Title: TG16 CD-Rom pot default values
Post by: waynedoodle on December 20, 2014, 05:13:06 AM: I'm replacing my middle gear this weekend. However, over a year ago I moved the pots trying to fix the cd-rom before I was able to ID the broken middle gear.

Can someone help me with the default values or a screen shot? Hopefully I won't have to replace the laser.

Thanks!

David

I've seen some that have been slightly different than others and have never been tampered with. Anyways, this picture will at least give you a rough ball park. (http://pic.photobucket.com/bwe.png)

But, the audio cd I tested sounded poor on the first track. Using the pic above from right to left, which one should I adjust first? The cd player found all 14 tracks but would not play correctly.

Pardon my ignorance, I have very little electrical knowledge on this DIY project other than this board and 2 youtube videos to go by. Searching this forum gave little hits on my search.

This cd-rom has not been used since 1996 in my dorm room!

Cheers!

Usually the two black pots that are right next to one another are the ones to adjust. The white ones hardly ever need to be adjusted.

I had to move the pot on the same side of the laser 1/8 of a turn and it stopped skipping audio tracks. Probably need to add some more grease to the track mech.

My brother and I got the TG16 CD for Christmas in 1992. Wow; we are getting old!

Good to hear! Congratulations! Mine was dead about 10 years before I managed to fix it (with the help of PCEFX). Its a good feeling...
