Good evening sorry for the absence, thanks for the support, the problem was in the cables that go from the coils to the card there were two games internally I do not know the reason since the TV came from another workshop and they brought me for failures after a rise in light. but I think I should have tried those cables from the beginning. the problem is that the client took the tv at 2 weeks brought it back to me since the tv turns on and turns off immediately, what would be the steps to start in solving this problem, I appreciate your help since I'm not very expert on this
Good morning I already solved the TV problem. I did not comment before because I had to travel for a sick relative, I commented that the problem of turning off the TV that goes next to the flyback 1 ohm that makes a kind of fuse the resistance was heated and the TV was turned off, I changed it and ready, thanks everyone for help and sorry for the delay.
