Logitech Z906 will not turn on?

I have 2 Logitech Z906 systems that have been working properly. One now will not turn on, no lights, nothing.

I have checked the fuse and power to the end of the input plug, All seems fine. I did see somewhere about holding the power button on the remote for 8+ seconds to reset but this didn’t do anything either.

Anyone help please, I’m perfectly competant to pull it apart; although not an electrician I am an engineer and could probably/possibly fix it with guidance.

Hi @krisdvv

You will need to open up the defective and inspect the board.

I have a feeling the internal SMPS might be having issues, inspect the smd components carefully. somehow i think something must has shorted and burnt the smd resistors

OK I thought something like that, but I have no idea what I'm looking for or how to test it?

Hi @krisdvv ,

Post some close up images of the board(s) back here and hopefully someone will spot what you can't.

Here's how to do this on ifixit 在已经存在的问题里加入图片

The 3 images in Reply post #30 of this link shows what the damage may look like in your speakers if it suffered from the same problem but maybe not. Click on the images to get a close up view
