There are 3 sensors on the thrust retainer bracket that tell the deck the door is opened, closed and locked. The closed sensors can easily get damaged in the reassembly, its wise to turn the white gear on the far right a little bit to avoid the tab on the gear to land right on top of the sensor. Giving that gear (ejection gear) a turn... It normally point to 6 o'clock, best to turn to 4 or 4:30 to avoid the sensor tab then turning the gear back to 6 o'clock to engage the closed sensor.. once assembled. Great job so far. Personally i would have removed the door and replaced the pinch rollers as well to avoid future wow and flutter. Ill have to share a link with ya to help you with TCM 190 & 200 transports

Thanks for the great video.. Replaced both belts and everything is working fine FF/RW door opens and closes perfect... Display is working perfect after the modification of the ir receiver... The deck will not play. With the top cover off I can see the belt turning the capstan when at idle and when I press play the heads move up but the tape never moves... Please if you could kindly respond with an answer as to why this would happen? Thanks very Much! Ed

Hi, great channel. I wonder if you might have any ideas or pointers on what to look for. I got a TC-K677ES, and on playback, I'm only getting sound from the right channel; the level meters also show no audio on the left channel and only sound from the right. It does this from the headphone and rear line out. If I record to the tape its records both channel in stereo (confirmed this by playing tape in another deck) If I press the monitor button to see the source, I do get both left and right stereo sound output from headphones and line out, and the level metre shows both channels working. Only when I go back to the tape monitor will I have one channel working. I also have hum on the rear, but I think this is because I changed the motor as it was not spinning before, and I have read that some cheap motors have a ground issue and create motor hum. That's a side issue for now. I'm just trying to figure out why, playing a tape, I only hear one channel. Thank your any advice you can give.
