No, it's not the LED strips, You have a T-com board problem, so replace the T-com board.

You could have one of three problems. One is really expensing to fix and you might want to trash the set. Thats if the panel is bad. Secondly, it could be a buffer board that went back. Not as expensive as the panel. Finally, it could be the connection between the two. I would first take the back off and locate this board. Undo the ribbon cable and clean it off a bit and put it back. If its still there, you have a deeper problem.

Install the forteManager software that comes with your LG LCD monitor. Go to the Options tab and choose Restore which will set it back to factory settings. For some reason some monitors come this way out of the box and this was the only way I was able to solve the problem with mine.

If the screen works for a short while and then completely fails once the TV warms up you have a problem with the main unit video board or the LCD control logic board. Most often if the picture cuts out but audio continues to work the logic board is over heating and should be replaced. However if the picture cuts out and audio shuts off as well then its your video input board.

Sanyo DP46142 TV comes on for approximately 30 seconds and then screen goes black. Power LED stays on.


Sounds like a backlight problem to me. If you input a signal to the HDMI or Composite input and then it goes black have you tried taking a flashlight to the screen to see if the picture is still there but just dark? That would indicate a backlight issue. That model appears to be an LED edge lit backlight, so if the picture is still there after going black your going to have to trace out the backlight circuit and see whats going on. Usually with LED backlighting if it comes on at all then the LED's are good, its just the driver supply thats failing to keep them on. Some TV's have a small separate board that provides the backlight control, but i suspect with this model its on the power supply board and not the motherboard. Have you checked that board? It could be bad caps on the power supply board, check the voltages to the backlighting when it lights up and then when it goes dark. It could just be some failed capacitors on the power supply causing that voltage rail to drop off.

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,

The most likely problem is the Backlight Inverter. It supplies the power to the LED array which illuminates the screen. If you are brave and also technically able, it can be replaced at home. Here is a video to help. LCD TV Repair Tutorial How to Replace the Backlight Inverter Board in LG...

What is the likely cause of the left half of a led tv being dark compared to the right half? The pictures is there but it seems the backlight has gone out.


Hi Mike,
It has to be the backlight then. It can be repaired, but opening the LED panel is quite tricky and risky job.
Good Luck.

How do I get the picture back on my LG LED 50 flat screen? Sound works, no picture.


-You have a bad panel. Led arrays internal to the panel are defective. Replacement cost exceeds economical repair.

How do I know if my backlight on my LG tv is working


Wait until it is very dark. All lights out. Switch on. The screen should perceptibly change from black to dark grey. Perhaps you will see some light leakage near the edges where glass meets plinth.

And there is the T test where you touch the screen with the back of your hand after it's been on for a while. Although LED backlights are cold, they do generate some heat. So a perceptible change in temperature usually indicates that the backlight is functional.
