I just bought this Sankyo Stereo 800 with a portable screen (of no value really) and a Bauer S 205XL camera for 50 GBP. The Sanky is running okay on 18 fps, but uneven in 24 fps. It seem to be worse when switching between the two and sometimes it even stops totally. You can hear the uneven running in the video. If anyone has a tip to make it stable, please let me know as it seems to be a quite nice projector

Hi Vidar,
I had a Sankyo Stereo 800 for a few months. I sold it as it had way more sound capabilities on it than I needed. I wish I'd kept it though. It's a lovely machine. Looks nice.

One problem I had with it though is that I felt it let too much light out through that top grille, making the room quite bright. Have you noticed this?

Still an absolute bargain Vidar!! Well done, never had one so I cannot advise, but a very very nice non- scratching machine from all accounts. [Smile]

Thanks ... I can not say I've noticed that, but then again, I just brought it in the door and had the lights on in the room due to checking what was going on

It was running really bad film very well. (I dont dare to test good films on new projectors, wuzz that I am) ... Not as picky as the Elmo's. Do hope I can get it running steady. I am thinking, long time in storage, maybe it needs some lubrication, but I have no idea where to lubricate (so the lubrication doesn't affect the belts or anything. Not so nice with oil splashing around in there I suppose)

Vidar, lots of people on here have owned these very nice machines for years, let them advise you on how to proceed in both lubrication, maintenance as well as quirk advice. I am sure you will have struck gold here in no time!

Try and pick up the Sankyo Hi Pro lens for it. They're quite expensive but apparently excellent.

Click on "Manuals" to the left of this page, Vidar. There's a manual there for this machine.

Hi Vidor

I watched you video 10 times;

Here is how I would proceed.

1. Remove belts off pulleys.
2. Check to see if pulley are turning freely.
3. Check to see if main shaft turn freely by hand. (use knob on front of projector)
4. If any pulleys are not turning freely, 1 drop of light oil only. I use 3in1 or sewing machine oil, or gun oil.
5. Do the same thins for mail shutter shaft if needed.
6. After all this is done relax and enjoy your new projector.

Good luck!

Gun oil ! You're a real American [Wink]

Thanks for the tips Pat, will try to see if I manage that without destroying it :-)

Hi Vidar

Before you go ahead removing things, try doing this.

Spray some evaporative contact cleaner onto the 2 speed switch. Work the switch back and forth a few times to clean the contacts inside. Spray again if its still the same and repeat the switching back and forth.

That may fix the problem. Its worth a try. Let us know how you get on.

I will try that too (and first :-) ) ... It do react when I move the switch, so it might well be that, but since this is an apparent common thing (from seeing the other posts about the 600's and 800's), has no one got this to work if it's that simple?

Hi Vidar. Had the 800 from new back in the day and mine was problems out of the box. Back then a service engineer (long story) talked me through the noted fault and repaired literally over the phone. These models suffer from a batch of dry solder joints and the problem with mine was around the speed control board where it meets the main board. I simply had to re-solder the board and it was fine. It was causing the motor to slow even stop. Put a rubber glove on run the machine and gently move the board just 1mm or so and you will soon see if it affects the running of the motor. With yours it could even just be a sloppy main drive belt.

Had a few over the years and other things to look out for due to insufficient lamp cooling and bending of the swinging gate (you will see this clear enough), scratching due to excessive use, non replacement of parts also worn focus knop pins making for sloppy focus and the top of the lamp house will warp with the lamp heat being plastic.

I liked the projector once it was running and gave many shows out and about even with the standard lens in. A good light machine with plenty of amp power for larger rooms.

Thank you, Lee. So it's fixable :-) If it was the belt, wouldn't just the reels go uneven and not hear the motor slowing and stopping? I will try to see if I can locate that board and resolder it, if the board isn't located in a place where all needs to be removed (hate that). Appreciate the tips, now I have something to check for

Posted by Lee Mannering (Member # 728) on July 02, 2014, 06:03 AM:

It looks clean enough inside Vidar which is a good start guide as to condition. From memory its the small vertical board to the left you need to very gently move when the machine is running. Be very careful of the electrics OK. Could be worn motor brushes as well perhaps but if you decide to take them both out for inspection only loosen those black retainers by hand as they will crack.

Vidar,

I just noticed another member is selling one of the Hi Pro lenses in the equipment for sale section, in case you're interested.

Posted by Vidar Olavesen (Member # 3354) on July 02, 2014, 12:52 PM:

Thanks, I saw it, but since this is a third choice projector, I'll stick with the lens I have. Appreciate the tip

We must not forget that our beloved projectors are now getting quite old, dry joints seem to be a continual problem, but hopefully they are a usually cleared problem. However, it's often time consuming to find the actual joint to apply your soldering iron.

The Sankyo breed (and the badged Bell & Howells) are great projectors, I have quite a few.

Posted by Vidar Olavesen (Member # 3354) on July 03, 2014, 09:12 AM:

Seems like it runs nicer now ... I tried wiggling the board a little, didn't help too much, but after changing many times between 18 and 24 fps, it seemed to be better. So I'll try the spray and hopes it will be okay. Does look like it's chugging a little on the perforation as it feels smoother before it enters the projector than when it comes out. Will try a clean and a compressor to blow out any debris that might be there. Can't see any, but doesn't mean it's nothing there

Thanks for all suggestions
