleaning guide.
The guide is basic,its main goal is to show you how to use intel FIT,its highly recommended that you all follow the guide posted at win-raid
(The attached FIT version is 11, if your ME Firmware (FW) is not 11.0.*.* follow the win-raid guide. Use the tools version for your ME FW, for example: ME System Tools v9.1 For systems running ME v9.0 - v9.1)
A video,software (intel FIT) and practice bios are all included. I`ll post a better video and more advanced guide at a later date.

Hey,
A month back I replaced the selector switch IC on my Panasonic SA-HD52 as the radio was still playing when I selected the CD, it did this with the tape and record too.
Now when I replaced the IC it worked perfectly, no cross talking and I left it at that for a month and have come to it today to play a CD (you can hear it spinning) and the issue has come back although with another issue.
Both issues are random, the original problem where the radio will play over other playbacks has come back and another time you turn it on it will refuse to play anything,...09-07-2025, 07:23 AM -

This 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... -
