Service center technician said the main board has to be replaced.
But they are not wiling to repair the main board in component level. Guess they prety much saves time but replacing the whole board rather than spend time locating the faulty component.
Can anyone give me a starting point to start diagnose the main board by myself. I’m a hobbyist and have slight knowledge of electronics.
So you can be technical with your answers.
Help would be highly appreciated!
