Hello! I am new to electronics, and this forum is fantastic. I have the following problem, I have an Ansonic 32HD1 tv, a generic brand from Vestel, with a 17IPS11-R4 power supply and main 17mb55.
The tv has no backlight, but it also has no image and sound. when it turns on the standby light blinks several times, and there is a very short flash of the backlight, as if it wanted to start, but it does not start. I have measured the voltage on the red wire of the backlight, as you have seen on the forum, and in standby it has 30v, and when it turns on it goes up to 100v and slowly drops to almost 30v. If you disconnect the lighting, it does the same thing but it starts at 0v and ends at 0v. In the source there are present 12v, and 3.2v. Let's see if they can help me. Thank you very much in advance
