Broken laptop screen : what should I do ?

A broken screen affects neither your data nor the rest of the machine. It is a part, and it can be replaced.

That is the first thing to know, because many people replace a perfectly healthy machine for this reason alone. Replacing a panel is a routine job, and usually far cheaper than a new computer.

Recognising the type of damage

  • Star-shaped cracks or spreading black ink blotches: the panel is physically broken. It cannot be repaired, it is replaced.
  • Black screen but the machine is running: not necessarily the panel. See the external screen test below.
  • Image visible but very dark: the backlight or its power supply. The panel itself is intact, but the job still means dismantling.
  • Vertical or coloured lines, a shaking image: often a disconnected or damaged ribbon cable - see lines on the screen.
  • Areas that no longer respond to touch, on a touchscreen model : the touch glass is separate from the panel, and that changes the price.

The test that avoids a pointless repair

Plug an external monitor or a television into the laptop's video output. If the picture appears correctly there, the graphics chip and the motherboard are fine : only the screen assembly is at fault. If the external screen stays black too, the problem is elsewhere and replacing the panel would achieve nothing.

A second useful test for a very dark screen : shine a lamp across the panel at an angle. If you can make out the image, the display works and it is the backlight that has died.

What determines the price

Three factors, in order of weight : the resolution and quality of the panel - a high-resolution or OLED panel costs considerably more than a standard one ; whether it is a touchscreen ; and how it is fixed, since some very thin models have the panel glued to the chassis, which lengthens the job.

On an older entry-level laptop the cost can approach the value of the machine - the one case where replacement genuinely comes into question. See repair or replace.

Carrying on working meanwhile

A laptop with a broken screen is perfectly usable plugged into an external monitor, with a keyboard and a mouse. Many of our customers get through a few days without interruption that way, while the part arrives. Your data, meanwhile, is not at risk at all.

Immediate precautions

Do not press on the damaged area to "see how far it goes" : the ink blotches spread with every press. Avoid closing the lid sharply, and remove any glass fragments carefully. If the screen is cracked enough to let debris into the keyboard, better to switch it off.

The replacement

The job means unclipping the bezel, disconnecting the video ribbon, fitting the new panel and checking the display across its whole surface. It is done in the workshop and generally takes one to two hours once the part is available - it is the supply, which varies by model, that decides the real timescale.

We identify the exact panel reference from your machine's model, order the part and carry out the replacement through a workshop drop-off, in Lyon.

Frequently asked questions

Is my data lost if the screen is broken ?

Not at all. The drive is not involved, and your files stay accessible - including by simply plugging in an external monitor.

Can a crack be repaired without changing the panel ?

No. A panel is a sealed assembly of layers ; a crack cannot be filled and the ink blotch will keep spreading. Replacement is the only answer.

How long does it take to get the part ?

That depends entirely on the model. Common panels are available quickly ; unusual resolutions or recent models can take longer.
