Hinge overwhelmingly too tight

Looks like I had the naming convention for the right and left hinges backwards in my OP, whoops. Alright, so I'll try the WD-40 on the hinges first, should I do anything to clean them beforehand? And in regards to the camera wire, I have some reservations about the display teardown guide. It looks like something i should avoid because the LCD ends up being destroyed. It also doesn't give any explanation into how it happened or ways to avoid it. Would it be possible to remove the terminal(s) from the lower case-side of the wires to thread them new hinges and reattach them after?

Would WD-40 be a safe lubricant for a computer? I've seen people online saying not you use petroleum-based lubricants and instead using silicone, graphite, or lithium-based lubricants.

The trick here is not to spray into the system!

Using the method I've outlined will surgically place the WD40 into the hinge as its a penetrating oil it will seep into the hinge.

surprisingly silicone, graphite and lithium grease are all not good for your computer for different reasons. Silicone is a surfactant so it slowly spreads and is a bear to clean off. graphite is a dust or held in suspension with a solvent or oil so it will loose the carrier and drift away or just make a mess in a cloud of dust. Lithium is a heavy grease and just can't get into the hinge. Great for car's not so much for computers unless you disammble the parts which we can't here.

I use WD40 without any problems for over 40 years of computer repairs. I've gotten in systems in which have been destroyed by peoples efforts with lubes. Most of the time people just aim the spray can and let it rip! Giving is a good shower dripping wet when they bring it in.

Just remember it only takes a little bit! Just carefully placed. Thats all thats needed.

Sounds good to me, I didn't know about the issues with the others, thanks! What about 3 in 1 Oil, I've seen reports of a few people putting this on instead of or after using WD-40. I guess the thought is after the volatiles evaporate off, the hinge goes back to feeling as "tight" as it did before using the WD-40.

Also I forgot to mention that if I over-tightened the hinge screws, the screen would pop open on its own in the past. I was trying to avoid this earlier, but now I think the poor lubrication has become the main culprit.

When i first installed the new display, I had issues getting the hinge to sit flush with the bottom case. I figured tightening the 6 screws would make them flush. When the display would pop open on it's own, I would slightly unscrew them until I found the sweet spot where it wouldn't automatically open and wouldn't wiggle. I'm worried this may have caused the an issue to form over time with the hinges.

Don't uses anything else!! Stick with the WD40 !!

Do Make sure the hinges aren't cockeyed!

Take a straight ruler lay it across the hinges on both tangents (90º from each other)

Did you forget the spacers??
