You most likely have a bad lcd panel drive board.We have seen on occasion the cable between the panel(top side) and the main circut board has come un-plugged.Hope this helps.

What can cause an LG 47LN5700-UH TV not to turn on or respond to the panel buttons or remote control?


TV in totally unresponsive in many if not all areas. Only thing they all have in common is the set's power supply. They are big culprits.

Check the board for burnt rsisitors, diodes, bulging capacitors.

I have a sony bravia kdl-37v5810. sound on loud no picture buttons dont work on set or remote have to unplug to switch off.


Two pieces of information:

First thing to try is unplug the set and a box or receiver if you use them for several minutes from power, then plug things back for power and see if that helps.

Second, Sony is one of the few companies who uses the same access code to reset all their sets for the last 20 years, if it comes on and responds to the Sony original remote you can try that,

set is off, Then with the remote Display, 5, volume up, and power.

If set comes on you should be in the service menu---do not by accident touch any buttons randomly : what you want to touch is 8 (reset or write should appear on the screen in red, then hit enter and the word should change to green and the set shut off.

turn back on with remote and see what happened or not.

I had sound but no picture on my Element Electronic FLX 3211B LCD Television Set. I replaced two capacitors, and now I have lit screen by turning on the tv on the side panel. Remote does not control the tv...


You might have bad capacitors still that you cannot see. The only way to be sure is with an ESR meter. Check all the connections on the boards again to be sure that the sensor for the remote did not come off.

Try several inputs. See if you have the sam result. If you are watching with an antenna make sure all is connected and setup is set up.

No Picture, No Sound While Watching


Resetting the TV
If the buttons on the remote AND the buttons on the TV case do not work (channels do not change and you cannot open or navigate the menu), the TV has stopped responding. Reset the TV as follows:

NOTE:
Some TVs have a reset button. If available and accessible, try using the reset buttons before using the steps below. Using the reset buttons can save time.
1. Unplug the TV power cord from the power outlet.
2. Unplug any connected devices (DVD, Set-top boxes, etc...)
3. Press and hold the TV power button for five seconds.
4. Plug the TV power cord back into the power outlet and turn on the TV.
5. Open the on-screen menu to confirm that the TV is responding again.
6. Turn off the TV and reconnect the devices.
7. Turn on the TV.
