How to repair Samsung T220G monitor at home?

Question

Do it yourself

The symptoms are as follows, for several days the patient blinked (as if the brightness of the backlight changed), then it went out. When turned on, the screen normally displays for a couple of seconds, after which it goes out. Expecting to see the breakdown visually (swollen capacitors, etc.), I performed an autopsy, but everything was clean. I am doing this for the first time (the skill of radio electronics is at this level: 15 years ago I soldered a detector receiver and a multivibrator on K155LA3). What to do, where to dig?

Answer 1

You can try putting it in the fridge. Or into the oven. There were a lot of articles on Habré;)

Answer 2

either lamps or transformer

Answer 3

check the resistance of the output windings of the transformer(s), it should not differ by more than 10 ohms
