Wet LCD: the two liquids, and which one is yours

By Alberto Gulotta · Updated 23 September 2026 · 15 min read

A wet LCD has two liquids in it, and only one of them is yours. Turn the machine off, unplug it, tip it out to drain, and leave the rice alone. Then look at the mark on the glass: what you see tells you which of the two you are dealing with, and that decides everything after.

Is there liquid inside an LCD?

Yes, and that is the sentence that makes this fault confusing. It is also why “LCD display water damage” can name two different faults: the spill that reached the panel, or the panel’s own liquid crystal escaping through cracked glass. The panel in front of you is a sealed sandwich, and the layer in the middle of it is liquid crystal — the L and the C of the name. So when a screen goes strange after a spill there are two liquids in the room, and the whole of what happens next depends on which one you are looking at.

HP’s support page for a damaged display happens to describe both, a few lines apart, which is why it is worth reading even if your machine is not an HP. A discoloured, lighter or darker area is what HP attributes to liquid that has entered the panel: the spill, arriving where it should not be. Black blotches with bright white patches beside them are the other thing entirely — the panel’s own liquid crystal moving, and the white is simply where none of it is left. HP describes a third appearance in the same list, black splotches cutting across the screen, and gives it the same cause: “The internal glass has cracked and liquid crystal is leaking (sometimes called bleeding) inside the display panel along the crack.”

The practical difference: HP puts the other two down to cracked internal glass, and the first one only to liquid that got in. If what you are seeing is dark marks with no history of a spill at all, the fault is probably a different one and lives on black marks on a screen; the same goes for white spots and for the soft-edged shapes left by pressure on the glass, which are not liquid at all.

The first minutes, and the thing not to do

There is a published order for this, and following it costs nothing. It comes from iFixit’s wiki for a liquid-damaged laptop.

1. Turn it off, now, before anything else. iFixit puts this first for a reason it spells out: switching a liquid-damaged device off is “crucial to prevent electrical shorts and subsequent damage”. A screen that still shows something is a screen that is still powered, and powered is the state in which a spill does the rest of its work.
2. Disconnect every power source, and the battery if you can reach it. That means the charger as well as the outlet, and any USB device hanging off the side. The reason is the same one: liquids conduct, so anything still supplying current is still supplying the short.
3. Turn the machine upside down and let it drain. iFixit asks you to shake it, in those words — “remove as much liquid as possible” — and to wipe what you can see with a dry cloth. This is the last step that costs you nothing and can still help.
4. Do not put it in rice. Not as a folk remedy to be polite about: iFixit’s laptop wiki says to avoid rice and similar desiccants because “desiccants will not remove the contamination caused by the liquid spill”. Drying is not the problem you have. What was in the liquid is still there after it dries, and it keeps working on the metal.
5. Then open it, or decide not to. Everything past this point is a repair, and both iFixit and HP warn about doing it yourself. iFixit: liquid damage to a laptop “is not an easy repair, and even minor spills can result in issues that require a lot of tools and experience”. HP is blunter: “HP does not recommend repairing or replacing the screen yourself. This can void warranty options and cause further damage to the computer.”

The rice line is worth dwelling on, because iFixit says it plainly in two separate wikis. The laptop one is the one that applies here: avoid rice and similar desiccants, because desiccants do not remove what the liquid left behind. The general electronics wiki puts it as a warning — “Rice and similar desiccants will not help! These will create more damage in the long term as they do not remove the contaminants from the liquid spill”. Drying and cleaning are two different jobs, and rice does not clean.

What you spilled decides how much time you have, and iFixit publishes the numbers rather than a feeling about them.

Can a water-damaged LCD be fixed?

The honest answer is in one line of the same iFixit wiki, and it is not the answer the rest of the page would lead you to expect.

That line sits at the end of a section on evaluating the damage, where iFixit sets out the order in which the parts of a liquid-damaged laptop tend to go: the battery first, then the storage drive, then the display. Each of the first two has something you can do about it. A battery gets replaced, and iFixit says a submerged one probably has to be. A drive gets its contents copied to a dry drive, which is what iFixit asks you to try — or restored from the backup you already have, if you have one. The display is where the list runs out of remedies.

iFixit’s cleaning instructions are for the board and the parts taken out with it: submerge them in isopropyl alcohol at “90% or higher concentration”, brush the deposits off, check the connectors before reassembly, and “avoid all solvents such as ketone, acetone, or naphtha”. For the display the wiki gives no cleaning step, only the line about replacement.

If the panel is cracked, it is a replacement — and HP points out that a broken panel does not stop the rest of the machine: “LCD screen damage usually doesn’t affect the operation of the notebook computer”, and suggests connecting an external monitor and using the notebook like a desktop. If nothing on the screen is visible at all, the fault may not be the panel and the page for a screen gone half black or for backlight failure is the better start.

What the warranty actually says

This is the part that decides the money, and both makers publish it in plain language rather than in small print. HP gives the damage a name: “Accidental damage, such as spilling liquid on or dropping your PC is called Customer Induced Damage (CID) and is not covered under a standard warranty. Most damaged or broken LCDs are considered a CID.” Dell puts the same event in a list of examples, filed under the heading Liquid Crystal Display (LCD) as “Liquid Spillage”, and states the rule above the list: damages resulting from “accident, abuse, and misuse” are not covered by its limited hardware warranty.

Both also sell the cover that would have paid for it, each with a condition on when it can be bought. HP: its accidental protection plan “must be purchased prior to any damage occurring”. Dell: accidental damage coverage “can be purchased on any Dell system under active warranty”. Neither sentence helps with the screen in front of you; both are worth knowing for the next machine.

If the wet device is a phone rather than a laptop, the paperwork and the warnings are different enough to be a different page: an iPhone that refuses to charge because it has detected moisture is covered under the liquid-detected alert, and it is a warning about the port rather than a broken panel.

Not covered here. It will not take a panel apart. HP does not recommend it, in a sentence, and iFixit’s own warning is that liquid damage to a laptop “is not an easy repair, and even minor spills can result in issues that require a lot of tools and experience” — and a model-by-model teardown is what iFixit’s guides are for.

It gives no repair prices.

It is about a laptop or monitor panel. A wet phone is a different set of documents, and a MacBook that has been in water has its own guide on iFixit that this page does not repeat.
