Hi

I have recently been given a pair of Penta MkII speakers. Model 6622.
They are amazing and I already love them.
However, the LCD display on one is weirdly upside down. The other one has no display at all.
Should both displays be working together?

Should I try to fix the upside down display or just leave it well alone? It is quite annoying, but quirky, I suppose.

Thanks

The display was most likely installed upside down when a previous owner worked on the speakers and didn't have a way to test the displays. It should be an easy fix. Carefully remove the plastic display cover. The plastic will be brittle (new replacements are available if needed). IIRC, the display is held in by 4 screws. Remove, flip, reassemble, and enjoy your new Pentas.

If the other one has no display at all, please check the switch at the bottom of the speaker where you can turn the display off. I think it says Audio/Video - and the idea was to be able to turn of the display in a dedicated cinema room.

Hi

Thanks for your message.  I have already tried that but have just tried it again and still no display, so I think I need a new unit.

The orange display has a 7805  5V Power regulator chip, they become pretty hot for a long time. Check it, some of them are simply dead.
