My LG tv has suddenly got a problem with the picture. Whilst watching the tv with no problems at all, the picture was suddenly reduced to a thin vertical line down the centre of the screen and an awful smell seemed to come from the tv( much like the smell you get when you switch on an electric fire that hasnt been used for a while and dust has gathered on it Yuk). I immediately unplugged the tv and havent used it since the problem occured yesterday, please can you help
If you have thin horizontal line in the center, sound is ok, your problrem is could be bad capacitors in the VERTICAL section. Check for "bulging caps", vertical IC (for newer model)/vertical Transistors (for older models).

Common LG LCD TV REPAIR - NO PICTURE OR BLACK SCREEN FIX ... came on good with green light working properlybut still no picture.
Back-light problem. Check and replace damaged component/s at its back-light inverter board, or replace this board as card basis. If you wish to get some details; check the site linked here. Surf the site with patience. Pull up older posts. It will be best to replace the inverter board as card basis. http://electronicshelponline.blogspot.com/
That could be the Z board, but most likely the sustain and upper/lower buffer boards. The brightness is found in the Z board. Try to find a repair shop to repair on the component level because the cost of new boards out weighs the cost of replacement.
Hi, Go to the back of the TV and make sure, the component cables are inserted in all the way. Do the same for the source (cable or satellite receiver) component cables should be firmly inserted. Try narrowing the problem by testing the TV with a different source, such as a DVD player if it compatible with the component. If the TV works with the DVD then your TV is fine and the problem goes back to the source (Cable or Satellite Receiver) If the TV still not showing natural colors after been tested with another source.. then, the TV may have a bad PCB.
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.
