TV Screen Is Black – Powers ON But No Picture – What To Check?

I have an Samsung TV and the screen is black. The TV powers ON but I am unable to see a picture. The TV picture flashes for a second or two and then the screen goes completely black. It is just a black screen with nothing else. I can see the POWER light illuminate so I know the TV is turning ON and staying ON. I do hear sound even though the TV screen is black. My TV is a 65″ 4K SMART LED HDTV and the black screen just started to appear. I am unable to watch TV as the black screen is constant. Does this mean the screen or main panel is bad? If an LED or LEDs go bad, does the picture flash and then the black screen constantly appears? What are some things I can check myself before I call for repair or warranty service?

TV Screen Is Black - Powers ON But No PictureTV Screen Is Black – Powers ON But No Picture

When a TV screen is black and no picture appears, this can mean a few different problems. Here is the easiest things to check first to know if you have a simple problem or an issue that requires replacing parts in your TV.

Black TV Screen Quick Test 1:
First, attempt to get the TV MENU pulled up using the remote control or the MENU button on the TV itself.
If the TV MENU appears, then the issue is coming from one of your sources or components.
Black TV Screen Solution 1:
This would mean that either a CABLE BOX, SAT BOX, COAX CABLE, HDMI CABLE, ETC may not be working properly, something is loose, or needs reset.
-Reset ALL components by unplugging them for 5 minutes including the TV.
-Be sure all COAX CABLES and HDMI CABLES are tight and properly connected.
-If you CAN pull up the TV MENU when you have the black screen, update your TV’s firmware to be sure your TV is up to date and rule out the TV as the problem.
NOTE: If the TV now works and there is no BLACK SCREEN, the issue was either a loose cable, old TV firmware, or a component that needed to be reset and the issue is now resolved.

Black TV Screen Quick Test 2:
Is the component you are using TURNED ON and the TV INPUT is set correctly?
Black TV Screen Solution 2:
For example, if you are using a Roku to watch TV…
-Be sure the ROKU or the component is TURNED ON.
-Be sure you have the TV INPUT set correctly and it is set to the component you are currently using.
-Switch to all the TV INPUTS one at a time to make sure you have the component connected to the correct input.
NOTE: Sometimes inputs are labelled incorrectly and this can cause confusion. If after turning ON the component and changing the TV INPUT, the BLACK SCREEN is gone and the TV works, the issue is now resloved.

Black TV Screen Quick Test 3:
After resetting and making sure the components are connected properly, if you still get the BLACK SCREEN, you may have a bad COAX CABLE or HDMI CABLE.
Black TV Screen Solution 3:
Try using different or new cables for the component you are currently using.
-Use a new COAX CABLE for SAT BOX and CABLE BOX.
-Use a new HDMI CABLE for ROKU, AMAZON, DVD, BLU-RAY, X-BOX, PlayStation, etc.
-Make sure there is no damage where the cables connect into.
NOTE: If after using a new CABLE the BLACK SCREEN is now gone and you can see the picture and sound, the problem is resolved and the issue was a faulty cable.

If the above solutions did not work to fix the BLACK TV SCREEN, see below for other reasons that may be causing the issue.

Other issues that can cause the BLACK SCREEN that will require disassembling your TV and replacing parts:
IMPORTANT NOTE FOR SAFETY – Before disassembling your TV, turn it off, unplug the TV, and wait a few hours so the power the TV holds inside discharges to avoid SHOCK.

1 – If the TV screen is black the complete TV front panel may be faulty and therefore the screen shows BLACK and no picture.
Find out if your screen is faulty or cracked and research to see if a new screen replacement is worth buying vs getting a new TV.

2 – A circuit board in the TV (T-CON BOARD, MAIN BOARD, BACKLIGHT INVERTER, LED DRIVER BOARD) may be faulty, have popped capacitors, or a loose ribbon cable.
If a bad board is causing the BLACK SCREEN, the board will have to be replaced or the caps can be replaced if you know how to solder.
Check the ribbon connections of all boards inside the TV to be sure everything is connected and secure.

3 – If the LED TV flashes on the screen when you FIRST turn it ON and then the BLACK SCREEN is shown, you may have a FAULTY LED or LEDs.
There may be a few LEDs that are not working behind the panel.
FYI – LED replacement is a total breakdown of the TV to replace the strips of LEDs that are faulty.
Check your TV model number and find the manual to see where the LEDs are located and how to replace.

Unplug the TV from the wall outlet.
Wait 10 minutes.
Plug back in and the issue should resolve.

My Tv was working fine yesterday. Tonight I’ve come to put it on. The power light is there but when I turn it on the power light just flashes on and off (until turned off by the mains) but the black screen remains & no sound. If I press buttons on the remote the tv light flickers so it is recognizing it. But nothing comes on the screen?
Any ideas it is an older tv not a smart tv

I have a 49” Haier lcd tv, it was working just fine and then one day we turned it on and there was sound but no picture. I Took the back panel off and wiggled some cords and things, and was able to get the picture to come back. However, every time I turn it off, then the next day I have to repeat the same thing with wiggling cords and blowing on it. Should I replace the T-Con board for that?

I have a 55″ Vizio and when you turn it on the screen is fine. Over time it starts getting a little dark on one side until the whole screen eventually gets a dark cross shaped pattern on the whole screen. If I turn it off and right back on the picture is fine again. Then the problem repeats. I didn’t see this issue referenced yet because my screen isn’t just black. Does anyone have any advice?

I have a 55″ Samsung Curved UHD LED TV with a black screen. When I turn the TV on I see mainly gray shaded vertical lines on the right side of the display for about 1 – 2 seconds then it goes dark. I can see the LED backlighting come on and after about 10 seconds the LED backlighting gets brighter but still no picture. I can hear tones when I change the volume but have not been able to get any HDMI video/audio to work. This TV has had the power, main, and T-Con boards replaced as well as the 4 ribbon cables from the T-Con to the buffer boards, but the issue is still happening. There is voltage to the main and T-Con boards (~12.3 volts) when power is turned on. I have also checked all the connector and wiring continuity between power and LED backlighting connection and power to main, and they are all good. I don’t have a schematic so running out of places to check. Any help would be greatly appreciated.

I have an LG LED t.v. that appears to power on but I have a black screen. A couple of things: 1) When I shine a flash light on the screen, I do not see anything such as a menu 2) I can’t tell if the back lights are on since the t.v. is mounted on the wall; however if there were backlights I would be able to see them in the dark which I don’t see any lights currently 3) there is no volume on the t.v. What to do next?

I have a RCA 39 inch TV with sound but no picture.
I can see the menu with the flashlight test.
I’m troubleshooting the boards and I don’t have 12 volts on the power supply board.
Pushing the on button has no effect.
All the other voltages check out.
Do you think the problem is the power supply board?

Hi I have a Element eleft466 we had a power surge Black screen did the flashlight test we have ghost and sound I turned off the lights in the room I don’t see any backlights what can I do I also have a Seiki 47 inch doing the same thing please help Thanks Lee

When the TV has a black screen, go close to the screen and shine a flashlight on it.
If you see a picture it means the LED lights are the problem.
I noticed that the soldering on the led strip sometimes gets loose, causing the supply cable not to deliver power.
Depending on the type of TV you have, you can either buy a new led strip or attempt to repair, but I recommend buying a new one because fixing one is time consuming you have to dismantle the whole screen unit until you reach the leds.
