It possibly could also be the capacitors https://www.ebay.co.uk/itm/LG-37LF66...item4d445fce55

Looks like it's shared, are you plugging the yellow rca plug into the green and the red and white on the right side, not the middle red?Last edited by nomoresonys; 06-04-2019, 06:05 AM.

Could try heating the chip with a heatgun, too much heat can kill it tho, if it starts working you know that chip is the problem.Last edited by nomoresonys; 06-04-2019, 06:53 AM.

Hello friends, finally the fault is from the IC CXA2069Q, because i could not find the ic to replace, i just purchased a AV to VGA converter, did every connection inside the tv, most inportantly, i did not use the adopter that came with it, we all know is china and for duration sake, i did not use the 5v adopter that came with it, i took 5v to feed the converter so it will not be paminently on, i still used the AV3 as input to feed video and sound to tv. And everything work fine through ROB input. Thanks all
