Laptop screen replacement, matched at part-number level not screen size
Cracked glass, dead backlight, flickering hinges, lines across the image. We test the display chain before we sell you a panel — because roughly a fifth of "dead screens" that reach our bench are healthy panels behind a broken backlight circuit.
Display faults from this week's bench log

What is actually inside your screen
A laptop display is not one part. It is a stack: a backlight assembly of LED strings and a light guide plate; a diffuser and prism film set; the liquid crystal matrix itself; a polariser; and a timing controller (TCON) board bonded to the panel's edge. Feeding it are an eDP cable running from the mainboard through the left or right hinge, and a backlight boost circuit on the mainboard that steps battery voltage up to the 20–40V the LED string needs.
That structure explains every symptom you will ever see. Cracked glass with a working image? The polariser and matrix are damaged, the electronics are fine. A faint image visible under a torch? The matrix is switching but the backlight is dark — and the fault may be nowhere near the panel. Flicker that changes when you move the lid? The eDP cable is chafing where it wraps the hinge. Bright vertical bars? The TCON or its ribbon bond. Understanding the stack is the difference between a S$40 fuse and a S$450 panel, and it is why we never quote a screen from a photo alone.
Panel, cable, backlight or GPU? How we tell
Four tests, in order, before anyone reaches for a part:
- External monitor test. Plug the laptop into an HDMI or USB-C display. A clean external image proves the GPU and the display output are healthy, which immediately narrows the fault to the panel, the cable, or the backlight. A corrupted external image points at the GPU — a board-level repair, not a screen job.
- Torch test. Shine a light at an angle on the dark screen. If a ghost image is visible, the LCD works. The backlight does not. We then measure the backlight rail on the board with a scope; if the boost circuit outputs nothing, the panel is innocent.
- Cable flex test. With the machine running, we articulate the lid slowly through its full arc while watching for flicker, colour shift or dropout. Positional faults are cable faults, full stop.
- Known-good panel swap. The last resort and the definitive answer. We connect a bench panel of matching interface. If the bench panel lights up, yours is dead. If it does not, the fault is upstream and we have just saved you the price of a screen.
The torch test costs nothing and takes ten seconds. Do it before you accept any quote for a screen replacement anywhere in Singapore. If you can see your desktop faintly, ask the shop to show you the backlight rail voltage. The good ones will.
Send us a photo of the screen and the model number
We will tell you whether you are looking at a panel, a cable, or a backlight circuit — and what each one would cost — before you bring the machine anywhere.
LCD, IPS, OLED and touch: what you have and what it costs
TN panels survive on budget machines: fast, cheap, poor viewing angles, and inexpensive to replace. IPS is the modern default — accurate colour, wide angles, and the panel type in perhaps three quarters of the laptops on our bench. High-refresh IPS at 120Hz, 144Hz, 165Hz or 240Hz appears on gaming machines from ASUS ROG, Lenovo Legion, MSI, Acer Predator and Razer Blade; fitting a 60Hz panel into one of these is a downgrade you would notice within a minute, and it happens more often than the trade admits.
OLED panels — increasingly common on Samsung, ASUS Zenbook, Dell XPS and Lenovo Slim lines — are gorgeous, expensive, and vulnerable to burn-in on static UI elements. Replacement cost is meaningfully higher, and there is no third-party equivalent worth fitting. Bonded touch assemblies on convertibles and Microsoft Surface devices laminate glass, digitiser and panel into one unit; the whole assembly is the service part, which is why Surface Pro screen replacement is genuinely expensive and why we quote it honestly rather than optimistically. MacBook Retina lids follow the same logic and are covered on our MacBook repair page, including the flexgate cable defect on 2016–2017 Pro models.
Matching a panel properly — the part nobody explains
Every panel carries a model code printed on its rear label. That string, not the screen size, determines compatibility. It encodes six things, all of which must match:
- Resolution. Obvious, and the only one most shops check.
- Refresh rate. A 144Hz machine fitted with a 60Hz panel will run at 60Hz forever.
- Connector pinout and position. 30-pin and 40-pin eDP both exist, and the tab may be left, right, top or bottom. Physically incompatible panels look identical in a listing photo.
- Brightness. 220, 250, 300, 400 or 500 nits. Fitting a dim panel in a bright chassis is the single most common complaint we hear about other people's repairs.
- Colour gamut. 45% NTSC versus 100% sRGB versus 100% DCI-P3. Designers and photographers notice immediately. Everyone else notices eventually.
- Surface and thickness. Matte versus glossy, and the panel depth that lets the bezel close correctly.
We quote against the part number and we tell you when a panel is an equivalent rather than an identical SKU — and what the difference is in nits and gamut. If the price we quote seems higher than a listing you found online, it is usually because the listing is a different panel wearing the same diagonal.
Hinges, bezels and the fault nobody quotes for
A surprising share of "screen problems" begin at the hinge. As the mounting threads work loose — endemic on cost-engineered Acer and HP chassis, and common on Dell XPS — the hinge starts levering against the plastic instead of pivoting. The bezel lifts, the palm rest cracks, and eventually the hinge tears its bosses out. Along the way it crushes the eDP cable, which is why the flicker started.
Replacing the panel without rebuilding the hinge mount means the new panel takes the same abuse. We rebuild mounting bosses with brass inserts and structural epoxy, replace worn hinges where the friction pack is spent, and route a fresh cable with the correct service loop. It adds an hour. It is the difference between a repair and a deferral. If a quote you have received mentions a panel but not the hinge on a machine whose lid does not sit flush, ask why.

