TV with Black Blank Screen Repair How to Troubleshoot Symptoms for a Faster Repair

TV Repair Help for a TV With a Black No Image on the Screen

This video is designed to help you better understand the symptoms that your TV is showing and to also help you when gathering information and troubleshooting, when seeking help for your TV repair.
When troubleshooting, be sure to ask the following questions, and take notes as you are observing the symptoms.
We will now go over some common symptoms that TVs can show and what we should look for in greater detail with these symptoms.
Does the TV power on?
Different TV models, can show that they have powered on in different ways. Some TVs will show a standby light, when the TV is not powered on, then after powering on the TV, the standby light is no longer lit up.
On other TVs, the standby light will change colors once the TV is powered on. For example, a TV could show that the LED light is red, when in standby mode, and then once powered on, the light turns to green.
Do you have sound?
Have you tested your source video to be sure it is not the problem?
For example if you are not getting any video on the screen through HDMI one, have you tried a few different sources, maybe a different blu-ray player, cable box, or any other source?
Have you tried running a flashlight test? Here is the link for a tutorial on how to do a flashlight test.
Is the screen always black or do you get a picture for a moment and then the screen goes black?
Does the screen fade to black? Or does it go black immediately?
Can you pull up the menu on your TV screen?

Hi, I have a model 47LA6200 LG 3D tv and it powers up and has audio but just a quick flash of video and then black screen. I checked the power board #EAX64905501(2.3) and no voltage out to leds (even with connector removed). I found a guaranteed used board on eBay and have it on order. I see you likely have repair parts too. Question is, from what I do deduct the led voltage supply is bad, but what are the chances one or more led's are bad too? Something I saw on your page said this power board is many times associated with bad led/s. TV is several years old - do you recommend I replace the leds while I have the TV partially apart and do you stock them (sets?).

First check to see for sure that you don;t see images on the screen use a flash light. If it shows an image and has sound then it is the controller board. Make sure that your power cable is connected and if you see the standby light. If it is total darkness and no standby light or sound at all then it is the main board. Hope this helps I know it is very frustrating. If you are not technical inclined then I suggest let an expert fix it.
Good Luck everyone!
Heidy

Hello I just found this video and it helped explain so much I was wondering if you may be able to help me with an issue I am having with my living room Tv. It is an LG 42CS570 when powered on in the morning after being off throughout the night it will display the LG start up screen it will then slowly start to fade while 1 inch of full picture (left to right horizontally) will appear at the top of the screen the lower will still be fading from the LG logo from start up after approx. 1 hour of being left on it will display full picture as if nothing is wrong. No further issues until the Tv is powered back off and allowed to cool down a bit or if the air around the TV becomes too cold while in use it will start glitching picture usually lower than 70 degrees or so. Any help would be greatly appreciated.

Thank You I pulled every plug out and plugged them back in and my Black screen went away and I had sound. Thanks for giving me the courage to fix it myself. I don’t know if it will last but for now I am a happy Lady!

Hi there, I have an issue with a lg tv, model no lg42ld690. I used to get these horizontal lines across the screen but when it warmed up, the picture would go back to normal. I unplugged and replugged the two ribbon cables that go from the main board and into the to frame, and now it is just showing a blank screen. Audio is fine. Backlights work. Power is ok. What do you think it might be? I can't see any blown capacitors. The flashlight test fails also.

The tv has power and comes on with sound. There's this little underlight that comes on where you can clearly tell the tv is on but the screen never shows a picture. It stays black. There's a small sliver of light in the bottom right corner that would indicate that the screen may be damaged. Any info on what to do would be extremely helpful

Hi Jimmy,

I have an issue with my Samsung tv which is connected to a BT TV cable box. Intermittently the screen will go black with no sound and come back on around 20 seconds later. More recently on occasion it goes black and I need to go to the guide, change channel and then go back to the original channel to get it back. I disconnected the TV from the cable box onto terrestrial TV and all was fine for a couple of days. Reconnected it and immediately had the issue again. I am guessing (perhaps wrongly) this this is more likely an issue with the cable box?

I fixed my moms tv that had the no video signal problem. I did 2 things: 1. A factory reset. 2. Unplugged and plugged the 3 black, red and yellow cords on the back of the tv. Before unplugging the cords though, I had the no image with sound problem so that is how to fix the no image with sound problem. I'm currently watching tv right now on the tv that had the no video signal problem before. I fixed that just tonight. If you have the exact same problem I had, try the two things mentioned in this comment.

Hi! I have an CHANGHONG LED50YC2000UA that boot up and the logo of the company is shown normally at start up then BAM, blank screen with backlights on. Could you help me identify my defect board? I think it is the mainboard as I heard the EEPROM on that model could be bad on a really old post elsewhere

[akitaaberdeen]

Thank you I just put the HDMI cable in a different Port that did the trick thank you

[wilvelas]

Hey you have some great advice here, now I'm just hoping to pick your brains. I have an RCA 65" 4K TV (Model RCA PRK65A65RQ). The screen won't come on. I can see the back light turning on, can't see any menus or image, have tried hooking up different sources (even tested the sources with another TV installed in the same location to make sure they were working), have tried running the flashlight over it and am not getting anything. Any ideas? Thanks in advance.

[brycen]

Ok I hit my tv there’s a crack in it I can still hear sound what can I do to fix it if possible

[gurnamdulku]

Hi Jimmy, i have this RCA Model RTRU 5828-CA_W. The screen light turns on( that means led backlights are working) but no image or audio.
