  2. Dear shopjimmi, I have an lg37lf66. Well the tv screen went black, so I opened it and found 2 broken condenser in the power supply and 2 in the backlight. I fix this two and the tv started to work for an hour or so. Then the image would flicker and eventually go black. I have found that one of the black chokes in the tcon was not working, infact was very hot and by touching it it would work perfectly.

    After using it for a bit it, the tv made a noise and now the tv is always black ( sound is ok)

  3. Please help me.. I have also a video of the old behaviour, but now is completely black anyway…

    I was thinking to buy a new t-con, but I would like to know if it is the right thing to buy, otr by playing around I have broken something else.

    Thanks you so much in advance

    Simone

  4. @simone cuomo – I would recommend watching our video that shows how to test your TV problem with a flashlight. Testing this will help to reveal whether the issue is the backlight inverter or the main board. Simply go to our channel to find the flashlight test video. I will also send you a youtube message with a link to the video. Thanks and please let us know if you have any further questions!
