Daewoo TV model drq-20v1scm cn001m does its function of turning on and off but when you turn on you don't see the bone screen it goes black as if it had not turned on. The only measurement I made in the line of the 133v flayback and has 225v has a lot of voltage in advance thank you colleagues I hope you can help me

suggestions.- 1.- you remove the flyback and the hot, you place a 75/100 focus of the bmas to ground, this so that the source has a load, you place your voltmeter in the bmas pin of the flyback and check how much you have of bmas . 2.- you place your frequency meter in the base of the hot and check how much you have of frequency, they should be 15750. comments. greetings everyone.
