Is there a reset button or a fuse on the stanton m 203 mixers ive lost power

The problem is likely in the power supply. I recommend taking into a repair shop.as it is not a user servicable problem.

Pilot lights mean very little. Either a filter capacitor failed or other part(s) failed. Needs to go to the repair shop. The damage MAY be visible or require test equipment to diagnose.

Transformers are VERY reliable. Look for another problem... rectifier, filter caps, fuses, regulators. There is a main fuse and if it is blown, repair the unit before applying full power. To test the unit, put a 40 watt light bulb in series with the hot side of the power cord. The light will act as a resetable fuse and will light when there is a short within the mixer, thus absorbing most of the voltage. Enough current will flow to diagnose the problem.

Why did you change the fuse? If it was blown, then power supply has failed. Here is your schematic. The power supply is on page 14.

Scroll down the page at the site to the "Get Manual" Click on that to download the schematic. When working on line operated supplies use an isolation transformer for personal safety. The regulator chip IC2 has probably failed but test before changing. HINT: When restoring the supply, put a 60 watt light bulb in series with the hot power lead to act as a resetable fuse... saves fuses and also other components if all the bad parts haven't been weeded out.

You need to REPAIR the cause of it blowing before you worry about what size it is. Replacing it without repairing MAY damage additional components.

For 220 Volt service it appears to be 250ma for 120 it appears to be 400ma

Here is service manual:

Good luck..

After reviewing the schematic, I don't understand how the Phantom power can REMAIN on with the power switch off... this CANNOT occur except for what energy is left in the 48 volt supply filter cap... This might last for minutes after the fuse went... UNLESS you have devices connected which are backfeeding the 48 volts. (which would be a disaster)

The 48 volts, +/- 12 volts and +/- 15 volts and the +5 volts ALL come from the SAME switching power supply. I suspect one of the filter caps went or the primary switching regulator a TDP245Y chip.

You should ONLY work on the line side of this using an ISOLATION transformer since the line side has lethal voltages.

To do testing, one replaces the fuse and puts a 60 Watt light bulb in series with the hot side of the inout line. The lamp "acts" as a resetable fuse and limits the current for testing. When all is well again, the lamp will remain out with the power flowing through it.

The D1 diode bridge and C7 input rectifier and filter are first things to check. You can do those with an ohmmeter.

I will caution you to ALWAYS power any and all equipment from the SAME power source. Plugging in devices from across the room will set up ground loops and any ground fault will fry equipment.

If it is brand new, it is likely "pilot error" as setting these up if you are unfamiliar with mixers can be frustrating.

There are several things that must be done to have a working system. Correct speaker cables are one and the setting of all the knobs are important...

DO NOT REPLACE FUSE. If any LED's are on, fuse is OK. If fuse blows, service the unit before replacing fuse to avoid further internal damage.

Make sure speaker cables are good.

Set the level control for the channel you are testing up AND you may need to press the "PAD" button to change the input gain. Turn up the master gain.

Depending on the source you are using, line or mic you may need to change the PAD button.

NOTE: This mixer does NOT have Phantom power and cannot be used with CONDENSER microphones requiring phantom power. You will get no audio from a condenser mic without phantom power. You must use dynamic mics with this mixer.

Most likely the fuse for the effects circuit has blown, which happens sometimes on mixers with built in effects.

You'll have to open the mixer as the fuse will be inside the mixer on a circuit board (look around inside where the effects part of the mixer is) replace it with an identically rated working fuse and you should be done.
