Insignia TV Won’t Turn On No Red Light [7 Easy Solutions]

Your Insignia TV fails to turn on, and no red light on its front means your TV has no power. The major causes for it and their quick solutions are: 

1. Faulty Power Supply Source

The defective power outlet is one of the main culprits for which your Insignia TV won’t turn on with no red light.

The faulty outlet stops supplying power or voltage to your TV, and your TV fails to start and operate. The wall outlet becomes malfunctioning mainly for the following reasons: 

  • Damaged, broken, or worn-out power supply unit itself 
  • Loose or faulty cable connection 
  • Board’s bad, or damaged wiring 
  • Tripping circuit breaker 
  • A power surge or short circuit 


Your Insignia TV stops turning on, and there is no red light lit on the unit means power is not reaching your TV.

Thus you need to check and replace your bad wall socket, which is not supplying power to your TV. The other effective solutions to overcome the above troubles are: 

  • Replace the physically damaged or worn out outlet, faulty or damaged cable, tripping circuit breaker 
  • Check and tighten the wall outlet’s internal wiring connection 
  • Install dynamic voltage stabilizer to prevent short circuits and power surge

2. Defective Main Board

Your Insignia TV’s motherboard captures both the analog and video signals and then transforms these into a digital signal.

The T-con board receives a digital signal from the main board and then projects it on your Insignia TV screen.

But the faulty main board can’t perform all these functions, and your TV doesn’t get the signal to operate, and thus your TV won’t turn on. Your TV’s motherboard becomes defective for the following reasons: 

  • A power surge or short circuit 
  • Board’s defective or broken internal components and faulty internal wiring 
  • Aged, worn-out, or physically deteriorated board
  • The motherboard is not getting adequate electricity or drawing excessive power 
  • TV overheating 
  • Blown fuse 
  • Bad resistors 
  • Faulty wall outlet 
  • Disconnected power cable or loose cable connection 
  • Warped, swollen, or burnt areas on board
  • Faulty electrolytic capacitors


Remove your Insignia TV’s back part and check whether it is malfunctioning or not. If the board doesn’t respond, you should replace the board. The other quick ways to fix the above troubles are: 

  • Install a dynamic voltage stabilizer in your home to prevent sudden power surges and short circuits. And during voltage variation, keep your TV off. 
  • Check the motherboard’s internal components and replace the bad ones. 
  • Replace the blown fuse, physically deteriorated board, lousy resistors, malfunctioning wall outlet, and defective electrolytic capacitors 
  • Don’t operate your TV for a long time. Or avoid plugging your TV and other electrical equipment in a single outlet to prevent your TV’s overheating. 
  • Tighten your TV’s power cable connection 
  • Ensure your TV’s main board is getting sufficient power and not charging high power. 

3. Non-Functioning Remote

Due to your TV remote malfunction, your Insignia fire TV won’t turn on. The Remote sends a signal to your TV, and your TV turns on by receiving that command.

But the faulty remote fails to send the signal, and your TV will also not respond to it.
