Good day, if you are good in soldering you can change it, pay attention of the
circuit board coz the small size of the diode and just use a thin soldering iron tip.

Thanks david for the respond

Yes, i’m ordering the component and try to replace it.

Have you got same experience with me ? Why the LG33 getting hot ? do you think this is due to bad component or there is something else ?

Thanks

Good day, i didn’t experienced an issue like this. you.
The cause can be an internal short circuit or if the diode was defective.
