Greetings,

Bill Walsh here. I'm new to the list, hope I can bring something to the forum other then my problems.

I picked up a Sankyo 600 Sound at the flea market today and noticed that when projecting that the illumination across the screen is not the same, (see image). The right side has fall off and the black line running vertical. Any ideas what is causing this?

Also I don't have a manual for this. Anyone know how to remove the lens and also can the lens be replaced with something brighter.

Thanks,

Bill

Welcome to the Forum. Most members can usually help with problems.

Your trouble may be that the projection lamp is out of alignment. Remove the two lamp cover screws, then remove the lamp retaining spring by pulling towards you. Check that the small positioning pin in the rim of the glass reflector is in the notch which is towards you.

Hold lamp in position and slide back the retaining spring.

If this doesn't cure the problem then you probably have an old faulty lamp which you will need to replace. 12 volts, 100 watts. Type A1/231.

The lens is removed by pulling the focussing knob towards you, and whilst holding it out, gently remove the lens. When replacing the lens line up the lens holder pin with the groove in the lens. Turn the knob to see if the lens moves in and out correctly.

I don't think you can fit a better Sankyo lens, but if you are a mechanical fellow you might be able to fit something else. Perhaps another Member might be able to help. Of course, if the lamp is out of alignment you may get a brighter picture anyway.

Hope this helps you.

Hi Bill keep your eye out for the Sankyo 1.0 lens, its a cracker and really makes a difference on picture qaulity.
They do pop up from time to time.
Takes the picture up rather a lot, you really see a sharp increase in light and definition and for a 1.0 they are not too critical on focussing( some 1.0`s can be awkward to keep focused with some prints , a very good lens, fits all the Sankyo machines and also the Bell and Howell DCR DMC and DCT machines which are more or less Sankyos as well just with a different jacket.

Note to kev, I think we have email ditch doings again possibly, might be my server at the moment.

Hi Bill,

Welcome to the Forum. I agree with the previous comments made. Definitely looks like the optics are out of alignment somewhere. Shouldn't be too difficult to fix, though. However, irrespective of this, a new replacement lamp is always a good place to start when first acquiring a 'new' projector.

Good luck and enjoy your time with us.

Kindest regards,

When I removed the bulb and lens I noticed this in the piece of glass between bulb and lens. Not sure if cracked or fungus.

Hi Bill looks like a split glass heat shield, does it move out of the way when in projection mode or is it fixed.
Will it actually move out of the way, can you take it out to see if that helps.
I doubt the machine needs it for just a 100 watt lamp and they do cut the light down.
On some they or things like that pull away when projecting and just go back in front of the lamp when still if you will.
In the pic it looks fixed and like a bit of a good clean light stopper really.
You will dfeinately get a better pic without it if its constantly in front of the bulb when film is going through now.
Best Mark.

I've looked at mine and the glass unit does not move when projector is running.

From you pic it looks as if the glass in your unit is cracked.

It's probably a heat fiter. I can't offer any advice other than try and acquire a replacement from a scrap projector.

Or. I'm afriad you'll have to put it down to experience.

In that case just take it right out Bill and give the light a clean path, that will help allround.

How many sound super 8,s do you have now Maurice just out of interest.

Haven't got enough fingers and toes to figure it out.

Blimey !!!!!!

Posted by William Walsh (Member # 1261) on September 16, 2008, 02:47 PM:

Ok. Now the problem is getting it out. If I start taking it apart I'm afraid I'll never get it back together. Anyone with any experience taking this projector apart?

Hi Bill, job well done. Very handy these picture links too.
Looks like it was fine but you can see how it would cut down clarity of the light.
There may still be the other odd issue but its definately going to help and lift the light output etc.
