Penta MkII display issue

[David Penny]

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.

The easiest way to start debugging this is to swap components between the working and non-working speaker. 1) PL cables and connections, 2) amplifiers, 3) check the soldered wires on the inside of the display connector on the bottom plate of the speaker, 4) display boards.
