Screen problems are one of the most common jobs on our bench, and they’re rarely as simple as “the screen is broken.” A crack, a flicker, and a line running down the display are three different faults with three different fixes, and mixing them up means paying for the wrong repair. Here’s how we tell them apart in our Perth workshop.
Physical cracks and spider webs
If you’ve dropped the laptop, sat on it, or closed it on something, and the glass or panel now has a visible crack, spider-web pattern, or patches of black or discoloured ink under the surface, the panel itself is damaged. This is the most straightforward case: the display panel needs replacing, full stop. There’s no cable fix or software update that repairs cracked glass.
The good news is that a cracked screen almost never means anything else in the laptop is damaged. The motherboard, storage, and battery are usually completely unaffected. We source the correct panel for your exact model, because laptop screens vary in resolution, touch capability, and connector type even across the same model line, and fitting the wrong one causes distortion or won’t work at all.
Flickering that comes and goes
Flickering is different, and it’s worth watching closely before you book it in. Ask yourself: does it flicker only at certain brightness levels, only when you move the lid, or randomly regardless of what you’re doing?
Flickering tied to lid movement almost always means a damaged display cable, not the panel itself. That thin ribbon cable runs from the motherboard, through the hinge, up to the screen, and it takes a beating every time you open and close the laptop. After a few years, or after one too many years of picking the laptop up by the corner of the lid, the cable frays internally. You won’t see damage from the outside, the fault only shows up when the hinge angle changes and the frayed strands briefly lose contact.
Flickering that happens regardless of lid position, especially at low brightness, more often points to the backlight driver or graphics output rather than the cable. This is a good case where guessing wastes money, and it’s exactly what the $85 inspection is for: we isolate the fault before quoting rather than swapping parts on a hunch.
Vertical or horizontal lines
Lines are almost always a panel or cable fault too, but the pattern tells us which. A single coloured line that stays in the same spot regardless of what’s on screen usually means a dead pixel column inside the panel itself, and the panel needs replacing. Lines that shift, flicker, or multiply when you flex the lid slightly are a cable symptom again, the connector or ribbon is making intermittent contact.
One thing lines are not, in almost every case: a sign that your graphics card or motherboard is failing. That’s a common fear we hear at drop-off, and it’s rarely the reality. If we do suspect a graphics or motherboard fault, we’ll test it against an external monitor before quoting anything, because that one check settles it in minutes.
Dim or completely black screen with the laptop still running
If the laptop powers on, you can hear the fan, and maybe you can even see a very faint, ghostly image on the screen if you shine a torch at an angle, the panel is fine. The backlight has failed, either the inverter (on older laptops) or the LED driver circuit (on newer ones). This is one of the more affordable screen faults to fix precisely because the expensive part, the panel, isn’t what’s broken.
What we actually do about it
Every screen job starts the same way regardless of the symptom: a technician has it on the bench within 2 to 3 hours of drop-off, tests the cable, backlight, and panel independently, and calls you with a written quote rather than assuming the worst. Standard screen swaps where we hold the part run same day to 24 hours. If your model needs an order-in panel, that’s typically 2 to 3 business days. Every repair carries a written workmanship warranty, and board-level fixes for cable connectors or driver circuits are done in-house rather than farmed out.
We don’t publish a flat “screen repair” price here because the real cost depends on your laptop’s exact model and which of the four faults above you actually have, not a guess based on the symptom alone. Our pricing page has typical ranges, and you’re welcome to compare us against the hundreds of Google reviews from other Perth laptop owners who’ve had us diagnose the same problem.
If your screen is cracked, flickering, or showing lines, don’t buy a replacement panel and try to guess. Book a proper diagnosis first, it’s the only way to know which of these four faults you’re actually paying to fix. Get a quote and we’ll have an answer for you the same day.
