Question LG Soundbar SH7 power issue

[jalle65]

Hey! I have a LG Soundbar SH7 -model. It was working fine, until the other day, honestly without doing anything to it, it just didn't turn on anymore. Anything I do, doesn't work, I've pressed all the buttons, tried different combinations, it won't turn on. A red light is still present in the front of the soundbar, but it won't turn blue, like it would if it turned on normally. The red light is not blinking, it's just static.

I also bought a new power adapter, but it wouldn't turn on with that either.

Anyone have any suggestions what to do? Thanks in advance!

Nothing you can do yourself to fix this, contact LG support if it's in warranty.
You can try unplugging it for a while and see if it does anything to reset it again.

Thanks for your reply. Do you know why it does this? I'm pretty experienced in opening and maintaining electrical devices, can I swap like a power management chip or something?

No way to know it without opening it and checking voltages on the board, and no, I don't know exactly what to check for in that model.
