Hello Jon,

Check the power board.

I have the same trouble with my LG M2762D-PC 27" television.

Seems to be one bad ceramic capacitor.

See my topic What value are these LCD TV LG M2762D-PC capacitors?

Have you already opened the TV?

Good luck in repairing.

Greetz, Pierre.

ctruman72,

I don't know which model you have but if you hold a flashlight to the screen do you see movement and images? If you do the backlight has failed. If you do not see images you may have a main control board problem. Did the service tech tell you which board? You may find the board on the internet. Use the tv make and model along with the board part number with a google search.

How do I fix the blacklight?

Hi Darlene,

How did you diagnosed the error? If you hold a flashlight to the screen, do you seen any pictures?

by

As stated above if you hold a light to it and you still see pictures you have a bad backlight inverter (think of it as a starter for the old style floresent lights.

As stated above just find model and serial # and google parts there are several online places that offer boards inverters ECT.

Just fyi if ya find bad capacitor or such I usually go up by 5 so that's just my 2 cents

by

I have never had a broken TV before--LCD or any other type. But the flashlight diagnosis worked--I could see the images. Thank you--I'll look into that rather than replacing it or making an expensive repair call.

I have a 65" LG, OLED, 4K Ultra HD, Smart TV. I have had this TV for 1 month. The screen just went blank / black but everything else was working on it.... sound, apps pages, etc. but I could not get a video or satellite image at all. I decided to try resetting the TV to it's original setting and it worked. I have a picture again. It is a complete pain as I now have to go back and set everything up again. But at least I can watch the TV again. Hope this helps some or all of you!!!

How do you reset the settings if you can't see anything on screen? Is there a manual reset that can be accessed through the control buttons? What is the process used to access the manual reset?

by

When my TV does this I can only "not see" a broadcast picture but everything else shows up. I just click on my remote to open up settings on my tv. That all shows up. I have had to reset my TV 2 times now to get the picture back. The last time I had it happen, I did not have time to mess with it so I just turned it off. The next morning when I turned the TV back on it was all working again,

This sort of makes me wonder if maybe something in the TV is over heating causing the problem??? Once it has time to cool down it goes back to working as normal??? I have no clue. But, the screen has gone black for video, satellite or broadcast on 3 different occasions not and I have been able to get it back each time.

D. Mark French, if you are having the same problem I am.... You should still be able to use your remote to navigate thru you settings for the TV...... If not, I am sorry and wish you luck!! This is all so frustrating!

I wish you luck. I had it happen to my 55" and then to my 70" LG. Both were one month past warranty and it's the $1500 part that needs replaced. My LG repairman called the company and fought with them to cover the costs. After about a 20 minute screaming session they finally agreed. This part will go out on all these TV's before they should according to the LG repairman. So good luck

More than likely you have 1 or more LED's that are shorted out. When this happens the LED strip will draw too many amps and the board will shut down all LED lights as an over-amp precaution. This happened to my 50" LG and I was able to fix it at no cost by removing that particular LED strip from the circuit. It is not a difficult repair, but does require someone to pretty much completely disassemble the TV. If you want to attempt the repair, here is a Youtube video that provides some instructions,

You can replace the strip that is bad for about $50 or just remove it from the circuit. If you just have one bad strip, you probably won't notice any change in picture quality after it is removed. Be careful if you disassemble the TV. Even if it is unplugged it will still have capacitors that carry a high charge of voltage.

It's the led backlight has gone bad. Company will ask to change the entire panel assembly , for huge amount of money. Or ask to buy a Annual maintenance contract. Still expensive. Simply go to AliExpress website, buy led backlight bars and replace them. Or u can also buy individual LEDs there, and reflow/hot air solder it yourself. Search for LG Innotek LEDs.
