Re: yamaha CS-10 stuck LFO!

Hello,
I have come across a similar problem with my cs-15. I was adjusting the VR's for the LFO speed and somehow the sine wave died during the process. The other waveforms are fine. Now, when switched to sine wave the LED is not working, nor is the LFO sine wave. The LED works as it should when in the Sawtooth and S&H position.

I suspect the IC IG00150 needs replacing, but thought I would research it a bit first.

Any ideas of another possibility?

Thanks for reading. I love my CS-15 and it's my main synth. I can get by without the sine wave, but it is nice to have.
