Today I am pleased to report I have completed my first GS 1200 repair done by myself. It was a minor adjustment. But still, on these machines, any type of fixing requires patience, knowledge, and skill.
The other night I started an optical feature, and the sound was just terrible. There was intermittent rumble in the background. The treble was gone. The sound was very mushy and also lacked bass.
Upon examining the projector while running, I found the film was moving up and down in the bottom right green guide just before the slit lens and exciter bulb. It would move up and be tight and it would move down into the deeper part of the green guide.
I checked two other machines, and spotted the tension spring position was different. In the two checked machines, the spring clip was pointing slightly to the left, at say 7 O’clock position.
At the machine giving trouble, that same spring clip was pointing straight down, as 6 O’clock position.
This morning, I carefully loosened the retaining screw, and gently moved the spring clip to the 7pm position. A quick test of optical sound and BINGO sound is where it should be.
I like running these things but I am not much of a technician.
Except for this one time I guess. Shame to have taken it to a repair $hop just for this one speedbump………………
Feeling a tad bit proud!
