Hi ! I recently bought Teac X7r from someone. The deck is playing well except that the LED lights on Keyboard play, reverse, rec. and Pause are not working. Also while forwarding & reversing both the pullys are trying to pull the tape in opposite direction. Ideally one pully must be free. Apart from this nothing happens when Reverse play mode or Recording button is pressed. It seems that IC AN6251 is defective. Can anyone please help me resolving this issue. I will be really gratefull.
