Won't Turn On

Samsung Smart TV

Severity: Critical

What Does This Error Mean?

A Samsung TV that won't turn on has no picture, no LED light, or no response to the remote or power button. This can be a dead remote battery, a bad power cable, a power supply fault, or a failed main board. Start with the simplest checks — remote batteries and power cable — before assuming a hardware fault.

Affected Models

  • Samsung QLED Q80B
  • Samsung QLED Q70A
  • Samsung Crystal UHD AU8000
  • Samsung The Frame
  • Samsung Neo QLED QN90B

Common Causes

  • Remote control batteries are dead or the remote has failed
  • Power cable is loose or the wall outlet has no power
  • The TV is in an unresponsive standby state
  • Power supply board has failed and is not delivering voltage to the TV
  • Main board fault — TV receives power but cannot complete its startup sequence

How to Fix It

  1. Replace the remote batteries with fresh AA or AAA batteries and try powering on again.

    Dead batteries are the most common cause of a TV appearing unresponsive.

  2. Press the physical power button on the TV itself (usually on the back or bottom bezel).

    If the TV turns on with the physical button, the remote is the problem — not the TV.

  3. Unplug the TV power cable from the wall, wait 60 seconds, then plug it back in.

    This drains residual charge and clears a frozen standby state.

  4. Test the wall outlet with another device (a lamp or phone charger) to confirm it has power.

    A tripped breaker or dead outlet is easily overlooked.

  5. Check the standby light on the TV. If the red/amber LED is on but the TV will not turn on, press and hold the physical power button for 10 seconds.

    A lit standby LED with no response means the TV has power but the startup is blocked — a hold-reset often clears it.

  6. If none of the above work, contact Samsung support or a TV repair technician.

    At this point the fault is almost certainly hardware — power board or main board.

When to Call a Professional

If the TV shows no standby LED and does not respond to the physical power button, the power board has likely failed. A technician can replace the power board for $100–$300 depending on the model. Main board failures are more expensive — get a repair quote before committing, as it may exceed the TV's value.

Frequently Asked Questions

My Samsung TV has a red light but won't turn on — what does that mean?

The red standby light means the TV is receiving power but stuck in standby mode. Try pressing and holding the physical power button on the TV for 10 seconds. If it still won't turn on, unplug for 60 seconds and try again — this drains the standby capacitors.

Can a power surge stop a Samsung TV from turning on?

Yes — a power surge can damage the power supply board or blow internal fuses. If you had a storm or power outage recently, this is a likely cause. A qualified technician can check and replace the power board if surge damage is confirmed.

How do I know if the Samsung TV remote is broken or if the TV itself won't turn on?

Try the physical power button on the TV itself — it works without the remote. Alternatively, use the SmartThings app on your phone as a remote control. If the TV responds to the physical button or app but not the remote, replace the remote.
