In reply to Prahlad. It appears that the power button may be faulty. Try short circuiting it and check. Let me know for further development, here only.

Hi sir I have a raagini digital which only has one knob. It does not turn on. I have opened it up and see a red light on the PCB. There is also current flowing to the touch board. But I am not able to turn it on when I tap the power button

In reply to Manish Parikh. If you have read this comment, then it was for different module. Do not use 12V adaptor, if you have an old model.

My 15 years old model has stopped working after accidentally connecting mains to 110v socket instead of 220 as required here in Bangalore India..what could have possibly gone wrong? Replacing the transformer may help?

In reply to Surendra Mujumdar. Respected Prof. Mujumdar, Actually the working circuit diagram of the SMPS of Ragini Digital Tanpura is not available. The Ragini designers have changed the circuit almost 13 times within last 2 years. So I don't know if at all the circuit will be any of use to you... Since your tanpura is working on 12V adapter, I will suggest you to continue with it as much as possible. Because the company has such a monopoly in the product that they change the thing quite randomly that you can not continue with its pace. Rest assured, please continue with your beautiful modification. I will also include your modification details in my next article on Ragini Digital Tanpura on my website.

Hello Sir, I am Prof. Mujumdar (Retired from an Engineering College from EXTC dept.) My ragini tanpura is shutting down after a few minutes. So I removed the SMPS and replaced it with a 12 V adaptor. Now it is working fine. Since I don't have the circuit diagram for the SMPS,I am wondering if you can suggest which component from SMPS is getting heated and shutting it it down.

In reply to Sunil. The solution to your problem is quite simple. Open the lid of the tanpura and remove the variable resistor which works as volume and on/off button. Connect DMM in Ohm mode, across any two adjacent terminals of variable resistor. Now rotate the variable resistor, you will see that its resistance does not vary smoothly. Check the value of the variable resistor at its back side. Purchase new one and connect it inside the tanpura.
