LG 15Q9AG TELEVISION

Fix audio damage.

One day I had to fix the television model LG 15Q9AG with audio damage.
The symptoms are:

  • When the temperature of the engine warmed up, the audio comes out the stronger and the volume does not work 
  • There are times when no audio out. 
Many technicians are fooled by replacing the glow Processing IC OICTMSA003F but the actual damage does not occur in the IC. Damage actually occurs in audio driver IC that is LV1116N, because if the IC is the temperature starts to rise then the audio comes out to be defective.

If you've replaced the IC but the audio is still experiencing the same symptoms, then you must install resistors on the IC working voltage of 100 ohms to 220 ohms.

Looks very easy, is not .. Actually if you have never experienced repair damage like this, will not be as easy as it seems. That's why experience is the best teacher for us and most expensive things that are not easy to find.
