TRANSCRIPT
Here's a plot twist-often, your TV picture will go out before the sound does, preempting your show with an unwelcome cliffhanger. Hi, I'm Paul Blake for Repair.com with some steps to ease you through TV picture loss-from prevention to recognition to next steps when your picture finally does go out.
Step 1: Avoid overheating your TV
The lamp inside your TV is responsible for projecting colors and images onto the screen. So frequent overheating not only shortens the lamp life, but your TV picture life as well. To prevent overheating, keep your backlight system well ventilated and avoid turning your TV on and off repeatedly without allowing it time to cool down in between.
Step 2: Watch for warning signs
The fluorescent bulb in your LCD TV dims over time. If you start to notice your picture getting progressively dimmer, take it as a fair warning that your LCD's backlight is just about ready to quit.
Many DLP TVs have a lamp icon on the TV frame. When you see a light turn on above the icon, that's a sure indication that your backlight lamp's days are numbered.
Step 3: Reboot your receiver
If your picture does quit, first make sure that it's not just your receiver acting up. Reboot it by turning off your TV and unplugging the receiver. Wait about 10 seconds before you reconnect the receiver, then restore power to it and your TV. If that doesn't work, the issue is likely with the TV's lamp.
Step 4: Investigate your picture failure
For DLP TVs, picture loss can involve lamp failure. No lamp, no images. The other point of failure could be the ballast, which starts up the lamp and keeps it powered. Determining whether your issue is with the lamp or ballast can be tricky without professional help, but if you recently replaced the lamp, the ballast is likely at fault.
For LCD TVs, a failed backlight bulb or inverter could be the culprit. If the problem lies with the inverter, your functioning backlight bulb won't receive power. A good way to rule out one or the other is to get the room as dark as possible and shine a flashlight at the TV from an angle. If you can see images, then the problem is the inverter. If not, then it's likely the backlight bulb.
Step 5: Decide to repair or replace
If you are not ready to part with your DLP TV, you can have the lamp or ballast replaced. LCD inverters can be replaced, but replacement LCD backlights are not generally available, so buying a new TV may be your only option if it fails. In any situation, consider the TV's age and deals on new TVs before deciding.

I had my TV for almost a week and the image disappeared only on HD. The unplug and plug again thing worked! Saved me, thanks
THIS is why I love RUclips so much. Thank you for this quick and most effective tutorial. Now I can continue watching my programs!
Absolutely the BEST ever advice spoken clearly and without non essential background music. SO VERY HELPFUL. THANK YOU KINDLY
It does work! I unplugged my 📺 for 30 seconds, 🔌 it back in and my screen returned.
Thank you!!

After watching this video, we were able to diagnose the problem and fix an LCD tv. Thank you!
This might be different than this video.... but -
We almost went the route of baking the module, but I came across a post that said to turn off the TV and the set-top box, remove the power source for at least 15 minutes for both, discharge the power button by pressing it and leaving it alone. After 15 min approximately, I replugged both the set-top box and the TV into the electricity socket. Turned on both STB & TV. I believe ATT U-verse had to cycle through... then voilà, the sound was back! This happened a second time and I went through the same process, and again it worked! So glad I didn't bake the module.
Thank you! I unplugged my tv for 10 seconds and plugged everything back in and it worked!
Thank you.Knowing whats wrong makes me feel better.
I unplugged it for 10 seconds and it worked, thank you it was really helpful

Well, then, you don't have the same [small] problem as these guys; your problem is a bigger problem that needs additional diagnosis, and may not be easily fixed.

Had recycling pick up the TV. Seems as though these Smart TV's don't last very long.

OK TV Guru's
I have a LG 42LB5600,
I can see with the flash light a picture on a dark screen, I can't see any lights coming thru the vent holes or with the back off. Solid sheet of metal all over and fastened tightly to the screen. Would this be the power inverter board, T-Con or backlight, Thank you in advance for any positive input.
Just like that all hope is gone ....I need a new TV...
Thanks for that!
That really was truly clear informative.
Ok..🤞🏼

Very useful indeed how do I get my hand on an inverter as I shined a light on the screen and still had picture but from a far it's just black
These techniques still useful in 2021😀
OMG! I've never posted a comment but I had to! Unplugged the tv AND IT WORKED!! THANK YOU!!
Sorry but did you not fucking try that before looking it up? You bellend.
I'm grateful watching you great job
Thank you! I unplugged the cable box for 5 minutes.... Viola picture is back!

Thank you so much you just helped me out,Ty
The thing that makes me mad is that I haven't had my tv for a whole year proper yet goddamn....
They don't make things last long I was lucky to lived back in the days when stuff was well built to last I had a problem with my refrigerator had to get a new one
After only a few years now looks like the same thing with the tv I think everything run by computer is a curse lol back in the days before computer we did not have problems with cars refrigerators and TVs like today
Thank you so much ! It worked . Thanks !
Hello, watch your video, but what my TV Element 52 in does is the pic and sound works as soon as you turn it on, in about 5 min the pic goes out but you can still hear the sound. Do u know what the problem could be.
Thank you, Annette
Plasma TVs weren't mentioned here. Do any of these tips apply to a plasma set? or is it always the panel with plasma and no picture? I have a 42" plasma for my main set. It's 5 years old and working great. Just wanted to find out if any of this it applies as well.
You are a genius and I thank you.
My tv (LG) comes on: at first it would bring up both picture and sound for a few seconds, then screen grow black but sound still on. I tried all the rebooting methods but tv progressed to loss of sound as well as picture: now it comes on when I try to reboot only with picture and no sound, but screen goes black within about 10 seconds and I have neither. Given cost of repairs I’m wondering whether it’s worth keeping. too bad as is 60 inch lg that cost about 2 grand new. Now only 3 yrs. and little more older. With prices of tv down I’m thinking of a 50” much more affordable new may be best bet.
How common is it for the picture to go blank on flat screen TVs while maintaining the sound? I've never seen this with the older big TVs.
Very helpful
I have to grab myself a brand new tv since my 2 year old tv is done for
Thank you, it worked!
I had the same problem on my LG because my remote control batteries were weak. Interesting the sound came through from the receiver.
I have the polaroid model tla-04641c from Walmart. I used to be able to shake (lol) the tv to get rid of the distortion (which started happening this year after having the tv for 3 years) there were lines and dark areas. But now when I turn on the tv there only sound no picture. I plug out the cable box and sometimes the picture comes back, but then it blacks out after a few minutes :( have to junk it.
thank you very much this guide fixed my TV quickly

Hi I have a LC-37D43U tv. The power works with green light in front of the tv and the backlight also work. When I turn on the power there is no picture but I have a glow. The audio also works well and can hear everything clear. The tv control, by pressing any function does not work. Also with the flashlight it does not show anything. I did open the back of the tv and would like to try to fix it myself before giving up and buying a new one. What should I do or try to verify as the problem?? Do you have a video explaining what to change or test before?? Thank you. Frank Bilotto

I have an LG 55UM6910PUC it just shows blue/green screen. When it first happened there was audio and you could switch channels but no picture. Now there is no audio so I can't tell if the channels are changing with the Remote.
I had the oddest thing occur. The power cord was only plugged in half way. I got sound but no picture. Could the power cord not being in all the way produce sound but no picture? I'll keep investigating to make sure it is working 100%.
Have a Toshiba TV model # 50L 1350UC manufactured Nov. 2013. Seems the inverter needs replacing, but can't seem to find any tutorials on this set? Also, model # seems to be non existent ? Can anyone help with this?? Maple Ridge, B.C. Canada
