My LG tv (Model number: 32LS3410-UB) has sound, but no picture. When I do the flashlight test I can see a very dark image on the screen. Will replacing the LED driver fix this problem?


If you already tested with the flashlight which is the first step in the blank screen with sound fault then you have to test the LED Backlight supply voltages if you are familiar and good in the electronic repair. First you have to check if bulging capacitors for the LED Backlight drive voltage circuit, replace them. If capacitors are good then you have check the backlight LEDs. The flashlight test proves that the power supply is good and TV is working fine because the sound is ok and picture is fine. Attached videos and links may help you for the repair and replacement of backlight LED strips or LEDs itself depending on the type of LED strips used in your model.

How to fix an lg 47LE5400 tv power lights come on but no picture


If it's a led tv and if you have sound and, also, if you can see the picture with a flashlight very near on the screen in the dark, that means your backlight or your inverter circuit that control the backlight are defect. Good luck,

How do you fix a Samsung 55" Television with no picture but good sound?


The symptoms you described would indicate the backlights are not working.

The 2 main reasons are the backlight inverter board has gone or the backlights have blown!

Since you have replaced the inverter board with a new working one then this would point towards the LED backlights.

Lcd tv has sound no picture


Hi Chad,
Since you are getting the sound, the main board seems ok. Please show a flashlight on the screen, you should be able to see the picture there. If it is so, the backlights in your set are not working. Most LED TVs have LED driver circuit on the power board now days. Here a word of caution, there are two reasons for failed backlights. First the LED driving circuit and second the backlight itself. Which one has in your case, let some TV Tech decide it. In both the conditions your TV should be repairable.
Good luck

I have a Samsung TV model UN50H6350AFXZA which has sound but no picture. Backlights work. Replaced t-con board with new one, but not fixed. What next?


Main board. T con board is only involved with video issues. Main board goes both ways and since you already replaced the T con board that is your only alternative. U got backlite so inverter board is good.

No picture but have sound.


Hi Celeste,
I appreciate your efforts so far.You have sound but no picture. Can you see the backlights? Or is there the on screen LG logo? If the logo is not there it means the backlights in your TV are not working. Mostly it is the inverter board which makes necessary power for the back lights goes bad. Good LUCK.

No picture, sound works good


Sounds like a backlight fault. Dim the lights in the room and turn on the set. Shine a bright flashlight on the screen, you should see a faint picture. If you do, you have a backlight problem

Tv comes on then the screen goes black but can still here sound


This has to do with the voltages supplied to the backlight inverter. There with be 2-3 capacitors needed for the 24v rail which is NEEDED for the backlight inverter to work. Without the backlight inverter you will have no picture and still have sound.

If you are good with electronics you can open the set and replace those capacitors and your 24v rail will be restored. You will then have a picture and sound

My philips lcd tv has sound but no picture what is


change the backlight (cold cathode light) on your monitor.. If you are able to open the back of your lcd monitor carefully, the backlights are located at the upper and the lower part of the edge .. replace it with conventional cold cathode lights(protective tube was removed)... there are also instances that backlight was good but the ballast transformer is burnt. Replace the ballast. Its very cheap to replace that.
