Symptoms
- Visible crack or spiderweb pattern on the glass or panel
- Colored lines, blotches, or dark ink-like spots spreading from the crack
- Area around the crack shows distorted or missing image
- Damage appeared after a drop, impact, or heavy pressure
Likely causes
- CommonPhysical impact cracking the glass or LCD layerA drop, bump, or pressure point breaks the fragile internal layers of an LCD panel.
- CommonLiquid crystal leaking from a cracked panelDark, spreading, ink-like patches are liquid crystal material leaking from the damaged area, which will spread over time.
- PossibleDamage to the backlight layer beneath the glassCracks can also disrupt the backlight, causing dark zones separate from visible cracks.
What to do
- Stop using the monitor as much as possible once you notice spreading discoloration, since pressure or continued use can make it worse.
- Take a clear photo of the damage right away, useful for insurance claims or warranty disputes.
- Check whether the monitor is covered by manufacturer warranty (physical damage is usually excluded) or a separate accidental damage/insurance policy.
- Avoid pressing on the cracked area or attempting to 'push it back into place,' which will worsen the leak.
- Get quotes for panel replacement from a repair shop and compare against the cost of a new monitor, since panel replacement is often not economical on budget or mid-range monitors.
- If insured, file a claim with photos and a description of how the damage occurred.

When to call a pro
