1. Defective T-con Board

Your Hisense TV’s T-con board generates vertical and horizontal timing panel signals, enables signals, and provides panel bias in your TV.

The faulty T-con board fails to create and enable the signals, and thus your TV blinks the red light 9 times.

The lousy T-con board also causes your TV’s display distortion, double image, white display, no display, etc. However, your TV’s T-con board goes bad for the following reasons:

  • Power surge
  • Faulty electrolytic capacitors
  • T-con board charging excess power
  • TV overheating
  • T-con board’s damaged internal components
  • Board’s faulty ribbon cables or loose wiring connections
  • Bad contact on T-con board connections


Remove your Hisense TV’s back panel and find the faulty Timing Control (T-con) board. Then check the board and replace it if it is the culprit. The other effective ways to fix your Hisense TV blinking codes are:

  • During a power surge, keep your TV off and install the voltage stabilizer to prevent short circuits.
  • Replace the defective electrolytic capacitor, the T-con board’s lousy connections, and the board’s defective internal components
  • Ensure your TV is not overheating and the T-con board is not charging high power.
  • Check and replace your T-con board’s wiring and ribbon cables. Also, tighten the wiring connections.
  • Avoid plugging your TV and other electrical appliances in a single outlet to prevent TV overheating.

2. Bad LVDS Cable

Your Hisense TV’s LVDS cable transmits the data at very high speeds between your TV’s motherboard and panel by sending a specific voltage. But the faulty LVDS cable fails to transfer data or voltage, and your TV fails to operate.

And thus, your Hisense Smart TV blinks the red light 9 times due to insufficient voltage transmission. However, the LVDS cable goes bad for the following causes:  

  • Faulty LVDS connectors
  • The LVDS cable is getting the wrong voltage
  • Faulty electrical outlet
  • Broken, bent, or melted-out LVDS cable
  • Incorrectly installed cable
  • LVDS cable’s loose connection between the mainboard and TV panel


Your Hisense TV’s differential signaling system is LVDS. Comparing the receiver end’s transmission, this cable transmits two different voltages. But when this cable becomes defective, it fails to send voltage. 

However, to fix these issues, follow the ways below:

  • Replace the faulty, broken, or bent LVDS cable, connectors, & defective electrical outlet
  • Make sure the outlet is providing the correct voltage to the LVDS cable
  • Correctly installed the cable
  • Tighten your TV mainboard and panel’s LVDS cable connection

3. Faulty LCD Panel

Your Hisense TV’s 9 times red light blinking gives the panel malfunction indication. Due to the faulty LCD panel, your Hisense TV won’t turn on, and it will blink codes 9 times and then pause. The causes of panel malfunction are:

  • Damaged or broken panel
  • Broken or stuck pixels
  • Faulty video cable
  • Black spot on the panel
  • The panel was exposed to extreme heat or cold exposure


Check your TV’s LCD panel; if it goes bad, you should replace it. The other ways to get rid of the above difficulties are:

  • Replace the broken panel, faulty video cable, panel with black spot, and panel’s broken or stuck pixels
  • Make sure your Hisense TV panel is not exposed to extreme cold or heat

4. Malfunctioning Main Board

Your Hisense TV’s mainboard malfunction is one of the major reasons why your Hisense TV flashes red light 9 times.

 malfunctioning main board

The mainboard controls your TV’s internal component’s real connection and functioning. However, the motherboard becomes defective for the following reasons:

  • Main board’s worn-out, faulty or broken internal components
  • A power surge or high electricity frequency variation causes a short circuit on board
  • Aged or physically deteriorated board
  • Board is getting insufficient power 
  • Damaged or disconnected power cable
  • Faulty electrical outlet 
  • Warped, swollen, or burnt areas on board
  • Loose wire connection
  • Overheating TV
  • Malfunctioning electrolytic capacitors
  • Blown fuse 


First, reset your Hisense TV to fix the 9 blinking codes. If the red light still flashes, check your TV’s motherboard and replace the faulty board. However, the other easy fixing ways are:

  • Check your Hisense TV motherboard’s faulty internal components and replace the bad ones.
  • Install dynamic voltage stabilizer to reduce high-frequency variation in electricity line and power surge
  • Replace the aged or physically deteriorated board, damaged power cable, board with swollen or burnt areas, blown fuse, malfunctioning wall socket, and defective electrolytic capacitors
  • Ensure the electrical outlet is functioning perfectly and that your TV’s main board has sufficient power.
  • Tighten your TV’s and motherboard’s internal component’s wiring connection
  • Don’t operate your Hisense TV for a longer time. Or avoid plugging your TV in an outlet with other electrical equipment at a time to prevent overheating.

5. Backlight Issue

Your Hisense Smart TV can’t display any picture or video and fails to turn on due to the faulty backlight, and your TV starts blinking the codes 9 times. The cause of backlight malfunction are:

backlight issue
  • Broken, Damaged, or non-functioning backlight 
  • TV’s mainboard is not getting sufficient power due to a defective electrical outlet
  • Malfunctioning backlight inverter 
  • Power surge 
  • Short circuit or circuitry issue 
  • The LED driving circuit is not providing the correct voltage 


Now get rid of these above troubles by following the solutions below:

  • Replace the damaged, broken, or non-functioning backlight, faulty backlight inverter, and bad electrical outlet
  • Make sure your TV’s mainboard is getting sufficient power
  • Install the dynamic voltage stabilizer to prevent the circuit issue, short circuits, and power surge
  • Ensure your TV’s LED driving is providing enough voltage to your TV’s backlight
