The manual refers to a Sony YEDS-7 test CD is it necessary? it seems like its a bit tricky to hunt down. Will any cd work? Crosstalk is generally tilt I believe, should be able to do it with trial and error and no scope.

Just need to await the service remote!

If you do not have disc then you must take your chance and hope you make the correct adjustments for all.
Sometimes you can adjust to make this work but that won't now or anymore so then you are adjusting all the time. If you ask the experts they will tell you how to adjust tilt and it isn't with a test disc and a scope, it's with a small adjustments and a movie playing.

I had a player that didn't play one disc once, I adjusted the focus to play that disc and then it wouldn't play many other discs that it did in the past. Luckily I kept note of where it was and put it back so I only had 1 disc that didn't play out of 400.
I guess my mistake was not owning Goldeneye. I still don't know what your issue is with me? You are talking focus I am talking tilt, these are obviously two very different things.

You cannot take your bad experience guessing on FOCUS and apply it to TILT they are two completely different adjustments. I've also told you that I know this not only from personal experience but also from being told by Kurtis Bahr in person. Apparently this is not enough for you though so whatever I guess no point in trying to help anyone here.....

Check your FB PM, you don't need service remote or test disc, this dude has a personal ax to grind with me for some unknown reason.

The real issue is that while you can adjust stuff doing it one way, the way to get it exact is by doing it with test discs and specs. Is this the only way, no, but its the best way. If you don't have the test disc and scope you can always use Goldeneye.

The manual refers to a Sony YEDS-7 test CD is it necessary? it seems like its a bit tricky to hunt down. Will any cd work? If you've already "fiddled with it" then depending on what you did I'm thinking there's a good chance more than just one thing might need setting back correctly?? If so having a scope and running through the alignment procedure in the service manual might be a good idea just to check everything over? (Well at least the adjustment for any pot you fiddled with anyway.) I'm not expert on this but as far as I know, where the test CD is called for that a standard audio CD will work for those adjustments in the alignment procedure (proper pressed one not burnt).

I'm not expert on this but as far as I know, where the test CD is called for that a standard audio CD will work for those adjustments in the alignment procedure (proper pressed one not burnt). Yep I fiddled with the tilt while connected to a DVR -> DVDO -> Projector I don't think that is the ideal chain to fix crosstalk Yesterday I Hooked it up to a CRT, centered the tilt adjustment pot for side A and side B Then I played a disc and adjusted tilt slightly for side A and the image is perfect when it comes to crosstalk I got side B better but not perfect. It's as if adjusting the tilt for side B would need another quarter turn. So the eager me probably did touch the wrong pot at some point during my first fiddle-session a couple of months ago. So after the holidays I'll have to schlepp the LD player to my friends house and use his scope. I used the pioneer test disc and a CLV criterion with color bars to do the adjustments. The color bars are usually at the very end of the disc where CLV crosstalk was at its worst. I ran the same test disc on my 950 single sided player with zero crosstalk.

Correct CRTs are the best to do your adjustments. All the techs use a 13 inch as it works just fine for adjustments. Good luck on getting it back to working
