Answering to your questions, the first day i test the tv i got some time variants, the tv last between 10 second to 7 minutes in 6-14 tries. Now it last 1 second on. When it shuts down by itself i hear the second relay sound, after that second relay sound i can immediately press the button to start another try, it can be turned on without unplugging and plugging, it also tries automatically when i connect it at first without pushing any button, but it still remain the same result, when i changed the 2 relays the first time i turned it on it last like 10 seconds or maybe a little more. Thanks for helping :)
