HP65 display issue

[ThomasF]

That can be seen in my "after" picture, the middle display is slightly brighter then the other two. In my case, the first module I changed apparently already was broken (as the 45 calculator was DOA I couldn't have known, but at my second attempt with another module I got it working. The brightness issue is seen in the picture but not really noticable for the naked eye.

I'm used to solder my own boards for hobby, and I had no problem desoldering the modules with a non-professional solder iron, and with a cheep de-soldering "gun", just being careful when doing it. It might be I was lucky, both with the soldering and with the modules.

Anyhow, that was my short story on how I managed to get the 55 working again and I'm happy to share that story.

Best regards,
Thomas