Our replacement process
Display-chain diagnosis
External monitor, torch test, cable flex, backlight rail measurement. We identify which of the four possible faults you actually have.
Part-number capture and written quote
We read the panel label, confirm resolution, refresh, gamut, brightness and connector, then quote a fitted price that does not move.
ESD-controlled disassembly
Grounded mat, wrist strap, battery disconnected before any cable is touched. Bezels removed with nylon tools, never metal.
Fit, seat and structurally check
New panel fitted, eDP seated with the correct service loop, hinge mounts inspected and rebuilt if compromised.
Test across the full arc
Uniformity, dead-pixel scan, brightness ramp, and a slow lid articulation from closed to fully open, watching for any flicker.
Written warranty on your job sheet
Part and workmanship covered, terms printed, old panel returned to you on request.
Preventing the next cracked screen
Four habits account for most of the cracked panels we see. Closing the lid on a pen, an earphone or a USB stick left on the keyboard — the single most common cause, and entirely avoidable. Lifting the machine one-handed by a corner of the open lid, which twists the panel in its frame. Carrying it in a bag with a hard object pressing on the lid; a 3mm ridge across a closed laptop is enough. And ignoring a lid that no longer closes flush, which means the hinge is already tearing out and the panel is already under stress.
Beyond that: clean the screen with a dry microfibre cloth or a screen-safe spray applied to the cloth, never to the panel. Household glass cleaners contain ammonia and will haze the anti-glare coating permanently. And if you drop the machine, get the hinge and cable inspected even if the picture looks fine — the crack that appears three weeks later usually started that day.
Why customers choose iDevice for screen replacement
Because we test the display chain before we sell you a display. Because we quote against the panel part number and tell you when we are fitting an equivalent. Because we rebuild the hinge that broke the screen rather than shipping the machine back to break it again. And because customers walk in from the CBD, Orchard, Novena, Toa Payoh, Bishan, Ang Mo Kio, Jurong East, Bukit Batok, Clementi, Queenstown, Tampines, Bedok, Woodlands, Yishun, Hougang and Punggol, and 4.8 stars across 940+ reviews is not something you keep by guessing.

Questions we get every week
Laptop screen replacement questions, answered properly
How much does laptop screen replacement cost in Singapore?
Realistic ranges, and we publish them because vagueness benefits nobody. A standard 1080p IPS panel on a mainstream 14–15" laptop sits around S$180–280 fitted. High-refresh gaming panels (144Hz and above), 2K/3K panels, wide-gamut creator panels and OLED panels run S$320–650. Touch-enabled and bonded assemblies — Surface, most convertibles, MacBook Retina lids — sit at the top of that band or above, because the digitiser and glass are laminated to the panel and the whole assembly is replaced. We confirm the exact figure once you send us the model, because the panel part number, not the screen size, sets the price.
The screen is cracked but the image still works. Do I have to fix it now?
Not urgently, but the clock is running. A cracked panel lets moisture and dust reach the polariser and the LED light guide, and the crack propagates every time the lid flexes. More importantly, glass shards work their way into the hinge channel and into the eDP cable, which turns a S$200 panel job into a panel plus cable plus hinge job. If you can live with it for a fortnight, fine. Six months is a false economy.
Is a replacement panel the same quality as the original?
It is if the technician matches the part number rather than the diagonal. Every panel carries a model code — for example an LP156WFC or an NV156FHM — that encodes resolution, refresh rate, colour gamut, brightness in nits, connector pinout and backlight voltage. We match resolution, refresh, gamut and brightness class, and we tell you plainly when a panel is an equivalent rather than the identical SKU. Where the original was 100% sRGB at 300 nits, we will not fit a 45% NTSC 220-nit panel and call it a screen.
My screen goes dark but I can see a faint image with a torch. Is the screen dead?
Almost certainly not. That symptom is the classic backlight failure: the LCD is switching correctly, but the LEDs behind it are not lit. The fault is either the backlight boost circuit on the mainboard (a blown fuse, a failed inductor or a dead driver IC), the panel's LED string, or the backlight enable line. Two of those three are a board-level repair costing far less than a panel. See our motherboard repair notes. A shop that quotes a panel without testing the backlight rail has not diagnosed anything.
Can you fix dead pixels or backlight bleed without replacing the screen?
No, and neither can anyone else, whatever a YouTube video promises. A dead subpixel is a failed transistor in the panel matrix; there is nothing to repair at that scale outside a fab. Backlight bleed is a mechanical consequence of how the light guide is clamped, and pressing on it either does nothing or makes it worse. Stuck pixels — permanently on rather than off — occasionally free themselves with a pixel-cycling video. That is the honest limit of the trick.
How long does the repair take?
Most standard panels are a 45–90 minute job once the part is in hand, so same-day is normal if you tell us the model in advance and we have it in stock. Bonded touch assemblies, MacBook Retina lids and machines needing hinge rebuilds take one to three days because the adhesive needs a controlled cure. Rare panels ordered to your part number typically land within two to five working days.
Do you replace the whole lid or just the panel?
Whichever is genuinely correct. On a serviceable laptop we replace only the panel, keeping your bezel, hinges, camera and antennas — cheaper for you and less waste. On bonded assemblies (Surface, many convertibles, MacBook Retina) the panel is laminated to the glass and, on some models, to the lid itself; there the assembly is the part. We will always quote the panel-only option first if it is possible.
What warranty covers a new screen?
Every panel we fit carries a written warranty on the part and our workmanship, recorded on your job sheet. It covers panel defects — dead pixels appearing, backlight failure, TCON faults — and anything traceable to our fitting, such as a cable seating badly. It does not cover new physical damage, because a second crack is a second accident. Full terms are on our warranty page.
