I've been getting quite high error rates from the dolby digital reader on my Kinoton FP30 with a CP500. Brand new trailers will run at 6 at the very lowest. Most digital tracks will be at 7 with the majority of older prints running at F.

I've searched on the forum and I notice that the video level is important. Could this be the problem? If so, how can I adjust it? I am handy with a scope, but I need to know how and what to adjust and where to measure.

How old is the LED? I'd start there.

I don't know your skill level but in my experience if you have to ask this question, you probably shouldn't mess with it but rather get a tech. Any number of things could go wrong if you're not experienced with the unit in question.

Agreed with Dominic. The outstanding odds are anything you do to the machine will only make it worse.

It is time to call in your tech.

If your CP500 is on 24 hours a day,it may help a tad to power it down ,off and then back on. I found they go into a fog if on constantly.

How old is the LED? Might just need a little gain adjust... but a tech is probably best.

As regards the age of the LED, I'm not too sure. I obtained the projector recently and I know it was manufactured in 2001/2 so at the most, it's ten years old. As I'm just using this in a home screening room, I was hoping to adjust it myself but after reading the good advice above, I've got the number of a local tech!

If it's for your screening room, then there is really nothing to lose by doing the alignment yourself. Worst case, you need the tech anyway. Best case, you might learn something and save money. Since it isn't a commercial theatre, you don't have the concern about losing shows.

Everything you need to know is in the CP500 or DA20 manual.

The Kinoton readers are at least as good as the Dolby penthouse readers, if not better. I have never done the alignment on these, but have operated several well-maintained booths that have them. You should have no problem getting 2s and 3s on most prints (and even the occasional 0s and 1s) if everything is set up correctly.

You could try turning up the wick on it first although I've had more success doing this with the system faulting. I doubt turning it up is going to get you a much better error rate if any better at all.

There should be two pots in the back of the machine, one for analogue and one for digital.

Does this projector have the O-rings on the edges of the lay down roller? They may be worn out. The latest ones are green not black.

The rings seem to be green ones and they look to be in good condition.
