Squeaky clam shell

[SDinSD]

My NR70V has developed a squeaky noise when opening or closing it. I read one forum post that suggested a lite application of WD40 with dental floss. Any other solutions out there?? :confused: :confused:

I use graphite "Lock Lubricant" because it comes in a dry form. Don't overuse it or you'll have gray fingers the next day :D :D :D

[pigburger]

Where do you get said "lock lubricant"?

[Caveman4810]

Good hardware store such as Home Depot is where I think I got mine. It lasts a good long time, so it's hard for me to rememereeee.........

JB:rolleyes:

How and where did you apply the lock lubricant Caveman?

I am having the same problems with mine. It used to move smoothly and now it creaks a little. Not noisily, it just takes a little more pressure to close. It's only roughly 1/2 year old!

SDinSD I did mine yesterday. I sprayed WD-40 on the blade of a pocket knife (to get just the right amount) then touched the point to the hinge area, to apply the right amount.

Worked excellently. Also did the screen pivot.

My NR70V had the very same problem. It's good to know that mine wasn't the only one. At first it didn't bother me, but then it got so annoying I was gonna use WD-40 too. I called Sony Support anyhow and they told me not to use that because if it made anything defective then I would lose my warranty. They told me to send it in which I did. They paid for shipping and handling. My Clié was sent on the 9th of January it was received by Sony on the 10th of January and was back at my home on the 13th of January. Good service huh???:D

[Caveman4810]

As a service tech for over 20 years I have seen and used WD-40 many times. I use it for prep & clean-up before and after I lubricate anything. It is a fine solvent not a good lubricant. It's lubricating affects are short term in most applications. You are better off using a light oil (that doesn't have the penitrating affects of WD-40) or a silicone based lubricant. These products will do the job much longer. I have also used dry lubricants (with much sucess) in applications where electronics are concerned because any liquid has a tendency to pass current. The next time you have a door hinge, etc. to lubricate, use an oil based spray lubricant(or silicone) instead of WD-40 and you won't be lubing it again in three months. You will probably have moved out of the house by the time it needs more lubrication.
This is not a put-down of WD-40, just a lesson about it, born from experience.

Thanks for the replies - Two questions:

Ognib3309: Did the "rework" that ws performed by Sony completely solve the problem?

Caveman4810: Please tell us more about the dry lube. Are you talking ground graphite (kinda like pencil lead). As an obvious guru of lube, is that what you would recommend in this case?

Thanks - any enjoy.

Caveman4810 - I followed your advice. I used very thin lubricating oil that came with my electric razor...and it worked great!!!! I found a thick sheet of paper, drizzled the thin liquid on the paper and then ran the paper through the hinge cracks. About two passes each side. Volia - my silly little problem solved.
Thanks - and enjoy your Clie.

Don't use graphite. It's conductive and can cause you major headaches if it gets on electronic components.

Use a drop or two of silicon lubricant instead.

[Caveman4810]

I guess my point is:
Whatever you use - Use it sparingly...If you use oil/silicone/graphite it's effects will last... WD-40 has much more penitrating power (which is what we want to avoid) and it long term lubricating is not near as good as the others.... The fewer times you have to re-lubricate the less the chance of problems. Any of these products can cause problems with electronic circuits if overused.

[Caveman4810]

[CK] Didn't realize grapite passed current. I guess I've been lucky and had enough sense to use it sparingly!

Chemistry: C, Elemental Carbon
Class: Native Elements
Subclass: Non-metallics
Group: Carbon
Uses: for the lead in pencils, as a toughener of steel and as a lubricant.
Specimens
Graphite is a polymorph of the element carbon. diamond is another polymorph. The two share the same chemistry, carbon, but have very different structures and very different properties.

Diamond is hardest mineral known to man, Graphite is one of the softest.
Diamond is an excellent electrical insulator, Graphite is a good conductor of electricity.
Diamond is the ultimate abrasive, Graphite is a very good lubricant.
Diamond is usually transparent, Graphite is opaque.
Diamond crystallizes in the Isometric system and graphite crystallizes in the hexagonal system.
Somewhat of a surprise is that at surface temperatures and pressures, Graphite is the stable form of carbon. In fact, all diamonds at or near the surface of the Earth are currently undergoing a transformation into Graphite. This reaction, fortunately, is extremely slow.
All of the differences between graphite and diamond are the result of the difference in their respective structures. Graphite has a sheet like structure where the atoms all lie in a plane and are only weakly bonded to the graphite sheets above and below. Diamond has a framework structure where the carbon atoms are bonded to other carbon atoms in three dimensions as opposed to two in graphite. The carbon-carbon bonds in both minerals are actually quite strong, but it is the application of those bonds that make the difference.

Graphite can only be confused with the mineral molybdenite which is metallic bluish silver in color. However, molybdenite is much denser and has a silver blue streak.

Most graphite is produced through the metamorphism of organic material in rocks. Even coal is occassionally metamorphosed into graphite. Some graphite is found in igneous rocks and also as nodules inside of iron meteorites.


PHYSICAL CHARACTERISTICS:
Color is black silver.
Luster is metallic to dull.
Transparency crystals are opaque
Crystal System is hexagonal; 6/m 2/m 2/m
Crystal Habits include massive lamellar veins and earthy masses. also as scaly granules in metamorphic rocks.
Hardness is 1 - 2
Specific Gravity is 2.2 (well below average)
Cleavage is perfect in one direction.
Fracture is flaky.
Streak is black gray to brownish gray.
Associated Minerals include quartz, calcite, micas, iron meteorites and tourmalines.
Other Characteristics: thin flakes are flexible but inelastic, mineral can leave black marks on hands and paper, weakly conducts electricity.
Notable Occurrences include New York and Texas, USA; Russia; Mexico; Greenland and India.
Best Field Indicator is softness, luster, density and streak.

My NR70 also creaks and is stiff. But I have to wonder if Sony engineers where smart or fore-sighted enough to do that on purpose (ie, design it to tighten up as it ages). My major concern when I originally bought the unit was that the hinge would become loose and the screen would start flapping around.

[pigburger]

No flapping after 7 months, just a little play and creaking is all. Will definitely try the silicon lubricant for the creaking.

Jstimson, you a Senators fan?

[Ognib3309]

By "ws" did you mean the warranty service? If so, yes after I got my Clié back from Sony repair it worked perfect. My invoice showed that they added a "spacer" to it. Hope that helps.

[yOyOYoo]

Do they warranty scratched casing? Like my cases have a lot of scratches on it, esp. on the closed screen part,where the two rubber tabs scratch the palm when it is closed.

Will sony replace my magnesium casing?

I really need my hindge fixed. and the MS problem too. But my worries are, if I have sony fix it, then I have nothing to complain to best buy about when the TX65 comes out....

I didn't want to upgrade to the NX yet because of the CF hump. Although the hindge on the NX does feel very sturdy. Maybe I should upgrade. haha

[jetdriver]

I bought my NR70 the week CompUSA in Cleveland got them - May 2002 if I remember. Its been creakin like crazy for the last month... So - I sprayed a little WD40 on some floss (before finding this thread) and ran it through each hinge pivot point.

So far, its nice & smooth - no problems. But - if it comes back, I have some dry aviation lubricant that a mechanic gave to me. Some kind of silicone based material. Might try that if the problem comes back.

[pigburger]

I don't think Sony will cover case scratchings, It's like a car dealer covering highway pebble dings, it's normal wear and tear.
