Question about LG Televison & Video

1 Answer


I have an LG 42LN5300-UB BUSDLMR TV and I have no picture and no backlight. I am considering getting a 3 board kit to try to fix the problem. What are the chances that the 3 boards will fix the problem? After the 3 boards, are the panel components very low risk of failure?

If you power on your TV but you do not see the menu options, or any video display - just a black, blank screen, and possibly no audio as well; try the recommended steps below to resolve the issue. Check if the status LED, in front of your TV is ON. ... To confirm, point the TCL remote towards the TV and press any button.

I have a 60 Inch LG Plasma TV Model Number 60PV400-UB I have sound, Remote chances channels and can tell volume is still working but have no picture.. Just Black Screen

The most likely case is that the 'backlight' has failed.
If you turn-off all the lights at night, you can generally see the feint picture generated by the screen. If you can see the picture it means the backlight has failed. You might be able to get the backlight replaced.
If you can't see the feint images, either the hardware to generate the images has failed or the LCD screen itself has failed.
Unless it's under some kind of warranty you'd need to get a repair quote for it. But if the LCD screen itself has failed, it'll essentially be uneconomic to repair.
Best of luck

I have a TV that shows power on (red light on front of TV), but nothing on scree. TV model is LG 42LN5300-UB

Check the various voltages coming from the power supply board and see if they are all ok, there is a legend on the power supply board to show what voltages are at what pins on the connectors,the 5 volt standby we know is good as long as the set has sound, but check the others

No picture on LCD tv but sound works!

Yes, i would get it checked first to make sure it is the backlight, if you can see a slight glow around the edges then the backlight is working.
