I've already posted a question here about this when I realized that all things were not right with my Altera DE2 board:
After verifying that the segment indeed is broken, I contacted Altera who could send me new segments that they mean should be able to replace the faulty part.
But how do I replace a segment? Do I need to do soldering? When I turn around the board and look at it, it looks like the segments are soldered and that the only way to repair my board is if I do soldering and solder on a new part. Is this operation too risky, what alterantives do I have? Did I understand correct that I must solder?

Thank you very much Gina. Maybe I have another question how to mount the parts when it arrives, and therefore I might contact you again with a question when the parts have arrived. I wonder if I must solder the new display or how the new display will mount to the board.

It seems that segment E of HEX 3 is broken after I performed additional tests. This is a new DE2 board bought from Altera in August via my university program kth.se and the board has no signs of damage but segment E of HEX 3 display is not working:
Can it be repaired or replaced or can you suggest a solution?

There is a tool- control panel provided in the CD-ROM, please use it to test the function of the 7-segment displays on board. And feedback us the result.
If it really exsits the problem onto the segment, please contact our sales team for a solution, thank you.
Free to contact us if you have any other inquiry.

Niklas Rosencrantz 写道: Hello I bought a new DE2 board via myUniversity program (kth.se) Now I wonder about a technicality that I've written to the forum and asked about http://www.alteraforum.com/forum/showthread.php?t=37522 Is this display broken or is it a bug? It looks like a segment E on the display is not working and that this is a broken segment:
That is in segment E where is says 9 there should be an 8 and I can't get that segment to light no matter what tests or programs I run.
Is this something you can help me with, is my new DE2 card broken, was it a bad solder / joint that has gone up during transport or is this - unlikely as it may seem - a software bug? I think everything seems that segment E in one of the displays is broken and I wonder what can be done about it - fix it, replace and/or buy new part or new board?
Thank you Niklas Rosencrantz
With an experienced engineer I looked at the board and the engineer almost immediately said that we should handle it over to some expert and since the board is about new the warranty should handle this and I should bring the board in to where I bought it so that is what we are going to do. Because if I solder it myself I must destroy the warrant of the product which was bought as late as in august from Altera in Taiwan via their Stockholm office in Kista.
I now got a complete replacement board from Altera but it's the "better" DE2-115 so now my old.sof file won't work anymore...
