Hi friends, I got this TV, which had the bad source oscillator (according to the client for lightning), replace it, turned it on, with audio but without image, when you raise the brightness you see return lines without image, (it does not completely fill the screen from side to side), Sometimes the image appears, I lower the brightness again and the image looks good (without filling the entire screen from side to side), but I turn it off and on again and the image is no longer visible, replace the ic tda6107, remove the memory and program it and the problem persists, change the ic from vertical, and all the same as I can check, greetings and may GOD bless you

I will check and notice tomorrow, may GOD bless you
