I found no configurable jumpers at all on the display. There is a large ribbon cable and a small ZIF header cable. I reseated both, and the display corrected. Not sure if it long term, time will tell.

Thanks to all that replied.

It fixed itself and worked for a few weeks. It happened again today. I will have a look and see if I can find these jumpers and report my findings.

Thanks!

Used it all day and shut it down normally. Next day, powered it up and the display came up upside down and a mirror image.

Tried the usual fixes...factory default reset, power cycling, let it sit a few hours disconnected from power. No go. Then many hours later, I turned it on and it went back to ...

I have an analyzer that exhibits low levels. The problem has been isolated to the RX IF block. With no schematics and no support from the manufacturer, I am on my own and going nowhere fast.

Anyone have experience troubleshooting this module at component level?

Thanks!
