Samsung Galaxy S24 Ultra screen black while the phone is on?
An incoming call or vibration may show that the phone is still operating. We assess the display assembly, connections and board behaviour to establish why the image has stopped.
The fixed £35 diagnostic covers the assessment described below and both-way UK tracked shipping. If you approve the repair quote, the fee is deducted from that quote. No repair work starts without your approval.
Model-specific context
The S24 Ultra uses an AMOLED display
An AMOLED panel has no separate LCD backlight. A black S24 Ultra screen needs checks suited to its panel and display connections. Tell us whether finger touch, S Pen input or an already configured external display appeared to work before the phone became unusable. These functions offer different clues and do not guarantee that the internal display path is healthy.
For the wider fault pattern, read the Phone black-screen diagnosis. If the files matter more than returning the device to daily use, read about data recovery and select Data recovery when booking.
The symptom
Describe the last image and remaining responses
Useful details include:
- The phone rings or vibrates but the screen remains completely black
- Green lines, flicker or a partial image appeared before the display failed
- The problem continued after a replacement screen or an impact
What the diagnostic checks
What we check on your Samsung Galaxy S24 Ultra.
- Establish whether the phone remains powered and starts normally
- Inspect the display assembly and connector for damage or previous-repair issues
- Check board display supplies and signals if the panel findings require further investigation
We’ll explain what we find in writing and quote for the work we can offer. Your options depend on the device’s condition, our test results and the parts available.
Before you post it

Tell us what’s happening with your Samsung Galaxy S24 Ultra. We’ll assess it at our Tyneside lab for £35 and explain your options before you decide on repair.
A screen fault and a board fault need different work
Visible lines or a black panel can arise within the screen assembly itself. We do not assume microsoldering will fix an internally damaged panel. The findings explain which repair or recovery route is viable and its limitations.
Common questions
Samsung Galaxy S24 Ultra black screen FAQ
Can this be repaired as an LCD backlight fault?
The S24 Ultra uses AMOLED. Its dark-screen diagnosis should focus on the appropriate panel, connections and board supplies, rather than an LCD backlight assumption.
Can an external display get my files back?
That depends on device state, unlocking and the configured connection. It is not a guaranteed recovery method. Tell us if an external image already works and whether you can authorise access.
What if the phone does not ring either?
The assessment may need to investigate no power as well as display loss. Describe every response you observed instead of assuming the screen is the only problem.
