Phone won't turn on at all?
A phone that shows nothing at all isn't always dead. Sometimes it's a fully drained battery, a frozen system or a broken screen on a phone that's actually running.

Signs you may notice
- Nothing happens when you press the power button
- No charging sign when plugged in
- Phone vibrates or rings but the screen is black
- Phone turns on only while connected to a charger
Safe checks to try first
- Charge it for at least 30 minutes with a charger and cable you know work.
- Force-restart it. On most Android phones, hold Power and Volume Down for 10–20 seconds. On iPhone 8 and later, press Volume Up, then Volume Down, then hold the side button.
- Call the phone from another number. If it rings or vibrates, the phone is on and the screen is probably the fault.
- Plug it into a computer and see whether it's detected.
Stop and bring it in if…
- The phone is hot, swollen or smells of burning
- It stopped working after getting wet, so don't keep charging it
- You need the data and the phone shows no sign of life (avoid repeated attempts)
What usually causes it
One symptom can have several causes. These are the most common ones.
Fully drained or failed battery
A deeply drained or worn-out battery may not start the phone.
Broken display
The phone is running but the screen shows nothing.
Power button or charging fault
The phone can't be switched on or charged.
Software crash
A frozen system that a force-restart or software repair can fix.
Main board fault
A short circuit or failed power component, often after liquid or impact.
What our technicians do
We connect the phone to a bench power supply to see how much current it draws. That quickly separates a dead battery, a display fault and a board-level short circuit. Board faults are traced and repaired under the microscope where possible, and if your data matters most, we tell you whether recovery is realistic.

Can you get my photos back from a phone that won't turn on?
Sometimes. If the main board can be repaired enough to start, data can often be recovered. We'll tell you how likely that is after diagnosis.
