LCD Dust

many thanks

What a funny thread to come back to with a cup of coffee. I trust Mark from following many of his previous posts but checked out DPreports anyway. Apparently the LCD cover is a hard scratch-resistant plastic, and mine has dust underneath it. I would love to take an example picture but...without some kind of mutant stretch armstrong lensbaby, I don't see that happening.

Amazing how some people just "know" things.

Abuser, try this test: take a pocket knife or steel point scriber. Drag it across your LCD screen - don't push any harder than you would writing with a pencil.

Did it leave a scratch? Then it isn't glass. Glass is harder than that.

Don't use a carbide point scriber - it will scratch glass also.

Report back with your results.

I'm sure by now everyone wants to see some snake photos from your back yard.

yeah but getting dust on the lcd screen, when i know by experience of dealing with electronic equipment, the lcd is sealed up, there is no way dust is going to get in full stop or period for you american guys

Yep, I'm so sure you're experienced with electronic equipment

Both LCDs on ALL Canon dSLRs aren't directly exposed to the outside world. The camera body has a plastic protective cover that fits into a slot on the body that covers and protects the LCD screen.

http://www.customslr.c​om …S_20D_Parts%20C​atalog.pdf

Scroll to Page 4 of that PDF (page 1 on the actual manual, it's the page with the camera facing towards the top-left). You'll see part numbers CB3-1651 and CB3-1831. Those are plastic covers that protect the actual LCD which is connected to various PCBs via ribbon cables on the inside of the camera.

Common in electronic equipment is dust that settles inside the devices on top of the LCD screen. My Motorola RAZR V3 cell phone has dust on the inside of both of it's LCDs, my Creative Zen Vision:M MP3 Player has dust on the LCD (partially because of my disassembly). The reason is because none of these devices are completely sealed free of dust (A 1D(s) series camera may possibly be dust-free however). Thus, dust works it's way in, and gets stuck under the plastic LCD cover.

more than u do

I don't know what the LCD cover is made of but I do know that when I shoot snakes I prefer to use a shotgun.

Hehehe, this made me laff!!! I have dust under my plastic LCD protector! (Mine is a 40D one, not a high spec Unique Glass one like 400dabuser has!) It seems to be blown in from the bottom left corner and spreads out like it has been blown across the LCD itself.

Obviously 400dabuser will automatically assume i am wrong and that there is no dust there.
He would know what i mean far better than i do, i am only here right in front of the offending camera staring at the problem, whereas 400dabuser is 324miles away in london! How could i possibly have any idea what i am talking about???

you must have a very funny navy then, no im not insulting the US ok?

I know I'm late to this "discussion" but be careful what you say about our Navy... There are a lot of us on here who have devoted a good part of our lives to the Navy (and other of the US Armed Forces...)

I just got out all five of my Canon digital cameras and every single one has dust under the back LCD cover, including my brand new, less-than-a-week-old 40D. It just a fact of life and nothing to obsess over.

I just really enjoy these threads where someone asks a question and we all try to clarify and the OP argues with you. I find this very frustrating and entertaining at the same time. Even when you give a link to some documentation, the OP still insists you are wrong.

The truth is, dust is everywhere, in under the clear (who really cares glass or plastic) cover, on the sensor, in the viewfinder, on my glasses. Everywhere. I've just learned to ignore it if the LCD is dusty and the viewfinder. But the sensor is something I can take care of.

What exactly did you want to do? If you can take the cover off the LCD, then what?

Thanks for bringing this one back to life Rich. Funnier than plastic pooh.
