Many thanks. I am down to Power or backlights.. question if plug or unplug the mains I see the backlight flash for a brief moment. No voltage on the LED+ and LED-.

Thanks so much for this Problem solving video. Incredible

My TV screen turns on fully for 5 seconds after turning it on, and then the backlights turn off. Ive tried many things and this is consistantly happening, so the backlights clearly work but are constnatly being turned off shortly after powering on? Do you know if this is a specific problem?

Very useful tutorial, thanks for sharing

Yes! I have a bscklight issue with my tv. I see the faint images and colours when I use a flashlight. Will be calling the technician tomorrow

Hear the tv turn on the red light blinks not seeing any faint images but one time it did come on and went out starting from the top to bottom

My LG 65uh950v starts fine, works for 30ish minutes, and then goes black, but sound still works. Tried the power off, for hours without live socket. I only use the telly with WiFi, so nothing is connected. Nothing appears on the screen no matter what I do, but I can turn TV off. There is a small red light blinking on one of the circuit boards, that only blinks after it goes black. +2000£ TV and only 6 years old. Hate sending TV to repairs, without knowing the issue since fault checking is a costly potential rabbit hole. I got 200km to repair shop one way so that's why I really would like to know more first. Tom in Norway Any ideas?

Is it possible to have an intermittent backlight failure? Have to try turning on my tv about 50 times. Sometimes can see a faint outline. But if I try enough times it fires up and works fine

I tried flash light I can lightly see the tv option ...so is it black light issue ....how can we fix it ourself

Thanks for your help I did the Ezy stuff no good thanks for your help

My tv if i turned it off and went to sleep , the next day i turned it on the display has no backlight for 30 minutes or more , and then the backlight comeback, i have to wait 30 minutes every day to get it to work . Any ideas?

Interesring issue where the back light powers on for about half a second when the tv is switched on. Removed the ribbon between the main board and power board and nothing. Metering 5v momenterily across the backlight output then sits at 2.5v. Assuming its the power board, but the fault is the output voltage, with the main board disconnected youd still expect the the light to behave in the same way, bur it only momentarily lights with the main board connected. Any thoughts appreciated!!

I have a Telefunnken 40FHD tv it have faint pictures and have sound can you help me

I put the flashlight Infront of my tv then I can see the clear what must I do know

I’ve got LG Sony LED TV. There’s sound, but screen just went black after I watched KZfaq for approx 15mins. There is a white/grey line at top of screen. So I’m guessing my TV is bust ? I can’t see any images with a torch ?

Tysm matee!! You sound cute btw 😅😊

This is so annoying i left my house for an hour came back and i thought my tv was off my Xbox was still on and i tried grabbing the remote and turning it on and hmmmm still dark and i heard the off chime when i hit the power button so then i got confused like hmmmm it was already in i turn it back on get a quick hdmi 3 flash in the corner of the screen perfect sound no picture i unplugged it unplugged the hdmi tried it again and still no progress so i moved it to my living room to get another power source and same thing so I’m like greeeeeeaaaaaaaat it’s ruined I’ve had this tv so many years now and it’s been in my room at my moms house i bring it to my house for 2 days and boom it goes out 😢

my lg android tv 65 inch. only audio, no picture appear on screen.

My lg tv works but after i pit on a Netflix video it Black screens after a few minutes

L G T V colour screen problem no byeing

what if the backlight works for a couple of minutes, then it blacks out ? if i leave it for a couple of hours, and power it back on, it works again only for a few minutes, then off goes the backlight. any idea which component could cause this issue?

My tv comes on for a a second or 2 then goes black is this the same problem I tryed the first one but nothing stays normal for about 5 seconds then goes black

meh... I have a 2021 LG LCD TV and the backlight is fine, the power board is fine, and I can change channels and hear sound but no picture, it's completely dark. I am fairly certain that after 2021 they stopped using T-CON (converter) boards as mine does not have one, so the only culprit here is a bad LCD or a bad controller board.

This is now my second tv that has done this. It's seems to be a common thing. How frigging annoying and a rip off

Try tapping gently on the back of the tv.

THIS HAPPENED RIGHT BEFORE THE EOURS MATCH SOO ANGRY RN
