No light going through lens despite functioning bulb and mirrors

The blackout shutter is on a very sensitive "trigger". When the two silver pressure pads that push against a slide inside the gate (aperture) are flat against the gate- that is no slide in place - the pads are linked to the trigger and make the blackout shutter stay up, blocking light from hitting the screen when no slide is in place. When there is a slide, the pads trigger the spring mounted shutter to fall down.

Least likely but possible is that the spring has come off one end of the shutter.If so, disassembly of the projector casing , not the mechanism, will be needed.

Most likely is that the trigger is out of adjustment. It's fairly simple but if you overcompensate and/or don't understand exactly how it works you can end up with the shutter not working at all.If that happens the projector will still work but the light will flash on the screen at each slide change. So whether you want to tackle it will depend on your comfort zone as far as 'fine" adjustments go. If you don't get it right you may have to do some major dissasembly of the projector to get to the mechanism. You will not need to take any part of the mechanism apart however.

Just thought of one other possibility. Look into the side of the gate where the slides fall into, with a strong flashlight. you'll see the trigger (black, part of the shutter itself) and you may be able to see where it makes very tenuous, light contact with another part of the mechanism (depending on the model). Carefully clean it with a Q-tip and WD 40 or alcohol. Be careful not to leave any cotton behind. Then apply, with the tube of the Q-tip, some very light grease, and only a tiny bit. Recommended is Super Lube with Teflon available from many industrial supply stores and inter net sites.If the old lube and/or dirt have piled up there, this may be all you need to do.

As for docjibe's problem with no forward/advance, it's a common problem and it means a critical nylon link has broken inside. it usually takes an expert to do the job correctly. In a pinch, you can, with some experience to get the right "touch", gently and quickly brush down and outwards with your thumb, on the grey button marked Select.The tray will usually advance.

How do I change the bulb in the door mirror on a Volvo S80 2004


If it's the approach light under the mirror, the lens pops out to replace the bulb. If it's the turn signal bulb, then the mirror cover has to come off

Replace optrel satelite evolution battery?


I recently learned something new about these helmets. I really like like the fit and comfort of the OPTREL helmets; best I have ever owned, but the dying, irreplaceable battery thing drives me crazy. What makes it worse is that I spent over $400 to purchase mine and it lasted only 2 years. Unfortunately, I trashed my first one, trying to replace the batteries. Don't do what I did, or at least try this first. Hopefully this will restore full functionality to your helmet.
First step is to cover the sensor ports with opaque tape. These are the little ports on the AD Cartridge, which are located below and to the inside of the photo-voltaic (PV) charging cells. Covering these ports prevents the auto-darkening function from working, while the batteries are being charged. I used masking tape which was covered with black vinyl tape so it was both easy to remove and it completely blocked light from passing through. Next step: Prepare a charging source by placing a CFL light bulb in a utility work light fixture. Mine was an aluminum, reflective fixture with a spring clamp for holding it in position. The bulb must be at least 23W (100W equiv.) and probably not more than 50W, to prevent overheating of the helmet and AD Cartridge. There are likely other light sources which will work as well, the objective being to provide ample and constant charging energy without overheating the helmet or AD cartridge. Position the lamp about 6 inches from the PV cells, immediately in front of the helmet so that the PV cells are able to capture as much of the light energy as possible. The lens should not be darkened in this state, due to the sensors being covered. Test by placing a 3x5 card, or something similar, between the light and helmet. The lens should not darken when exposed to light. The helmet can remain in this state for as long as you like. I left mine to charge for 5 days, after which it was able to maintain the darkened state with no issues.
On occasion, I think it may be beneficial to cycle the batteries on this helmet, i.e., discharge and then recharge. This can be accomplished by placing opaque tape over the PV cells, to temporarily defeat the charging function. Place the helmet in front of the light source, similar to the arrangement described above, positioning the helmet in such a way as to trigger darkening of AD cartridge lens. Note that the sensor ports must be uncovered for the lens to darken. Darkening the lens consumes battery power so leave the helmet in this state until the lens is no longer darkened, which could take hours to days, depending upon the condition of your batteries. Test lens darkening by placing something like a 3x5 card between the light source and sensors, which will cause the lens to transition from dark to light. Once the battery is sufficiently discharged, to a point that the lens no longer able to maintain the darkened state, then recharge the batteries using the procedure described above. Do not leave the helmet with batteries discharged, as this could cause permanent damage to the batteries and AD Cartridge. Hope this works for you. Best Regards.

What is an optical block


LCD and PLASMA sets do not use them---LCD rear projection sets that have a lamp for the light source use them: light from lamp shines into the engine and picture with color emerges from lens at top of optical engine, it shines into a mirror which projects it on the front screen---Display is LCD but with a mirror it is also rear projection.

I have an Optrel Satellite and the auto-darkening function has stopped working (weeks before I take my journeyman's, wouldn't you know?) It is no longer under warranty....can anything be done to fix it?

Image is half dark, despite lens changes


Hi there
The blacked out part is the bottom of the photo therefore the obstruction is at the top of the frame on the camera.
Try the camera on the BULB setting without a lens on & look into the throat of the camera. You should see what is not clearing the CCD completely.
It could be the sub-mirror which is a little mirror behind the main one for the AF function or a shutter blade not clearing enough.
I would go for the first one.
It could be because.....
1. the sub-mirror spring coming off or broken
2. the sub-mirror is glided by a post on the side of the mirrorbox & this could of come adrift.

Most repairers can deal with this fault. If the spring has come adrift you should be able to pop it back in place.
All this may not solve your problem but it will at least give you better idea of what you are dealing with.

Toshiba TDP D2 Projector


A mirror got loose in the opening from where the bulb sends the light to the "panel" It is blocking part of the light.

I'm not talking about one of the tiny mirrors that makes up the DLP, but there is silver box where the bulb light initially goes. the walls are lined with mirrors whose adhesive fails when exposed to great heat.

I can easily fix it, as i have fixed many of them from this problem.

Replacing light bulb on dryer


Light is located just above the door on the inside of the drum. It has a clear plastic lens on it. The lens has a hinge on the top and a retention feature on the bottom. You can see all of this with a mirror. Simply push the button up and the lens will swing up. You can then access the light bulb.
