Question about LG Televison & Video

1 Answer

When I turn on the tv, I get no audio for about 10 minutes and the the picture never comes on. I used the LG online chat and they showed me how to manually reset by unplugging tv, pressing power button for 10 seconds and then replugging tv into the outlet. It worked but the next day, I had the same problem all over again. No picture but audio after about 10 minutes. Can you help?

What is causing LG TV 47LN5200 to lose picture and go and stay black at random time intervals?


you seem to have a reasonable knowledge of the problem
it is unfortunate that you still have a problem but the fact is, replacing parts without fixing the original fault will only cause the replaced parts to fail again
it is a good project and will improve your knowledge well past the point where a new tv would have been cheaper
there are manual on the net that you can buy /download that may help and they may show an area not considered that is the original fault

The red light turns on but no picture comes on


Get real close to screen and maybe use a flash light to shine on the screen and see if you can see the picture still, it will be dark and almost not visible but you should notice something move. If your screen has picture then you most likely have a back light problem. Most common problems are bad inverters, or the inverter controller card. possibly a bad power supply but most likely inverters, test each circuit, replace as needed.

You probably need a audio cable that runs from the pc audio out to the TV audio in. Radio shack has them so do a lot of hardware store and best buy.

Audio cuts out


HDMI is not a universal standard. Some units will not talk back and forth correctly and can cause lock ups, loss of audio or loss of picture. Try switching to component inputs and see if it works better. Check your owners manual but I believe the component inputs will also accept 1080P as long as the Panasonic Blu Ray can output 1080P. Don't believe what the Salesman said if he told you that you have to use HDMI or you won't get HD.
