If your ONN TV’s standby light is flashing red when you try to power it on, it means the TV’s power board or the mainboard is faulty.
Here’s an overview of the issue:
- Standby light is flashing red: TV is receiving power, but the power board or the mainboard is faulty.
- No standby light: TV isn’t receiving any power. Either the power board is faulty, or the power cord and power outlet are malfunctioning.
- Standby light is on, not flashing: TV is in standby mode and is waiting to turn on. Try pressing the TV’s physical power button several times.
If you are in one of the first two situations, the following troubleshooting method may work.
Here’s how:
- Disconnect the TV from the power outlet.
- Similarly, disconnect all HDMI-connected devices from the TV.
- Now wait for 5 minutes. (Be patient.)
- During this time, press and hold the TV’s power button for about 30 seconds.
- Once done, power the TV back on.
Basically, this is worth a try.
Though you must replace either the power board or the mainboard, often this simple troubleshooting method revives the TV.
If not in your case, contact a professional TV repairer.
That’s it…
