I am looking for the schematics for p-3010D DC power supply. In this, there is no voltage changes when changing the voltage.
If anyone know the solution about this help me to repair this power supply.

 

I can try when my time permits
Show me some pictures
Cannot find a schema yet.
Have to rely on experience and expertise

NO, I didn't get it yet

The problem is when rotating the potentiometer can't get any changes in voltage and also that doesn't display it.

 

Take some pictures of the PCB so we know what to show you to check.
Mostly it's a simple problem.

 

Now the Display is working but the voltage is not changing and also while checking the voltage with multimeter there is a small milli volte and that's potentials are inverted

 

OK
1. What experience do you have in soldering and DC voltage measuring?
2. What is the value displayed on the front panels at power ON?
3. Need a better pic from the both side of the PCB. I have to deal with photos, so you need to help me here to show what I need.

 

1. I have enough knowledge for this
2.0.3V
3.Insoldering side bottom left side has that big capacitor

 

1. Check what regulators it has on board like 7812, 7805 of sorts.
2. What are the IC's no.s it has, including power transistors
3. If you can power up, do it and check big cap voltage.
Post the findings
