Good afternoon. I have the problem that the TV starts well with its normal image and after 30 seconds or 1 minute of operation it starts to turn the image very white and with the colors in negative. I turn it off and wait a few seconds and when turning on everything returns normal for an instant equal to the previous one and fails. Being hotter the fault occurs in less time than before.
The fault occurs both in the image and in the menu box.
I would appreciate suggestions on this. Thank you very much greetings

I was wrong and I went to the motherboard to trident cx33. It coincides that it cooled it with clean contacts and remained a little longer. My big problem, I think, was that when I reviewed the service manual, I didn't find a TCON scheme, so when I said only that the output was going to the LVDS terminals I was left with the impression that the model did not bring TCON. but I opened again and found her. I am clear that I must extract the AS15-G IC, which apparently would be the cause. I will try to do it without harming and I tell you. Thanks for answering and guiding me.

Total success, I changed the integrated one and the problem disappeared. It takes 1 hour working excellently. Thank you. I am an electronics hobbyist. I studied Radio_TV, but old and basic method. Thanks to the contribution of people and groups like you on YouTube I have learned watching videos. I say this for the beginners, that you can with patience and desire to learn. Greetings.
