In this video, I identify with a volt meter the RI signal in order to detect the chip that is defective. I then take care of unsoldering it and prepare the base to receive a new chip.

I hope you will enjoy this video despite the quality (format error at the recording the next ones will have another camera)In this video, I identify with a volt meter the RI signal in order to detect the chip that is defective.
